钢框架-钢板墙和钢管混凝土柱-钢梁框架结构抗震性能对比分析

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。

Comparative analysis of seismic performance for steel frame-steel plate wall structure and steel frame structure with concrete-filled steel tube columns

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.
