  • Experimental and numerical study on the stability capacity of Q690
           high-strength circular steel tubes under axial compression
    • Authors: Hui Wang; Yonghua Guo; Yongtao Bai; Bin Zhang; Qing Sun; Jianyang Xue
      Pages: 843 - 861
      Abstract: This paper presents experimental investigation on the local and overall buckling capacity of Q690 high-strength circular steel tubes under axial compression. Coupon tests are undertaken to obtain the Young’s modulus, Poisson’s ratio, tensile yield stress and ultimate tensile strength of Q690 steel material. Forty-two specimens under axial compression are tested to evaluate the buckling behavior and the failure mode. Test results indicate that most of the existing design standards are conservative for the design of Q690 steel tubes. The distribution model of residual stress is measured by cutting ring method. Then, a finite element model based on modified column deflection curve method (CDC) is built to assess the effects of initial imperfection and residual stress on the stability capacity of the steel tubes. Finally, design methods and recommendations are provided for estimating the stability capacity of high-strength circular steel tubes.

  • Numerical study on lateral buckling of fully bonded sandwich pipes
    • Authors: Zhe Wang; Zhihua Chen; Yongyu He; Hongbo Liu
      Pages: 863 - 875
      Abstract: Sandwich pipes (SP) are promising subsea pipelines for deep-water applications. Thus, their lateral buckling response is a significant design aspect. The temperature field of SP denotes the load in lateral buckling analysis, and it is calculated using the heat transfer differential equation in this study. A general temperature field formula is proposed for an arbitrary multilayer SP, and this formula is verified by finite element models. Another finite element model based on the fiber shell element is then constructed to investigate the lateral buckling response of SP. They are validated by existing experimental and numerical results. The evolution of the lateral buckling profiles and of stress distribution are studied in consideration of nonlinear pipe-soil interaction and nonlinear material constitutive law. Moreover, the influence of initial imperfections and pipe-soil interaction on lateral buckling response is examined. Finally, a formula is approximated for a SP with a half-wave sinusoidal imperfection profile on the basis of dimensionless analysis and numerical results. This formula is convenient for engineering applications.

  • Post tensioned tendons for seismic retrofitting of weak bolted T-stub
    • Authors: Vahid Saberi; Mohsen Gerami; Ali Kheyroddin
      Pages: 877 - 891
      Abstract: Current design philosophy for conventional steel moment resisting frames (MRFs) in high seismic regions is that the frames should not collapse for major earthquakes. However, significant structural damage and residual drift due to inelastic deformations in beams and columns may cause loss of building occupancy or operation after major earthquakes. On the other hand, Selecting the optimum technique for rehabilitation of existing structures with weak connections has been a challenge for engineers in the recent years. In this study, the authors proposed using post-tensioned tendons for rehabilitation of bolted Tstub connections with weak bolts or weak T-stub flange as well as a technique for changing pinned connections to moment connections. Six corner connection specimens are made and tested under SAC cyclic loading protocol. The results of this study show that this rehabilitation technique not only modifies the cyclic behavior of weak rigid connections and changes simple bolted connections into moment connections, but also it improves the behavior of the rehabilitated connections in a way that their behavior is more desirable than that of the reference rigid connection designed according to AISC. For example, flexural capacity and rotational stiffness of the retrofitted connections are higher than those of the reference connection by 18 and 26% in average respectively. Besides, rehabilitation using post tensioned tendons add self-centering ability to the retrofitted connection that has a major role in preventing permanent deformations in frame and thus, the possibility of using frictional dampers in self-centering frames for increasing the energy absorption capacity is provided. This rehabilitation technique in bolted connection with weak T-stub flange has better cyclic behavior compared to that of a connection with weak bolts, since the T-stub participates in energy absorption and higher energy absorption is reached.

  • Experimental study and numerical analysis on mechanical behavior of
           T-shape stiffened orthotropic steel-concrete composite bridge decks
    • Authors: Xu Jiang; Qingtian Su; Xu Han; Changyu Shao; Liang Chen
      Pages: 893 - 907
      Abstract: A new-type of orthotropic steel-concrete composite bridge deck system was developed, by casting the concrete overlay on the top of the orthotropic steel deck ribbed with T-shape steel members. To study its mechanical behavior (in terms of failure mode, load-deflection relationship, concrete crack initiation and propagation, strength, stiffness and so on), two new-type orthotropic steel-concrete composite bridge decks with different section dimensions were experimentally investigated and two reference decks (reinforced concrete deck and orthotropic steel deck) were also involved in the research for comparison. For the two new-type orthotropic steel-concrete composite decks, the average value of ultimate loads per width is 885.7kN, which is 2.35 and 1.61 times of that of the concrete and steel reference decks with almost the same section height. Experimental results proved that the composite deck can effectively control the crack initiation and propagation in the concrete and postpone the yielding of the steel bars and steel plates, due to the composite action between the concrete overlay and the underlying steel plate. Furthermore, the Finite Element (FE) model of the orthotropic steel-concrete composite deck was developed and validated by test results. A parametric study is conducted regarding to the stiffness of shear studs. With the validated FE model, stress distribution in the underlying steel plate and T-shape stiffeners and development of concrete cracking in the concrete overlay were characterized at different load levels.

  • Stability analysis of closely star-battened member of transmission tower
    • Authors: Jun-ke Han; Chun-lei Zhang; Zhen-bao Li; Xu-ming Wang
      Pages: 949 - 956
      Abstract: Stability of the closely star-battened member of a power transmission tower were researched in this paper, a theoretical analysis was conducted for the buckling mode of the closely star-battened member by different plate batten arrangements. The analytical method of the buckling capacity on the closely star-battened member was proposed here considering an arrangement type of the plate batten and they are compared with the results of a full-scale test. The conclusions are follows: the flexuraltorsional buckling did not happened for the closely star-battened member; the flexural buckling need to be calculated only after the strength reduction factor was considered; the stability-bearing capacity of the closely star-battened member of the line-shape type batten is slightly less than that of the cross-shape type batten; the stability-bearing capacity of the closely star-battened member can be improved when the number of bolts in the plate batten increases in a suitable extent; and the stability-bearing capacity calculated and test results agree well with each other when the stability-bearing capacity analytical method of the closely star-battened member was used to analyze the full-scale test tower. The experimental results show the calculation method is reasonable.

  • Experiment study on fatigue performance of perforated shear connectors
    • Authors: Xing Wei; Lin Xiao; Shiling Pei
      Pages: 957 - 967
      Abstract: In order to investigate the fatigue behavior of perforated shear connection in steel-concrete composite bridges, 24 connection specimens with different geometric configurations were subjected to static and fatigue testing protocols. Using the design shear resistance of perforated shear connectors obtained from static push-out tests as a reference load level, numbers of fatigue cycles under different cyclic load levels were determined. Accumulated relative slip between steel and concrete components was used to characterize and track fatigue damage accumulation. The relationship between cycle numbers and accumulated relative slip between steel and concrete was established. Test results revealed that the fatigue damage of perforated shear connectors can be divided into three stages, and fatigue life of perforated shear connectors can be evaluated by the accumulated slip, which depends on the maximum shear stress and stress range.

  • Thermal and mechanical properties of structural steel SN400 at elevated
    • Authors: In-Rak Choi; Kyung-Soo Chung; Hyerin Lee
      Pages: 999 - 1007
      Abstract: The accurate estimation of thermal and mechanical properties is a prerequisite for the reliable fire-resistant design of steel structures, considering that steel is used as one of the main materials for buildings due to fast construction, light weight, and high seismic resistance. For this reason, an experimental study was performed to examine the thermal and mechanical properties of SN400, one of structural steels for buildings, at various temperatures ranging from 20 to 900oC. For thermal properties, thermal conductivity, specific heat, and expansion of SN400 were investigated. For mechanical properties, steady-state tension coupon tests were conducted. The yield strength, elastic modulus, ultimate tensile strength, and stress-strain relationships of SN400 were investigated. The measured properties of SN400 were compared with those of other mild-strength steels and predictions by current design guidelines.

  • Determining the bilateral and unilateral mechanisms of tensegrity systems
    • Authors: B. Shekastehband
      Pages: 1049 - 1058
      Abstract: Tensegrity systems as kinematically and statically indeterminate pin-jointed systems are characterized by mechanisms and self-stress states. Taking into account the unilateral rigidity of cables may cause other mechanisms (unilateral) rather than bilateral infinitesimal mechanisms to be produced. Two numerical methods are presented for determining of bilateral mechanisms in tensegrity structures which are based on the geometrical characteristics and positive-definiteness of the tangent stiffness matrix, respectively. These methods allows distinction between first-order and higher order mechanisms. A numerical method is submitted for determining the unilateral mechanisms of these systems which uses the basis of the self-stress states for identifying prestressed and non-prestressed cable elements.

  • Flexural behavior of anchor horizontal boundary element in steel plate
           shear wall
    • Authors: Ying Qin; Jin-Yu Lu; Li-Cheng-Xi Huang; Shi Cao
      Pages: 1073 - 1086
      Abstract: Steel plate shear walls (SPSWs) have been increasingly used in lateral load resisting system since the post-buckling strength of web plates was realized and considered in practical design. Diagonal tension field is formed in the web plate to resist the lateral force induced by winds and earthquakes. The force is anchored by the surrounded horizontal boundary elements (HBEs) and vertical boundary elements (VBEs) and eventually transferred to the ground. Therefore, the response of HBEs, especially anchor HBEs, is essential to ensure that SPSWs could exhibit the required strength, ductility, and energy dissipation capacity. This paper presents the results of theoretical studies into the flexural behavior of the anchor HBEs of SPSWs and can be regarded as an extension to the previous work by Qu and Bruneau (2011) and Qin et al. (2017). The boundary effect was considered to reflect the actual stress state at the HBE-to-VBE connection, which assembled the method by Qin et al. (2017). Furthermore, more proper distributions of the vertical component of tension field for the positive and negative flexure cases, respectively, were proposed comparing to the work by Qu and Bruneau (2011). The hand calculation approach for the plastic flexural capacity of the anchor HBEs was given by the summation of the contributions from the flanges and the web. The developed equations are compared with previous data and good agreement was found between them. Meanwhile, comprehensively discussions are conducted to evaluate the influence of key parameters on the flexural behavior of anchor HBE. It was found that the plastic flexural capacity of anchor HBE decreases from unity to the minimum as a result of the increase in shear force, axial force and vertical stresses. Moreover, the flexural response of anchor HBE is most vulnerable to the change in shear force. This indicates that boundary effect is significantly important and cannot be ignored in the analysis. The research in this paper provides basis for the capacity design of anchor HBE.

  • Effect of inverted-V bracing on retrofitting against progressive collapse
           of steel moment resisting frames
    • Authors: Farshad Hashemi Rezvani; Mohammad Ali Mohammad Taghizadeh; Hamid Reza Ronagh
      Pages: 1103 - 1113
      Abstract: The effect of inverted-V bracing on enhancing progressive collapse resistance of steel Moment Resisting Frames (MRF) were investigated in this study. A series of nonlinear static and dynamic analyses were performed to determine the resistance of four generic MRFs retrofitted by ten inverted-V bracing element. These structures were subjected to an exterior column loss and had a different number of stories and span lengths in order to study the effect of these variations on the structural response. Both force-controlled and deformation-controlled actions were implemented to determine if the column loss would lead to a failure progression. Results showed that structural configuration affects the structural resistance against failure progression and hence the appropriate brace element to retrofit it. Also, it was shown that for the studied 4-story frames, by increasing the span length by 20%, the structural resistance decreases by 42% on average. Finally, it was observed that by decreasing the span length, the Dynamic Increase Factor (DIF) suggested by the UFC, will lead to underestimating the required cross-sectional area of the brace for strengthening the unbraced structures.

  • Collapse mechanisms of single curvature tensegrity systems
    • Authors: B. Shekastehband
      Pages: 1115 - 1129
      Abstract: Tensegrity systems are composed of any given set of cables connected to a set of struts in which cables connectivity must be able to stabilize the configuration. In the present study, the collapse mechanisms of single curvature tensegrity systems was investigated by carrying out nonlinear collapse analyses using finite element method. Having verified the finite element modeling with the experimental results, several different collapse analyses have been undertaken in order to examine the instability behavior of the single curvature tensegrity systems. Consequently, the different collapse mechanisms of this type of tensegrity systems have been determined. In addition, the effects of the self-stress level, and the effects of the post-buckling response of the struts and the post-yield response of the cables have been investigated. Based on the obtained results, some important conclusions have been drawn regarding the instability behavior of these tensegrity systems.

      Abstract: The traditional mode superposition method (MSM) is inefficient when applied to dynamic analyses of spatial lattice structures. The inapplicability and inefficiency of the MSM associated with spatial lattice structures are investigated and summarized in this paper. Based on mode selection and mode construction, a new modal set is constructed named Eigen- Loaddependent Ritz (Eigen-LDR) mode. Additionally, the computational procedure of the Eigen-LDR modes is presented. Furthermore, based on the constructed Eigen-LDR modes, a modified MSM, named the Eigen-LDR mode superposition method (EL-MSM), is proposed. Two typical spatial lattice structures, namely, a latticed shell and a spatial truss, are built as numerical examples. Seismic response analyses using the EL-MSM, including mode-superposition time history analysis and mode-superposition response spectrum analysis, are conducted simultaneously. The numerical results illustrate the accuracy, efficiency and generality of the method proposed in this paper.

  • Reducing the in-plane effect of infill on steel moment frame
    • Authors: A. Keyvani Borujeni; T. Mahdi
      Pages: 1171 - 1181
      Abstract: In this paper, four large-scale one-story steel moment-resisting frame specimens have been tested. The first specimen is a onestory steel moment-resisting frame without masonry infill walls. The second is similar to the first but with infill wall having full physical contact to the frame. The other two are non-structural infill walls. The first non-structural infill wall has a complete decoupling from the frame, while the second has a full contact at the top of the wall and separated from the columns. The results of this paper have shown that life safety performance level for non-structural infill wall having a complete decoupling from the frame has satisfied the allowable story drift. This was not the case for infill wall having full physical contact to the frame or nonstructural infill walls sepatared from two sides.

  • Investigation of composite action on seismic performance of weak-axis
           column-tree moment connections
    • Authors: Yinglu Xu; Linfeng Lu; Hong Zheng
      Pages: 1199 - 1209
      Abstract: This paper presents an experimental study on a developed weak-axis column-tree moment connection subjected to horizontal cyclic loading. In order to study possible positive or negative effect of a composite slab on the seismic performance of the proposed connection, six cruciform specimens were designed and constructed in pairs, where one specimen was bare steel joint and the other involved a composite slab. The standard, cover-plate, and material-changed connection details were considered. The test program is described in detail, and then the structural behavior of test specimens is discussed based on the test data. The tests revealed that although designed with 50% degree of shear connection, the concrete slab still caused obvious upward shift of the neutral axis and increase the strain demand on the bottom flange. But it is clear from the comparison of results that the composite joint specimens performed slightly better than the bare steel counterparts in terms of load-displacement hysteretic curves and energy dissipation capacity, as the concrete slab could effectively enhance the stability of the steel beam and delay the deterioration of the strength and stiffness. The cover-plate connection appears to be one of the more promising moment connection schemes which are able to deliver a much higher level of stability and energy dissipation capacity. The maximum magnitude of slab-steel beam interface slip was less than 0.5 mm, indicating that the concrete floor slab and steel beam could work well together under 50% partial shear connection.

  • Evaluation of quasi-static responses using displacement data from a
           limited number of points on a structure
    • Authors: Junho Choi; Keesei Lee; Jeonghwa Lee; Youngjong Kang
      Pages: 1211 - 1224
      Abstract: To maintain structural integrity, an effective method is needed to estimate structural responses using measured displacement data. It is necessary to determine the global displacements of a structure to evaluate its condition. However, fully determining the displacements can be difficult when insufficient measured displacement data are available. In this study, the SRALD 1.0 method is introduced for estimating the internal forces of a structure with limited displacement data. The suggested method involves two stages: deformed shape estimation and structural analysis. In the deformed shape estimation stage, the deformed shape of a structure is estimated using a limited number of displacement data. In the structural analysis stage, internal forces such as bending moments and axial forces are calculated using the estimated deformed shape. To validate SRALD 1.0, numerical analyses of bridges are conducted, and the characteristics of the parameters used in the newly developed method are analyzed. The estimation results are compared with those of conventional interpolation methods. Finally, the validity of SRALD 1.0 is confirmed.

  • Shear resistance of buckling-restrained steel plate shear walls
    • Authors: Mu-Wang Wei; J. Y. Richard Liew; Xue-Yi Fu
      Pages: 1233 - 1248
      Abstract: The buckling-restrained steel plate shear walls (SPSWs), which consist of a steel plate sandwiched in between by two reinforced concrete (RC) cover plates, are known to be a robust and efficient lateral load-resisting system. Since the initial imperfection between the RC plates and the inner plate which is mainly caused by the fabrication and construction errors, the high-order buckling deformation generally forms in the compression zone of inner steel plate. Therefore, a modified method based on the high-order buckling analysis on the inner panel is developed to predict the shear resistance of buckling-restrained SPSWs in the present study. Furthermore, the available experimental data from literature is employed to establish the validation of the modified method, and the shear resistance predicted by the proposed method reasonably agrees with the test results. In addition, the effect of the flexural stiffness of vertical boundary elements (VBEs) is also investigated. The minimum moment of inertia of VBEs is then proposed so that the inner steel plate fairly uniformly forms the tension field. Moreover, the pushover analysis is conducted using nonlinear finite element (FE) method to establish the validation of the proposed VBEs flexural stiffness. The FE results are then compared with that predicted by the proposed method and a reasonable agreement is generally achieved between them.

  • Experimental assessment of seismic vulnerability of precast concrete
           beam-to-beam connections with steel slit damper
    • Authors: Woo-Young Lim; Seonwoong Kim
      Pages: 1249 - 1260
      Abstract: Cyclic loading experiments for PC moment frames with beam-to-beam connections with a steel slit damper were conducted to evaluate their seismic vulnerability. Connections installed at the mid-length region of the beam as a connection between PC beams were developed to achieve fast-track construction. Shear links exist in each steel connection, having been designed based on rigid-plastic idealization as used in limit analysis assuming an elastic-perfectly plastic material. The main experimental variable is the shear capacity of the shear links. The links had shear capacity levels of 50, 75, and 100% of the beam shear capacity. Test results showed that the steel connections had an efficient energy-absorbing capacity and good structural performance. The energy dissipation was significantly dependent on the shear capacity of the shear links. Based on the experimental results, it is recommended that beam-to-beam connections with the steel slit damper should be designed as ductile connections with shear capacity levels lower than the design shear capacity of the beam.

  • Axial load capacity of cold-formed steel built-up stub columns
    • Authors: Mohamed Ghannam
      Abstract: This paper aims to investigate the axial load capacity of innovative cold-formed steel (CFS) built-up stub columns. Four innovative CFS built up section is presented in this paper. Each section is composed of combination of more than two elements as follows: channels, channels with lip, Sigma section and/or plates. The elements of each section are assembled together by using self tapping screws. The concentric axial load capacity of each of the four sections was investigated numerically by using finite element (FE) model using ABAQUS program. The FE model was verified against previous test data. The FE model was used to study different parameters that affect the load capacities of the innovative CFS built-up stub columns, these parameters are: columns profile, steel thickness, steel grade and longitudinal spacing between screws (fasteners), cross sectional area. The axial load capacities obtained from FE models are compared with the perdition of the Effective width (EW) method (available in Eurocode, Egyptian code, American and Australian standards) and direct strength (DS) method (Available in American and Australian standards).

  • Four-step tensioning construction method and experimental study for rigid
           bracing dome
    • Authors: Zhanyuan Gao; Suduo Xue; Tan Wang
      Abstract: Rigid bracing dome is a new pre-stressed space structure. In the study, according to the features of the new space structure, a four-step tensioning construction method is proposed and corresponding tensioning control principle is also given. The rigid bracing dome designed in the experimental study has a diameter of 6 m and is equally divided into eight parts in the circumferential direction. The four-step tensioning construction method is explored in detail. The synchronous symmetric tensioning schemes in eight directions, four directions and two directions are studied respectively. The deviations of the experimental model are analyzed by using the orthogonal test design method. The key experimental problems are analyzed to propose corresponding solutions. The construction method is simple and efficient. An appropriate symmetric tensioning scheme can be chosen according to the requirements of practical projects. The deviation of outer ridge cable force is mainly caused by the following factors: vertical coordinates of support and rods, and the lengths of outer ridge cable, inner ridge cable, inner ring rod, and outer ring rod. The coordinate deviations of center rods are mainly affected by the lengths of outer ring rod and inner ridge cable. The construction method and corresponding solutions can be used to guide engineering practices.
