摘要
首先采用有限元法对水平和竖向波形钢板剪力墙试件进行了数值模拟,并与试验所得破坏特性和滞回曲线进行了对比,验证了有限元模型的有效性。通过数值模拟对采用方钢管作为边缘柱的波形钢板剪力墙进行了分析,对比分析了水平和竖向波形钢板剪力墙的抗震性能。通过试验破坏现象和数值模拟得到以下结论：方钢管柱在水平往复荷载作用下能抑制钢板剪力墙的失稳,有利于内置波形钢板承载能力和塑性变形耗能能力的发挥;水平波形钢板剪力墙比竖向波形钢板剪力墙有更高的承载力,滞回曲线更加饱满,塑性变形范围、延性和耗能能力也更好,且构件达到峰值荷载后仍有较大的承载力储备。通过试验破坏现象和数值模拟分析结果,针对波形钢板剪力墙的应用提出了加强边缘约束构件刚度的建议。
Based on the lateral performance of corrugated steel plate shear wall,the finite element numerical simulations of horizontal and vertical corrugated steel plate shear wall specimens were carried out. The validity of the finite element model was verified by comparing the failure characteristics with the hysteretic curves of experiment. Numerical simulation analysis of corrugated steel plate shear wall with square steel tube as edge column was performed to compare and analyze the seismic behavior of horizontal and vertical corrugated steel plate shear walls. The following conclusions were obtained by experimental failure phenomena and numerical simulations： square steel tube column could inhibit the buckling of steel plate shear wall under the action of horizontal cycle loading,and is beneficial for corrugated steel plate to improve the flexual and shear bearing capacities and plastic deformation energy dissipation. Compared with vertical corrugated steel plate shear wall,the horizontal corrugated steel plate shear wall has higher bearing capacity,its hysteresis curve and plastic deformation range were more plump,ductility and energy dissipation capacities were better,and the bearing capacity reserve was still sufficient after the member reached the peak load. Some suggestions such as improving the stiffness of constraint edge component on the design and application of corrugated steel plate shear wall were put forward by analyzing the failure phenomena and numerical simulation results finally.
