  • An AHP Framework for Evaluating Construction Supply Chain Relationships
    • Authors: Soo-Yong Kim; Viet Thanh Nguyen
      Pages: 1544 - 1556
      Abstract: Abstract Managing business relationships between customers and suppliers at different ties is the essential element of supply chain management in construction. The Construction Supply Chain (CSC) relationships among the parties should be continuously evaluated and improved to enhance the effectiveness of supply chain management. Hence, a model or an evaluation framework of the CSC relationships should be built to measure and assess the relationships among the parties. However, existing models and frameworks had some obvious deficiencies, for example, the weights of criteria for evaluating the CSC relationships have not been determined yet. The AHP method has been adopted in this study to build up a framework for evaluating the CSC relationships. Based on a comprehensive literature review, survey questionnaires, factor analysis method, and AHP method, an evaluation framework was formed, which includes the detailed weights of three main criteria and twelve sub- criteria, five levels of assessment, and nature of measurement. The criteria in this framework provide a rich and structured understanding of what occurs in CSC relationships among the parties. The framework may help the parties to measure and improve their current relationships with others in the supply chain.

  • Measuring Project Performance in Consideration of Optimal Best Management
           Practices for Building Construction in South Korea
    • Authors: Hee Sung Cha; Ki Hyun Kim
      Pages: 1614 - 1625
      Abstract: Abstract A variety of Performance Measurement Systems (PMS) are aimed to provide owners and contractors with sound decision-making by identifying the Best Management Practices (BMP). Most of them, however, are not effectively linked with project characteristics (i.e., project type, owner requirement, and/or project circumstances). Furthermore, a continuous feedback system is necessary in order to pin-point “how-to” solutions for the subject project. Compared to the conventional PMS, this study is focused on; (1) identifying, if any, quantifiable relationships among project characteristics, project performance, and BMP; (2) developing a systematic framework for predicting the performance level of the subject project; and (3) validating the feedback algorithm by detecting the most suitable management practices for a given construction project. Although the proposed system is limited to Korean building construction industry, the main contribution of this research is twofold. First, this study has conducted the first-ever empirical analysis by quantifying the project performance and selecting the optimal BMP in consideration of project characteristics. Second, the continuous feedback approach in the field of PMS is proven by effectively diagnosing the vulnerability of the project in terms of the various types of project performance.

  • Soil-atmosphere Interaction as Triggering Factors of Openings between
           Embankment and Pavement
    • Authors: Yongzhen Cheng; Xiaoming Huang; Chang Li; Lianyou Li
      Pages: 1642 - 1650
      Abstract: Abstract The analysis of openings between embankment and pavement due to uneven deformations of the highway embankment is incapable of accurate prediction when the pattern of seasonal weather variation is considered. This realization was used for elaborate openings analyses which include infiltration and evapotranspiration of the embankment soils to better predict atmosphere-induced openings between embankment and pavement at Nairobi where the longitudinal cracks of the pavement structure occurred during the period of the season alternation. The empirical equations were used to estimate evapotranspiration and the soil–water characteristic curve was established for the embankment soils. The consolidation theory and the moisture swelling model were then used to estimate performances of the highway embankment under atmospheric influence. A field test was conducted to verify the simulated moisture change in soil and soil movement, and small difference between simulated and measured values was found. The results showed that openings between embankment and pavement would occur when the highway embankment had undergone uneven deformations due to the rainfall and evapotranspiration, there were small openings during the dry season, but the maximum openings reached 10.2 mm and 25.5 mm during the first rainy season and the most intense rainy season, respectively.

  • The Probabilistic Stability Analysis of Saturated-Unsaturated MH and CL
           Soil Slope with Rainfall Infiltration
    • Authors: Khalid Mahmood; Jin Man Kim; Hassan Khan; Muhammad Safdar; Usman Khan
      Pages: 1742 - 1749
      Abstract: Abstract It is well known that the slope failure in unsaturated soil is the decrease in the matric suction, when the rain water infiltrates. However, the seepage mechanism and the stability of unsaturated soil slope have not been well established in geotechnical engineering. In this study, the suction profile and reliability index of saturated-unsaturated slope is studied at different rainfall condition with intensity in the range of saturated hydraulic conductivity of MH and CL soil. The finite element seepage model is uncoupled with slope stability model to calculate the reliability index at different time of long duration uniform rainfall. For CL soil slope, the reliability index is slightly changed during and after rain fall infiltration. For the MH soil slope the wetting front remains unsaturated up to a certain time of rainfall infiltration. After this time, the infiltrated rainfall reaches the ground water table and elevates it. The reliability index of the soil slope is thus reduced.

  • 3D Dynamic Finite Element Analyses and 1 g Shaking Table Tests on Seismic
           Performance of Connected and Nonconnected Piled Raft Foundations
    • Authors: Alireza Saeedi Azizkandi; Mohammad Hasan Baziar; Ali Fallah Yeznabad
      Pages: 1750 - 1762
      Abstract: Abstract Connected and disconnected piled raft foundations have been evaluated under lateral cyclic loading in this study. Connected Piled Raft (CPR) and nonconnected piled (NPR) foundations were considered and evaluated in 1-g shaking table tests. FEM numerical modelling also was employed to evaluate the results. The responses were evaluated and compared using lateral movement of caps, moments and lateral loads along the piles and ground settlements. The results indicate that both nonconnected and connected piled raft foundations effectively reduce the ground settlements, however, connected piled rafts have much higher lateral stiffness and piles contribute to lateral load bearing mechanism more effectively; in connected piled raft, piles bear higher moments and lateral loads and reduce lateral movements more effectively. The cap weight and superstructure (central mass height) effect has been considered through supplementary numerical assessments for CPR case. Superstructure addition tends to increase the pile moment and raft inclination where the frequency effect is also critically important. Also heavier cap experiences higher rotations and associated with higher induced loads to piles.

  • A Study on Cold-Formed Steel Compound Angle Section Subjected to Axial
    • Authors: G. Beulah Gnana Ananthi
      Pages: 1803 - 1815
      Abstract: Abstract The objective of our work is to examine the compressive strength on pin-ended thin-walled steel built-up double angles placed as a box section. Four types of cross sections with two different thickness are chosen for this study. A total number of 16 columns both stub and short columns are tested till they reach their ultimate strength. The built-up box angle sections consist of two identical lipped angle sections oriented face to face and connected with self-drilling screws through the lips in a particular spacing along the entire length. By using the ABAQUS software, a numerical finite element is set up to validate initially by verifying the experimental data on the behavior of built-up box angles. The Finite Element Model (FEM) holds both the geometric and material non-linearities. A study of parameter is done following the confirmation of the FEM on columns with different slenderness ratios ranging between 20 to 120. The quantitative results showed that they agreed well with the data of the experiments. Comparison is made with the two experimental and the numerical outcomes using DSM (Direct Strength Method) strengths. A recommended design is put-forth using DSM to calculate the eventual load carrying capacity for the built-up box angle sections.

  • Prediction of the Failure Stress of Hydrogen-rich Water Based Cement
           Mortar Using the Weibull Distribution Model
    • Authors: Byung Wan Jo; Sumit Chakraborty; Muhammad Ali Sikandar; Yun Sung Lee
      Pages: 1827 - 1839
      Abstract: Abstract The paper presents the compressive strength distribution pattern of the hydrogen-rich water based cement mortar. In this study, the mortar samples were fabricated using different concentrations of hydrogen-rich water (0.2-0.5 ppm). The performance of hydrogenrich water was evaluated measuring the setting time and the compressive strength of the mortar samples. Subsequently, the strength data were statistically analyzed using the Weibull distribution model in the 37% and the 95% confidence level (survival probability). Analyzing the results, it is anticipated that the use of hydrogen-rich water for the fabrication of mortar leads to set the cement quickly and yields comparatively greater compressive strength than that of the control mortar prepared using normal water. Based on the Weibull distribution analysis, it is predicted that the mortar prepared using 0.5 ppm hydrogen-rich water would not break under 31.46 MPa compressive stresses in 95% cases. Finally, based on the scanning electron microscopy in conjugation with the X-ray diffraction and thermogravimetry analysis, a plausible model has been proposed to explain the overall performances of the hydrogen-rich waterbased mortar.

  • Evaluating the Effect of the Thickness and Yield Point of Steel on the
           Response Modification Factor of RC Frames Braced with Steel Plate
    • Authors: Reza Aghayari; Sadegh Dardaei
      Pages: 1865 - 1871
      Abstract: Abstract Steel Shear Walls (SSW) in buildings are known to be an effective means for resisting lateral loading. By using un-stiffened walls and allowing them to buckle, their energy dissipation capacity will increase significantly due to the post-buckling capacity. The features of this system are being economical, quick and easy construction, low weight compared to similar systems, high ductility, high energy absorption and substantially reducing residual stress in structures. New methods and technologies obtained in the field of metals have provided new steel materials (LYP) to that has lower yield strength than conventional steel A36. This type of steel material shows the ability to deform and absorb more energy before failure. In this study the behavior of reinforced concrete frames braced with steel shear walls (LYP) was investigated and compared with other medium and high strength steel with different thicknesses. A nonlinear pushover analysis was performed. The effect of thickness of steel plate on the response modification factor was investigated. The results show that the lateral load capacities of RC frames braced with steel shear walls increase significantly and the response modification factors of RC frames braced with thin LYP steel plate is higher than the other systems.

  • Experimental Study on Shear Behavior of the Interface between New and Old
           Concrete with Reinforced
    • Authors: Cheng Maili; Ma Jing
      Pages: 1882 - 1888
      Abstract: Abstract In order to investigate the shear behavior of the new and old concrete interface, three kinds of reinforced concrete models with new-old concrete anchorage reinforcement were designed and fabricated. The semi-cyclic loading test was carried out. The failure mode, shear bearing capacity, interfacial shear slip and stress distribution of steel bars were analyzed. The test results show that the failure mode of the old and new concrete reinforcement at the interface was split type shear failure. The shear bearing capacity of reinforced concrete is mainly related to the shear resistance of concrete and the dowel pin shear, and the maximum value is about 1.186 × 104 kN/m2. The shear bearing capacity of stirrups reinforced concrete is increased by 28.5%. According to the obvious interface slip, the working state of the interface between rebar bolt and concrete can be divided into the stage of interface bonding and the stage of the friction. The lower part of the tendons is mainly cut and its upper part is shear-based. The largest stress is obtained at the interface and it decreases gradually to both ends. By analyzing the test results and relevant research, the formulas for calculating the shear capacity of the new and old concrete interface are derived. The results show that the formula of shear capacity is correct and feasible.

  • A Windowed Adjustment Function Based NRC Compliant Ground Motions for
           Fragility Analysis of Base-Isolated Nuclear Power Plant
    • Authors: Kaiser Ahmed; Dookie Kim
      Pages: 1900 - 1910
      Abstract: Abstract This research presents the influence and sensitivity of United States Nuclear Regulatory Commission (NRC) design spectrum matched multiple ground motions on the development of fragility functions for a base-isolated nuclear power plant (BI-NPP) structure using a new function. A multi-damping adjustment function called windowed tapered cosine adjustment function in time domain is introduced as ground motion modification scheme and its sensitivity is quantified over linearly scaled ground motions (GMs). Spectrally matched and linearly scaled unmatched, both types of GMs are scaled to same PGA level to make sure they have the same GM intensity during structural analysis. Time history analysis of a BI-NPP is carried out to evaluate the efficiency of the windowed adjustment function in the context of seismic response prediction. Fragility curves are developed considering peak ground acceleration (PGA) as ground motion intensity measure using the maximum likelihood method. The lateral displacement of the lead rubber bearing (LRB) has been considered as prime response parameter. It is observed that the windowed adjustment function gives 1.5-2.0 times higher responses found from the ratio of maximum displacement from spectrally matched to linearly scaled GMs.

Taking the Jigongling Tunnel of Fanba Expressway as an example, firstly the evaluation target was divided into 8 clustering indices and 4 grey categories according to the grey clustering method. In order to avoid the defects that the traditional whitenization weight functions could not give a good description of system’s randomness and ambiguity, the cloud model was introduced to improve it. Then the whitenization weight values were discretized by using the one-dimensional forward cloud generator to simulate the uncertainties in engineering, and the normal grey cloud whitenization weight functions were established. Afterwards, combined with the engineering data of Jigongling Tunnel collected on site, the clustering weight of each clustering index was analyzed under specific engineering and the clustering coefficient of the target was determined. Lastly the risk of water and mud inrush in Jigongling Tunnel was evaluated using the model. The results, which showed that the risk of water and mud inrush in target D1, D2 and D3 was respectively medium, extremely high and high, were compared with the excavation data. The two coincided with each other well which indicated that the model had a certain engineering value and could provide reference for related engineering.

      Abstract: Abstract In order to efficiently utilize meteorological drought indices, meteorological variables were compared with drought characteristics from the widely known Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI). The results of this study indicate that SPI overestimated drought severity and SPEI overestimated drought frequency and length under the same weather conditions. For droughts of high severity and short duration, the shortage of precipitation was the dominant cause for the occurrence of drought. For investigation on drought duration, it was revealed that precipitation was the dominant variable influencing droughts at short durations. The effect of precipitation on drought decreased at long durations, with the effect of Potential Evapotranspiration (PET) on drought became important. For investigation on drought severity, it was revealed that drought severity was proportional to precipitation in both SPI and SPEI, but other meteorological variables did not have a significant relationship with drought severity. These results mean that the magnitudes of the two drought indices changes in different meteorological regimes and it is possible to contribute to the quantitative decision and the combination of drought indices for meteorological drought.

  • Assessment of Roughness Coefficient for Meandering Compound Channels
    • Authors: Arpan Pradhan; Kishanjit Kumar Khatua
      Pages: 2010 - 2022
      Abstract: Abstract Factors affecting roughness coefficient in a meandering compound channel are investigated and used to predict Manning’s roughness by dimensional analysis. Factors affecting Manning’s roughness, are considered to be geometric as well as hydraulic, namely relative depth of flow, width ratio, bed slope and sinuosity for a meandering compound channel. An experimental investigation was carried out for the highly meandering channel of sinuosity 4.11. Observations of various researchers, on the laboratory study of meandering channels have also been used in the investigation. The proposed equation for predicting composite Manning’s roughness is used to estimate the conveyance of a channel with floodplain flow. The proposed dimensional analysis model is observed to predict the conveyance capacity better than other existing methods of Manning’s n prediction.

    • Authors: Shams-Ul-Islam; Raheela Manzoor; Umar Khan; Ghazala Nazeer; Sehrish Hassan
      Pages: 2023 - 2034
      Abstract: Abstract A two-dimensional numerical simulation for flow over a main cylinder with detached controlling cylinders placed at different position is performed through Lattice Boltzmann Method (LBM) to reduce fluid forces. For this study the Reynolds number (Re) is fixed at 160, while gap ratio between these cylinders are taken in the range from 0.5 to 8. The results yield in terms of vorticity, time-series analysis of drag and lift coefficients, power spectra of lift coefficients and force statistics. Depending on gap spacing, flow is classified into four different patterns, called as (i) single blender body, (ii) shear layer reattachment, (iii) fully developed flow and (iv) vortex suppression fully developed flow patterns. In comparison of all three configurations, it is examined that the maximum value of Cdmean and Strouhal number occurs for downstream configuration. Whereas, upstream and dual configuration play a vital role to reduce forces and to suppress vortex shedding. The maximum reduction found in mean drag coefficient for downstream, upstream and for dual configuration is 8.3%, 51% and 50.8%, respectively. Whereas, the reduction in Clrms values for all three configurations is 84.4%, 58.2% and 86.4%, respectively.

  • A Cooperative Use of Stochastic Dynamic Programming and Non-Linear
           Programming for Optimization of Reservoir Operation
    • Authors: Mohsen Saadat; Keyvan Asghari
      Pages: 2035 - 2042
      Abstract: Abstract Stochastic Dynamic Programming (SDP) is a conventional procedure to extract optimal reservoir operating policies. SDP applies exhaustive search based on the total combinations of discrete values of state variables. The accuracy of SDP can be improved by increasing the number of intervals of inflow or reservoir volume domain; however, increasing the inflow intervals is limited and increasing the reservoir volume intervals does not guarantee the regular improvement of results. This study attempts to determine the near optimum discrete reservoir volume values by cooperating SDP and non-linear programming (CSDP) optimization modules, so the acceptable performance is achieved by limited intervals of the state variables. Towards this end, the objective function is utilized with a hedging policy to control the amount of the monthly reservoir release. The non-linear programming optimization module embodied in SDP, determines the proper values of reservoir volume taking into account the hedging policy and available constrains. Considering various numbers of inflow and reservoir volume intervals, the conventional SDP results are implemented and compared to CSDP approach. Our comparisons indicate an improved reliability performance obtained in the CSDP technique. A Distance Based Interpolation Formula (DBIF) is also illustrated and applied to employ optimal operating polices for reservoir operation management. Findings show better performance of DBIF as compared to conventional methods like Multiple Linear Regression (MLR) during long-time simulation of reservoir operation.

  • Traffic Flow Assignment Model with Modified Impedance Function
    • Authors: Yuan-Yang Zou; Xue-Guo Xu; Yu Hu; Gui-Hua Lin
      Abstract: Abstract In this paper, we study a mixed-mode traffic network, in which Battery Electric Vehicles (BEVs) and Gasoline Vehicles (GVs) can be driven freely. We propose a new piecewise impedance function and, based on this new impedance function, we present a convex but nonsmooth optimization model for the traffic network. In order to deal with the nonsmoothness, we introduce a binary variable. Furthermore, we report some numerical examples to show the efficiency of the model. %is effective and robust. In particular, our numerical results illustrate that, if the distance limit of BEVs is long enough and the unit operating cost of BEVs is lower than GVs, more travelers prefer to choosing BEVs.

  • Numerical Study on the Ultimate Behavior of Elastomeric Bearings under
           Combined Compression and Shear
    • Authors: Tong Zhou; Yi-Feng Wu; Ai-Qun Li
      Abstract: Abstract Predicting the ultimate behavior of elastomeric bearings subjected to combined compression-shear loading is an indispensable part of quantitatively evaluating the performance of seismic isolated structures during earthquakes. In this paper, the initial critical load derived from three different approximations for bending modulus are analyzed and evaluated by existing experimental data. Then, Finite Element (FE) models of bearings are developed and validated by critical load results. Based on that, a parametric FE study is performed to investigate the failure mode of bearings under this combined loading. It is demonstrated that the bending modulus based on the pressure solution and further simplification provides a more reasonable estimate of initial critical load. The predicting capacity of the overlapping area method for the general trend of critical load is improved with the increasing of external diameter. The dividing line between stability limit and shear failure is dominated by the second shape factor. Furthermore, as the first shape factor increases, the ultimate shear deformation corresponding to shear failure slightly increases.

  • Buildings Vulnerability Assessment and Damage Seismic Scenarios at Urban
           Scale: Application to Chlef City (Algeria)
    • Authors: Zohra Boutaraa; Caterina Negulescu; Ahmed Arab; Olivier Sedan
      Abstract: Abstract Seismic scenarios are tools used to assess seismic risk at the city level. This allows the assessment of the vulnerability of exposed elements to risk (buildings, bridges, etc.). In the case of Chlef city (formerly El Asnam), this evaluation type proves to be useful given the seismic hazard to which it is exposed and the building park size. This city has been shaken in the past by several earthquakes including that of the El Asnam 1980 (Ms = 7.3), which caused hundreds of casualties and destroyed 70% of the city. In this paper, a seismic vulnerability assessment at urban scale and three seismic damage scenarios are simulated using the “RISK-UE” methodology. First, a recreation of the El Asnam 1980 earthquake, considering the urban conditions of the 1980s, is done. A difference of about 12% between observed and simulated damage is observed. Secondly, two senarios considering the current urban conditions are simulated then, vulnerabilty curves are developed. The simulations purpose is to detect the most vulnerable typologies and districts in the event of a similar earthquake and to provide decision support elements to the local seismic risk manager. The results show a structural damage decrease compared to the 1980 urban conditions.

  • Tightening Torque Influence on Pullout Behavior of Post-installed
           Expansion Anchors
    • Authors: Fabien Delhomme; Bertrand Pallud; Nicolas Rouane
      Abstract: Abstract Post-installed anchors in reinforced concrete structures are increasingly important in current constructions especially in repair or upgrading works. A research program was completed to determine the influence of the tightening torque and the anchorage depth on the pullout performances of torque-controlled expansion anchors. The diameter d of the tested anchors was 10 mm. Six configurations were tested on 18 concrete blocks. Three pre-tension loads and two anchorage depths were considered. The results show that the fastening torque has no influence on the load-bearing capacity far away from the edges. However, an increase of the torque leads to a decrease of the anchor’s slipping during pullout tests. Nevertheless, applying an excessive fastening torque may lead to a steel-rupture of the anchor during the fastening phase. An increase of the anchorage depth leads to a better load capacity of the anchor and reduces the risk of concrete cone rupture. Finally, a simplified model of the tension response of the anchor with a bilinear load-displacement relationship has been suggested.
