摘　　要：为了研究钢筋混凝土异形柱框架结构的抗震性能,对三榀三层两跨异形柱框架进行了拟静力试验,并采用静力弹塑性分析方法对试验框架进行了理论分析和计算,结果表明这三榀异形柱框架均具备良好的抗震性能.通过对三榀框架之间的对比分析,提出了有益于改善异形柱框架抗震性能的建议.所建立的静力弹塑性分析模型可用于钢筋混凝土异形柱框架的抗震性能评估.To study the seismic performance of reinforced concrete （RC） special-shaped-column frames, the pseudo-static test of three two-bay and three-story RC special-shaped-column frame specimens was conducted and the experimental frames were theoretically analyzed with pushover method. The result shows that these three frame specimens bave qualified seismic performance. And by the comparison among the three frame specimens, the method of improving the frames＇seismic performance was proposed. The proposed model of nonlinear static analysis can be used to evaluate the seismic performance of the RC special-shaped-column frames .
