［摘要］為了給上海市裝配整體式疊合剪力墻結(jié)構(gòu)技術(shù)規(guī)程的編制提供科學(xué)依據(jù)，基于上海某雙面疊合剪力墻結(jié)構(gòu)住宅，通過(guò)動(dòng)力彈塑性分析方法，對(duì)比研究了水平縫對(duì)雙面疊合剪力墻結(jié)構(gòu)基底剪力、頂點(diǎn)位移、層間位移角和構(gòu)件損傷的影響。分析結(jié)果表明，多遇地震下的結(jié)構(gòu)分析計(jì)算可以不考慮水平縫的影響；結(jié)構(gòu)1層水平縫在罕遇地震下成為薄弱部位；通過(guò)1層現(xiàn)澆或1~2層水平縫強(qiáng)連接，可以有效解決1層水平縫薄弱問(wèn)題。

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
