某多层 RC 框架和支撑-钢框架抗震性能分析

摘要

结合工程实例，采用软件 SAP2000对 RC 框架和支撑-钢框架结构抗震性能进行了抗震性能分析，结果表明：支撑-钢框架侧移刚度要大过 RC 框架，在罕遇地震作用下出现塑性铰少，优化支撑后的钢框架，地震能量绝大部分被支撑所耗散。%Combining with project example,use software SAP2000 analyze the seismic performance of Reinforced Concrete frame structural sys-tem and steel structure with bracing frame structures,the results showed that:less rare appearance in the case of earthquakes under the plastic hinge,better seismic performance. After optimization of supporting steel frame structure,the vast majority of rare earthquake energy is dissipated by plastic deformation of the support.
