局部设缝短肢剪力墙静力弹塑性分析

Pushover analysis of short-leg shear wall with local slit

针对底部设缝与传统不设缝短肢剪力墙,对静力弹塑性进行了分析,表明在剪力墙底部塑性铰区域设置竖缝后,破坏形式及变形能力均发生了改变,设缝后墙体塑性铰区域增大,结构延性得到了提高,并且结构抵抗水平作用的能力有所加强,抗震性能得到了改进.

In this paper, based on the short shear wall with slit at the bottom and traditional with no slit, pushover analysis of the structures has been conducted. The results show that after the bottom plastic hinge area of the shear wall set the vertical slit, the failure forms and deformation capacity of the structure may be changed, the plastic hinge region has increased of the shear wall with slit, and ductility of structure has improved. Besides, the capacity of resistance horizontal load has been slightly strengthened. Therefore, seismic performance may be better.
