摘　　要：通过对2榀由两个"L"形与一个"T"形截面柱组成的非对称混凝土框架结构进行低周反复加载试验,对试验现象、破坏特征、滞回曲线和变形性能等进行描述和分析。分析结果表明:2层混凝土异形框架结构具有良好的抗震性能。此外,还使用大型有限元分析软件MARC进行了数值模拟分析,对结构进行了骨架曲线、塑性铰出现顺序的计算分析,结果与试验吻合较好。Low-cyclic loading tests were made on two RC frame structures, each of which was made up of two ＂L＂ section and one ＂T＂ section columns. Several aspects, such as the test phenomena, failure characters, hysteretic curves and deformation performances, are described and analyzed. Analysis result shows that 2 story RC frame structure has good seismic performances. Besides, nonlinear analysis software MARC is used to simulate the framework curve and the sequence of plastic hinges, the results of the analysis have good coincidence with those of the tests.
