摘　　要：本文按现行规范及技术规程设计了设防烈度为8度的一个规则的钢筋混凝土异形柱框架,并进行了单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设防和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设防烈度及罕遇烈度地震作用下基本能够达到预期的抗震设防目标。According to the code and technical regulation, a regular RC frame with special-shaped columns was designed, which was situated at the area of fortification intensity 8. Subsequently, the nonlinear dynamic analysis was carried out for the structure by inputting ground motions in one direction. The seismic performance of the structure under fortication and rare seismic actions was examined and whether the structure achieved the predetermined seismic aims was evaluated. The results indicate that the structure designed according to the codes can achieve the predetermined seismic aims under fortification and rare seismic actions.
