摘要

按现行规范及技术规程设计了设防烈度为8度的一个不规则的钢筋混凝土异形柱框架结构，并进行了双向水平地震作用下的空间三维非线性地震反应分析，考查了异形柱框架结构在罕遇地震水准下的整体抗震性能，对结构能否达到抗震设防目标进行了初步评价。结果表明，8度区按规范设计的结构在罕遇烈度地震作用下基本能够达到预期的抗震设防目标。

Abstract

According to the code and technical regulation

an irregular RC frame with specially shaped columns has been designed

which situated at the area of fortification intensity 8. Subsequently

the nonlinear dynamic analysis has been carried out for the structure by inputting ground motions in two directions. After summing up the calculation results

this paper has examined seismic performance of the structure under the rare seismic actions and given a primary evaluation on the structure to see if it could achieve the predetermined anti-seismic aims. It indicates that the structure designed according to the codes can achieve the predetermined anti-seismic aim under the rare earthquake.
