摘　　要：为满足建筑工业化的迫切需求,进一步拓展钢框架-钢板墙结构和钢管混凝土柱-钢梁框架结构2种典型结构体系在高烈度区的应用,以某高烈度地区保障性住房建设项目为结构方案原型,分别对其进行多遇地震下的反应谱抗震设计,并补充了弹性动力时程分析验算,同时对比分析了罕遇地震下2种结构的弹塑性抗震性能。结果表明,钢框架-钢板墙结构体系在地震作用下的侧移模式呈弯曲型,塑性铰主要出现在钢板墙附近的梁端和柱端,而钢管混凝土柱-钢梁框架结构体系侧移模式呈剪切型,塑性铰主要出现在结构中间层的梁端。2种结构体系均能够满足预期的抗震设计要求,适用于高烈度区的多高层民用建筑。To address the pressing demands of industrialized construction and to broaden the application of two prominent structural systems,namely,the steel frame-steel plate wall structure and the steel frame structure with concrete-filled steel tube columns,in high-intensity regions,a high-intensity area affordable housing construction project was taken as a prototype.This involved seismic design based on frequent earthquake response spectra and supplemented by elastic dynamic time history analysis.At the same time,a comparative analysis of the elastic-plastic seismic performance of these two structural systems under rare earthquake scenarios was conducted.The results show that the steel frame-steel plate wall structure system exhibits a bending-type lateral deformation pattern,with plastic hinges predominantly forming at the beam and column ends near the steel plates during earthquakes.Conversely,the steel frame structure with concrete-filled steel tube columns displays a shear-type lateral deformation pattern,with plastic hinges primarily forming at the beam ends on intermediate floors.Furthermore,both structural systems meet the prescribed seismic design requirements,rendering them suitable for application in high-rise civil buildings within high-intensity areas.
