Experimental investigation of composite shear panels under cyclic loading

The paper reports the experimental investigation of composite shear panels, composed of steel columns incorporated in concrete panels by means of headed shear studs, under reversible cyclic loading. Results are presented for push-out tests on small specimens and for whole panels. The response of two composite panels is compared to that of a conventional reinforced concrete panel of similar design parameters, serving as control. The results indicate that while ductility of the composite panel with unmodified connection is somewhat lower than that of the control panel, damage to the panel is substantially reduced. Composite panel with voids at studs’ roots displays enhanced ductility and energy absorption capacity. Other means of enhancing these parameters are discussed. An approximate, simplified analytical model based on push-out tests, yields a good qualitative prediction of panel response with conservative values of capacity, ductility and energy absorption.

Thermal Performance of Composite Panels Under Fire Conditions Using Numerical Studies: Plasterboards, Rockwool, Glass Fibre and Cellulose Insulations

In recent times, light gauge steel frame (LSF) wall systems are increasingly used in the building industry. They are usually made of cold-formed and thin-walled steel studs that are fire-protected by two layers of plasterboard on both sides. A composite LSF wall panel system was developed recently, where an insulation layer was used externally between the two plasterboards to improve the fire performance of LSF wall panels. In this research, finite element thermal models of the new composite panels were developed using a finite element program, SAFIR, to simulate their thermal performance under both standard and Eurocode design fire curves. Suitable apparent thermal properties of both the gypsum plasterboard and insulation materials were proposed and used in the numerical models. The developed models were then validated by comparing their results with available standard fire test results of composite panels. This paper presents the details of the finite element models of composite panels, the thermal analysis results in the form of time–temperature profiles under standard and Eurocode design fire curves and their comparisons with fire test results. Effects of using rockwool, glass fibre and cellulose fibre insulations with varying thickness and density were also investigated, and the results are presented in this paper. The results show that the use of composite panels in LSF wall systems will improve their fire rating, and that Eurocode design fires are likely to cause severe damage to LSF walls than standard fires.     

外挂PC复合墙板的分层装配支撑钢框架足尺振动台试验研究

为真实反映地震作用下墙板与分层装配支撑钢框架的动力协同工作性能,设计了三层足尺分层装配支撑钢框架通过柔性减震连接件外挂PC复合墙板结构模型,通过振动台试验考察其动力损伤演化机制和变形特征。研究结果表明：外挂PC复合墙板的分层装配支撑钢框架结构可以满足我国规范对于抗震安全性的要求,并且表现出损伤控制和低残余位移特性。多遇地震作用下结构和墙板完好无损;设防地震作用下结构无损,墙板微损;罕遇地震作用下结构损伤集中于柔性支撑,梁柱框架无损,墙板及连接无显著破坏;超大地震作用下梁翼缘局部进入塑性,墙板节点和墙板边缘及预埋件处有显著破坏但主体结构完好。采用柔性减震连接件外挂的PC复合墙板不会影响分层装配支撑钢框架的变形恢复能力,其相对于主体结构具有良好的变形适应性,提高了分层装配支撑钢框架的层间变形均匀性,在支撑松弛的情况下可以显著提高结构刚度,从而降低层间位移响应和扭转响应,并削弱了柔性支撑在动力作用下突然张紧产生的冲击效应。总体上,外挂PC复合墙板的分层装配支撑钢框架结构具有优良的抗震性能和震后可恢复性。     

带暗梁柱的开洞混凝土复合墙板受弯和偏压性能足尺试验研究

针对带窗洞复合墙板受弯与受压承载力不足的问题，提出了一种带框复合墙板，即通过在复合墙板内设置暗梁、暗柱来提高其承载力。对5块足尺的带窗洞复合墙板进行四点弯曲试验和偏心受压试验，考察其破坏模态和承载能力。试验结果表明，复合墙板的抗弯刚度较高，受弯荷载满足由美国ASCE/SEI 7-05规范计算得到的关岛风荷载设计值要求；在四点弯曲荷载和偏心受压荷载作用下，复合墙板能实现完全组合作用，两侧混凝土面层变形协调，符合“平截面假定”；复合墙板在四点弯曲荷载下发生延性破坏。分别按美国ACI 318M-05《混凝土结构设计规范和注释》和中国GB 50010—2010《混凝土结构设计规范》对复合墙板的受弯承载力进行了计算，计算值与试验值误差最大不超过16%，并且利用两种规范公式计算得到的承载力均较为保守。     

Steel–concrete composite shear walls using precast high performance fiber reinforced concrete panels

In this research, seismic performance of composite steel plate shear walls (CSPSWs) using high performance fiber reinforced concrete (HPFRC) panels is experimentally and numerically investigated. Three one‐story one‐bay CSPSW specimens using precast HPFRC panels were designed and fabricated for cyclic quasi‐static experiments. The HPFRC panels of composite shear wall specimens did not have any steel rebars. The main purpose of the study was to understand the effects of rigid and semirigid HPFRC panels on the seismic behavior of the system. Shear capacity, ultimate shear strength, lateral stiffness, energy dissipation, and ductility ratios of the specimens are evaluated. The experimental results demonstrate that specimens were able to resist lateral load up to at least interstory drift of 6%. Using HPFRC panels, CSPSW specimens becomes stiffer in the elastic region, and the yield displacement of the shear wall is decreased; therefore, the ductility ratio of the system is increased. It should be noted that ultimate shear strength, initial elastic stiffness, and energy absorption of specimens with an HPFRC panel on one side or both sides of the infill steel plate were approximately the same. However, using two HPFRC panels is not economical in comparison with CSPSW with an HPFRC panel on one side. Additionally, the second panel increases the seismic mass of the structure.
