摘要
在分析钢筋混凝土斜撑框架结构和错列框架剪力墙结构的抗震性能的基础上,提出错列支撑框架结构。为研究错列支撑框架结构抗震性能,分别对5种不同类型的结构采用ANSYS软件进行结构动力特性、地震反应谱位移响应、地震时程位移响应求解。通过比较分析,得出错列支撑框架结构具有良好的抗震性能及广阔的应用前景。还比较了按反应谱分析的结果和按振幅折减典型El Centro波进行时程分析的结果,得出进行地震时程分析时选用地震波的原则。
Based on the analysis of seismic performance of bracing reinforced concrete frame structure and the staggered frame shear- wall structure, propose the staggered bracing frame structure. In order to study on seismic performance of staggered bracing frame structure,choose 5 different structural types and used ANSYS to analysis the dynamic characteristics, displacement response using spectrum method, displacement response using seismic time history solution. Through analysis and comparison, we can see the staggered bracing frame structure has good seismic performance, broad application prospects. Also compared the response spectrum analysis and amplitude reduced by a typical E1 Centro wave time history analysis,obtained some note for seismic time-history analysis.
