摘要
利用有限元分析软件SAP2000建立了钢板剪力墙结构非线性模型,将结构地震非线性模拟分析结果与振动台试验结果进行对比分析,验证了建模方式的有效性;对比分析Ⅰ形开洞钢板剪力墙结构和四边连接钢板剪力墙结构在地震作用下的自振频率、位移响应、加速度响应以及塑性铰分布情况等,结果表明Ⅰ形开洞钢板剪力墙在结构整体中的等效性较好,能够较好地解决在振动台试验中缩尺钢板剪力墙厚度较小而无法制作的问题。
The nonlinear analytical model of a steel plate shear wall structure is established using the finite element analysis software SAP2000. The nonlinear simulation results are compared with the shaking table test, and effectiveness of the modeling method is verified. Seismic behavior of structure with Ⅰ-shaped steel plate shear wall and fully connected steel plate shear wall structure is analyzed and the response such the vibration periods, displacement, acceleration and plastic hinge distribution are compared. Some advices are proposed.
