  • Axial load capacity of cold-formed steel built-up stub columns
    • Authors: Mohamed Ghannam
      Pages: 1273 - 1283
      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).

  • A proposal for a seismic design process for a passive control structural
           system based on the energy equilibrium equation
    • Authors: Sang-Hoon Oh; Seung-Hoon Shin
      Pages: 1285 - 1316
      Abstract: A systematic design method for actualizing a passive control structure that can effectively exert its capabilities to minimize damage from an earthquake has yet to be presented. In particular, a clear method for placing EDDs that can improve seismic capability under earthquake delivery has yet to be presented, causing the dependence on the design of placing the damper after repetitive response analysis and trial and error work directly. However, in order to obtain seismic capability that the designer intends, the designer needs to be able to predict optimum placement of the damper prior to response analysis and determine the design result to be reliable. This study aims to suggest a design process of passive control structure, which includes design and placement of the damper for obtaining the seismic capability of the passive control structure as intended by the designer. Also, dynamic response analysis was conducted on structures designed using the design process suggested in this study to confirm whether the seismic capability intended by the design has been achieved, verifying the validity of the design process.

  • Experimental and analytical studies on bearing capacity of bolt connected
           composite plate girders
    • Authors: Yiyun Zhu; Jincheng Zhao
      Pages: 1317 - 1329
      Abstract: Composite plate girders bearing the enormous concentrated loads from boilers are common members in thermal power plants. Because of their large scale and sustaining distinct loads, the section of these girders is made of two parts combined with high strength bolts. Experimental investigations on two I-section plate girders, two homogeneous composite girders, and two hybrid composite girders, are implemented. Bearing capacity and member ductility are compared among the three kinds of specimens. To reveal the mechanism of composite plate girders, force method built upon the linear elastic theory is employed, according to deformation coordination among the components. The elastic stress distribution predicted by the analytical method is validated against test data. Based on the internal force distribution derived, the elastic effective width method in current specifications and the plastic effective width method proposed in other published literature are employed herein to predict the critical load. Conclusions can be made that bearing capacity of composite girders is superior to the I-section ones, and hybrid composite plate girders can further balance the economic and mechanical efficiency of constructions. Additionally, several proposals for application are offered.

  • Seismic performance of low-rise intermediate steel moment frame buildings
           in South Korea
    • Authors: Taewan Kim; Eunjong Yu
      Pages: 1331 - 1340
      Abstract: The seismic performance of low-rise intermediate steel moment frame buildings following design practices of South Korea was investigated and its benefit was presented in comparison with those of customary design practice in the United States. The major features in the design and construction practices in South Korea are that the entire frames of the building are designed to resist the lateral load and beam-to-column connections are fabricated in factories. In contrast, in the United States, only exterior frames resist the lateral load and the entire beam-to-column connections are welded at the construction site. To investigate the effects of distinctive design practices on seismic performance, the example buildings were designed and evaluated with the procedure in FEMA 355F. The effect of panel zone deformation in addition to story drift was considered in performance evaluation. The evaluation results showed that the seismic performance of the buildings designed in accordance with the practice in South Korea were not significantly different from those in the United States. Therefore, design and construction practices in South Korea are a competitive way for intermediate steel moment frame buildings.

  • Investigation of the structural behavior of an innovative steel open-web
           floor system
    • Authors: Huanqiang Luan; Kejian Ma; Ying Qin; Zhihua Chen; Yanhui Wei
      Pages: 1365 - 1378
      Abstract: An experimental study was conducted on a steel open-web floor system, in which the top and bottom chords are connected by a steel square tube to form a vertical web member. A full-scale flexural test was performed to evaluate the flexural performance and failure mechanisms of the floor system. The steel open-web floor structure demonstrated a satisfactory composite behavior, and the loading capacity increased to 2.6 times the working load. A parametric study was performed to examine the effects of three geometric properties. Increasing the size of the cross sections exerted a significant effect on stiffness, and the load capacity of the open web floor system was enhanced significantly. Results show that the design method and philosophy of the open-web floor structure are in accordance with Eurocode 4 and the Chinese Code for the Design of Steel Structures.

  • Numerical and experimental investigation of composite steel shear wall
           with opening
    • Authors: Abolfazl Arabzadeh; Hamid Reza Kazemi Nia Korrani
      Pages: 1379 - 1389
      Abstract: Shear walls are used in towers as lateral loading resistance. Composite steel shear wall (CSSW) because of high stiffness and deformability are widely used. This wall made of a thin steel plate with reinforced a concrete layer, which is attached to one or both sides of the steel plate. This system is similar to stiffened steel plate shear wall. The present experimental and numerical studies were focused on the effects of opening used as windows or doors in buildings on the CSSW behavior. Experimental studies results of one and three-story CSSWs with the scale of 1:3 are reported. In addition, the effects of opening size and location are insignificant on the composite steel shear walls behavior. Results showed that opening decrease CSSW strength. Opening at the sides and corners further reduces the resistance than Opening at the center.

  • Cyclic behavior of concentrically braced frames with built-up braces
           composed of channel sections
    • Authors: M. Nader Naderpour; Ali. A. Aghakouchak; Amin Izadi
      Pages: 1391 - 1403
      Abstract: Concentrically braced frames are earthquake resistant systems commonly used in buildings. Seismic behavior of this type of structures is affected by their configurations, brace properties, and brace to gusset plate connections. In this paper, the results of three experiments conducted to investigate the cyclic behavior of concentrically braced frames with braces built-up of double channels are reported. Significant damage was observed in beam to column connections. Large out of plane deformation of braces caused some cracks in the connector welds; however they did not result in fracture. Although large drift was applied to the frames, no brace fracture was observed. Furthermore, experiments showed that the majority of compressive strength in post-buckling state and a noticeable portion of tensile strength originated from frame action. By choosing connector spacing as the main parameter and using finite element models, a parametric study was performed to investigate the effect of this parameter on this type of frames with two different details of brace to gusset plate connections. It is observed that reducing the connector spacing increases the inelastic strain demand in braces and decreases it in gusset plates. However, gusset plates, which accommodate 2t linear clearance, are less dependent on connector spacing, compared to those accommodating 6t elliptical clearance. It seems that the limitations of slenderness ratio of individual section, stipulated in current seismic provisions, need further study.

  • Shear capacity of cold-formed light-gauge steel framed shear-wall panels
           with fiber cement board sheathing
    • Authors: Wasim Khaliq; Ahmed Moghis
      Pages: 1404 - 1414
      Abstract: Being light in weight, cold-formed steel shear wall panels (SWPs) made with light gauge steel are extensively used in residential and office buildings (low to mid-rise), particularly in structures under seismic loadings. Many design practices involve the use of fiber cement board (FCB) as sheathing material both for hollow and infilled walls. FCB is a preferred choice as cladding material due to many advantages it provides such as water resistance, lower cost, withstand temperature variation, resistance to humidity and termite attack, better acoustic insulation, and superior fire resistance properties. In the absence of design guidelines, based on cold-formed light gauge steel shear walls with FCB sheathing, the designers resolve to use the guideline available for gypsum wall board (GWB) and fiberboard (FB) available in American Iron and Steel Institute Lateral Design. As a pioneer study, an experimental program was designed to investigate the behavior of cold-formed light gauge steel shear walls, both hollow and infilled with expanded polystyrene (EPS) foam concrete, with FCB sheathing on both sides under monotonic loading. The tests were performed according to ASTM E564 standard. Results show that the strength of shear walls with FCB sheathing is much higher than GWB and FB sheathing, suggesting that substitute design practices are highly conservative. Test results can help designers choose desired lateral stiffness and load carrying capacity of light gauge steel SWPs more efficiently, by selecting appropriate framing, infill, and sheathing material.

  • Reliability-based optimization of steel truss arch bridges
    • Authors: Jin Cheng; Hui Jin
      Pages: 1415 - 1425
      Abstract: A reliability-based optimization approach is developed and applied to minimize the weight of steel truss arch bridges subject to probabilistic (the overall probability failure of the structure) and deterministic (stress and deflection) constraints. The method intelligently integrates the genetic algorithm (GA), the finite element method and the first order reliability method. A real-coded/integer-coded method is used to realistically represent the values of the design variables. Three GA operators consisting of constraint aggregate selection procedure, arithmetic crossover, and non-uniform mutation are proposed. The finite element method (FEM) and the first order reliability method are used to compute the value of the probabilistic and deterministic constraint functions. A numerical example involving a detailed computational model of a long span steel arch bridge with a main span of 550 m is presented to demonstrate the applicability and merits of the present method. Finally, several important parameters in the present method are discussed.

  • Study on the influence of the initial deflection and load combination on
           the collapse behaviour of continuous stiffened panels
    • Authors: Ming Cai Xu; Zhao Jun Song; Jin Pan; C. Guedes Soares
      Pages: 1427 - 1442
      Abstract: Using the finite element analysis, a series stiffened panels under combined normal loads and biaxial compressions are conducted to investigate the effect of several influential factors on the ultimate limit states. Two spans/bays FE model with periodical boundary condition is adopted to consider the interaction between adjacent structural members. The initial deflections assumed as Fourier components including symmetric and asymmetric modes are used to identify the half-wave number of collapse of the local plate, which is compared with half-wave number of buckling calculated by formula. Based on the numerical results, the influences of half-wave number assumed in the equivalent initial imperfection and loads combination on the collapse behaviours of stiffened panels are discussed. It is found that lateral pressure might increase the ultimate strength of stiffened panels for the stiffener-induced failure modes. The one half-wave region of local plate influences significantly the load carrying capacity of stiffened panels.

  • On the prediction of arresting efficiency of integral buckle arrestors for
           deepwater pipelines
    • Authors: Shunfeng Gong; Gen Li
      Pages: 1443 - 1458
      Abstract: Dedicated finite element models are developed to simulate the crossing of a pipeline integral buckle arrestor by a buckle propagating under the quasi-static, steady-state condition. In addition, broad parametric studies are conducted to identify the mechanism governing the arresting performance, which consider the geometric characteristics and material properties of the pipe and arrestor. Based upon the extensive study, the more reasonable empirical design formulas for the crossover pressure and the arresting efficiency are established by means of the partial fitting. Good agreements between the existing experimental results and the predictions demonstrate that the proposed empirical formula and the lower bound envelope line for the arresting efficiency provide a powerful design tool to estimate the arresting performance of such complex structure systems in engineering practices.

      Abstract: Post-tensioned (PT) self-centering beam–column connections has been developed for its good seismic performance. Many researchers have investigated its mechanical behavior by numerical or experimental method. Prior researches have indicated that the analysis by elaborate FE models is very time consuming. To overcome this disadvantage, a simplified numerical model was established in this paper. The accuracy of results derived by this model was validated against prior investigations on interior PT connections with top-and-seat angles. Influence of initial PT force on mechanical behavior of PT connection was investigated. The Geometric and material nonlinearities, and strands can be considered in the modeling. A planar steel frame structure was established and hysteretic analysis was conducted. Results indicated that the computational cost can be greatly reduced by this model.

  • Damage evaluation of reinforced concrete and steel frames under critical
           successive scenarios

      Abstract: This paper compares the vulnerability of initial shock-damage reinforced concrete (RC) with steel frames in successive scenarios, as an essential part of developing a framework to consider seismic sequence hazard into structural design. For this, two sets of regular RC and steel moment resisting frames with 3, 5, 7, 10, 12 and 15 stories, are designed and analyzed under two different databases with/without seismic sequences in OpenSees software.The damage states of the model frames were then measured by the Park and Ang’s damage index. From the results of this investigation, it is observed that only considering the mainshock will underestimate the seismic risk in both sets of RC and steel frames. The results of damage evaluation also reveal that RC frames have better performance than steel frames in seismic sequence phenomena. Furthermore, steel frames damage is about 53% more than the damage caused by RC frames under critical successive earthquakes.

  • Assessment of structural behavior of transmission line tower using strain
           gauging method
    • Authors: Veerendra Kumar Shukla; M. Selvaraj
      Pages: 1529 - 1536
      Abstract: Design of latticed steel transmission towers is a challenging task which involves lengthy modeling and detailing of significant amount of steel members and connections. After that full scale testing of towers validates the modeling and detailing and ensures that the towers are designed to withstand design loads without premature failures. In present work, a 132 kilovolt double circuit suspension tower has been considered for study. The tower was designed using Staad.pro software and the member forces were calculated at design loads. After design, the full scale testing of the tower was carried out. During testing, the strains in some of the critical members were measured using strain gauges. Using these strain values, the actual load in selected members are calculated. The paper provides the comparison between actual load in members during full scale testing and computed loads from software. The paper also discusses the possible reasons behind the difference between actual and computed loads. Loads on the tower at different points for different conditions are presented. The paper also provides a discussion about the possible reasons of premature failure of tower during full scale testing or at site and the remedial measures are presented to avoid the failure.

  • Vibration control of smart TMD for retractable-roof spatial structure
           considering closed and open roof condition
    • Authors: Hyun-Su Kim; Joo-Won Kang
      Pages: 1537 - 1548
      Abstract: A retractable-roof system is frequently adapted to the spatial structure of stadiums and sports halls. The geometric shape and mass location are varied by opening or closing the roof, resulting in a change in the dynamic characteristics of the retractable-roof spatial structure. A passive tuned mass damper (TMD) shows good vibration control performance of the spatial structures when it is tuned properly. Because the closed or open roof condition of a retractable spatial structure causes off-tuning, multiple smart tuned mass dampers (STMD) were developed in this study to increase the control performance in the case of off-tuning. Initially, the dynamic characteristics variations of the opened or closed roof conditions were investigated using an example retractable spatial structure. The control performances of a passive TMD and smart TMD were evaluated under off-tuning conditions. For this purpose, artificial ground motion was generated based on the Korean Building Code (KBC) 2016. Multiple smart TMDs were comprised of magnetorheological (MR) dampers. A fuzzy logic control algorithm (FLC) was used to generate the command voltages sent to the MR dampers and the FLC was optimized by a multi-objective genetic algorithm. Numerical analyses showed that the smart TMD had better control performance than the passive TMD. In the case of the off-tuning condition, the difference in control performance between passive and smart TMDs increased.

  • Experimental research and numerical simulation of a large-span isolated
           structure considering multi-dimensional input effects

      Abstract: Based on the shaking table test of 1:20 scale structural models of the large-span isolated and non-isolated flat grid structures under the action of horizontal-bidirectional (2D) and three-dimensional (3D) rare earthquake, the dynamic characteristics, including natural vibration frequency, damping ratio, the acceleration and displacement responses are investigated. The results show that the base isolation could significantly prolong the structural vibration periods and increase the damping ratio. The capacity of energy dissipation for the base-isolated structure can also be improved. The horizontal acceleration amplification factors (AAFs) of the structure can be reduced greatly due to the base isolation, which effectively reduces the vertical vibration of the large-span grid. Under the 3D seismic input, the horizontal AAF of each layer is greater than that under the 2D one, which illustrates that the vertical seismic input increases the horizontal dynamic response of the structure. Furthermore, the finite element models of the isolated and non-isolated structures were simulated. The experimental results are in good agreement with the numerical results. The parameter optimization of isolation bearings was conducted by using finite element software. The seismic response of each layer under different shear to weight ratios (μ) was analyzed. It can be found that the parameters of the isolation layer have an optimal range which makes the dynamic response of the structure reach a minimum value under the rare earthquake.

  • Seismic performance evaluation of a structure retrofitted using steel slit
           dampers with shape memory alloy bars
    • Authors: Asad Naeem; Mohamed Nour Eldin; Jinkoo Kim; Joowoo Kim
      Pages: 1627 - 1638
      Abstract: In this paper, a hybrid slit- shape memory alloy (SMA) energy dissipation device is devised by attaching a SMA bar to each face of a steel slit plate. An analysis model of a SMA bar with super elastic capability is developed using various link elements, and the accuracy of the analysis model is verified by comparing with finite element analysis results. The seismic performance of the hybrid slit damper is verified by incorporating them in seven-story steel structure. The nonlinear dynamic analysis results of the model structure subjected to seven earthquake ground motions show that the addition of SMA bars in slit damper results in significant reduction both in the maximum and the residual deformation compared to those of the structure installed with typical steel slit dampers.

  • An experimental study on bending performance of Hybrid forming composite
           beam

      Abstract: The new shape of Hybrid forming beam is a beam that two Z-shaped side plates and bottom plate are connected by high-strength bolt. By adjusting the height of Z-shaped side plate, it can be designed for required resistance and by adjusting the thickness of bottom plate and applying high-strength steel to it, nominal bending moment can be increased. In addition, if concrete is filled inside of the beam during the slab concrete installation process, it becomes the Hybrid forming composite beam which usability and fire resistance are increased. This study suggests the new shape of the Hybrid forming composite beam that applied high-strength steel to the bottom plate and this study acquired the conclusion as the following by the bending test. First, if the existing evaluating formula which evaluates the resistance of the couple moment by the compressive resistance and tensile resistance is applied to evaluating bending resistance of the Hybrid forming composite beam, the ratio of maximum load for the nominal load is more than 1.2 times on average, matches well with the experiment result. Second, if the bending stiffness of the Hybrid forming composite beam is calculated as the effective bending stiffness based on concrete that subjected to compression and steel that subjected to tension, it confirmed to reflect the experimental result well.

  • Shear behavior of large-diameter concrete filled tube (CFT)
    • Authors: Eun-bi Jung; Seo-Haeng Lee; Jung-Han Yoo; Charles Roeder; Dawn Lehman
      Pages: 1651 - 1665
      Abstract: Circular concrete filled tube (CFT) is composite structure to fill concrete in steel tube as formwork. By combining advantage of steel tube and concrete, CFT has more superior deformation capacity and strength than reinforced concrete and steel structure, since bond stress between steel tube and concrete has influence on prevention of local buckling and increase in strength of concrete. For such a reason, CFT has been applied to as columns in buildings, and pile and drilled shaft foundations. CFT drilled shaft is designed to large diameter due to large local shear strength by seismic load, liquefaction and lateral spreading of soil layer. However, it brings uneconomical design by the conservative shear equation of current design provision. Until today, shear studies of circular CFT to improve shear equation have been rarely conducted and they are limited to small scale test. In this research, the numerical and experimental results are compared to current shear design equations, with the ultimate goal to serve as an initial analytical study that aids in planning further experimental and analytical research on shear resistance and behavior of circular CFT, which leads to improved shear design equations.
