［摘要］为了给上海市装配整体式叠合剪力墙结构技术规程的编制提供科学依据，基于上海某双面叠合剪力墙结构住宅，通过动力弹塑性分析方法，对比研究了水平缝对双面叠合剪力墙结构基底剪力、顶点位移、层间位移角和构件损伤的影响。分析结果表明，多遇地震下的结构分析计算可以不考虑水平缝的影响；结构1层水平缝在罕遇地震下成为薄弱部位；通过1层现浇或1~2层水平缝强连接，可以有效解决1层水平缝薄弱问题。

Abstract:In order to provide a scientific basis for the compilation of technical specification  for monolithic precast concrete composite superimposed shear wall structure in Shanghai, based on a superimposed shear wall structure residence in Shanghai, through dynamic elastic plastic analysis method, the influences of horizontal seams on the base shear force, the vertex displacement, story drift ratio and the component damage of the superimposed shear wall structure were studied. Analysis results show that the influence of horizontal seams can be not considered in the analysis of structures under frequently occurred earthquake; the first floor horizontal seams of the structure are weak parts under rarely occurred earthquake; the weak problem of first floor horizontal seams can be effectively solved through casting in suit of first floor or the strong connection of first to second floor.

Keywords:superimposed shear wall structure; horizontal seam; seismic behavior; story drift ratio; dynamic elastic plastic analysis
