Abstract Corrugated steel plate shear wall (CSPSW) is one of the new structural systems used to resist earthquakes and that has better a hysteretic behavior than a flat plate shear wall. In this paper, three full-scale, single-story, single-bay specimens, consisting of one semi-rigid frame without infill panels and two semi-rigid frames with unstiffened and stiffened doubly trapezoidal corrugated plates, were subjected to cyclic loading. The hysteretic behavior and energy dissipation capacity of the three specimens were compared. The experimental results revealed that the corrugated plate greatly enhanced the stiffness and lateral load-carrying capacity of the semi-rigid frames. Therefore, the frames with the corrugated plates had higher energy dissipation capacity than the frame without infill panels. Moreover, the strength, stiffness and energy dissipation capacity of the stiffened corrugated specimen were greater than those of the unstiffened corrugated specimen, although the ductility of the stiffened corrugated specimen was lower. A method of calculating the lateral capacity of CSPSWs was proposed based on the superposition principle. This method could accurately predict the lateral capacity of the corrugated specimens.

波纹板半刚性框架滞回性能试验研究

摘要 波纹钢板剪力墙(CPSSW)是一种新型抗震结构体系,其滞回性能优于平板剪力墙。在本文中,三个全尺寸、单层、单开间试件,由一个没有填充板的半刚性框架和两个带有未加筋和加筋双梯形波纹板的半刚性框架组成,受到循环荷载。比较了三个试样的滞后行为和能量耗散能力。试验结果表明,波纹板大大提高了半刚性框架的刚度和横向承载能力。因此,具有波纹板的框架比没有填充板的框架具有更高的能量耗散能力。而且,实力,加筋波纹试件的刚度和耗能能力大于未加筋波纹试件,但加筋波纹试件的延展性较低。提出了一种基于叠加原理的CSPSWs侧向承载力计算方法。该方法可以准确预测波纹试样的横向承载力。
