RESEARCH ON THE DYNAMIC PROPERTY AND EARTHQUAKE RESPONSE OF FRAME-CORE WALL HYBRID STRUCTURES IN HIGH SEISMIC INTENSITY REGIONS

简单介绍了高烈度区混合结构采用型钢混凝土框架—钢筋混凝土筒体的优势,针对高层结构对结构侧移敏感性的特点,并结合混合结构工程实用中常用的几种框架形式,采用SAP2000程序对一高烈度区典型型钢混凝土框架-钢筋混凝土筒体模型进行了有限元分析。研究了该结构体系的动力特性,并集中讨论了框架形式改变对其影响。最后,对该模型结构的地震位移及地震作用分布规律进行了讨论。可以为该类工程结构设计提供参考。

It is briefly presented the superiority of adopting steel reinforced concrete frame-reinforced concrete core wall structure in high seismic intensity regions.Aiming at the sensitivity to lateral displacement of high-rise structure and the several frame modes often adopted in hybrid structure,it is conducted finite element analysis to a steel reinforced concrete frame-reinforced concrete core wall model structure by program SAP2000.The dynamic property of structure is studied,and the influence on structure lateral displacement when the outer frame is in different joint form,beam type and column space is emphatically discussed.In the end,the lateral displacement rules and earthquake load distribution rules are discussed.Some conclusions are help for the design of this kind of structure.
