摘　　要：为研究平面不规则异形柱框架结构的抗震性能,本文以实际工程为背景,按照等刚度原则建立异形柱框架与矩形柱框架结构计算模型。运用PKPM有限元程序对计算模型进行弹性及弹塑性静力计算分析,从而计算出两种结构的弹性位移、扭转系数及结构的抗倒塌性能等结构抗震性能指标。结果表明,L型平面不规则异形柱框架结构在7度(0.15g)抗震烈度l/b max、l/b及高度超限的情况下仍然具有较好的抗震性能,且优于等刚度矩形柱框架结构。In order to research the seismic behavior of specially shaped columns frame structure of L - shape, this paper establishes specially shaped and same stiffness rectangular column frame structure model based on an actual project. This paper used PKPM software to calculate the models of elastic and elastic - plastic behavior and to get the elastic displacement, tensional coefficient and the collapse of the performance of the structures. The results showed that specially shaped columns frame structure of L - shape had a good seismic behavior under 7 degrees （0.15g） ground, also were better than the rectangular column frame structure seismic behavior.
