[摘要]錯(cuò)層結(jié)構(gòu)對(duì)抗震不利。結(jié)合一幢高烈度區(qū)的鋼筋混凝土剪力墻錯(cuò)層高層建筑,采用靜力彈塑性推覆分析以及動(dòng)力彈塑性時(shí)程分析方法,研究了結(jié)構(gòu)在設(shè)計(jì)小震、中震以及大震作用下的變形特征、構(gòu)件屈服機(jī)制及結(jié)構(gòu)破壞模式,揭示出結(jié)構(gòu)中可能存在的抗震薄弱部位,給出了結(jié)構(gòu)在罕遇地震作用下抗震性能的評(píng)價(jià),并提出了對(duì)同類工程結(jié)構(gòu)設(shè)計(jì)有益的建議。

Abstract:Staggered structures have disadvantages for aseismic engineering. Taking one shearwall high-rise structure with staggered floors as research object, the structure deformation behavior, yield mechanism and failure mode under frequent, middle and rare earthquakes were studied by using nonlinear static pushover analysis and elasto-plastic dynamic analysis methods. The weak parts were revealed and the aseismic performance was evaluated. Finally, some useful suggestions were proposed for the staggered structure design.
Keywords:high-rise structure; staggered floor shear-wall structure; aseismic performance; elasto-plastic
