[提要]  为了解框架结构在超过弹性阶段的工作性能和破坏特征，可采用伪静力试验和静力弹塑性分析两种不同的方法。对两层两跨异型柱框架结构进行静力弹塑性分析以尽可能多地获取伪静力试验中所能得到的数据，并将计算结果和伪静力试验结果作了对比分析。

Pseudostatic experiment method and nonlinear static analysis method are often used to evaluate the working performance and the destroying characteristic of a frame structure being on nonlinear working stage.A two-bay and two-storey hetero-columns frame is analyzed with push-over method to acquire the results which can be received by pseudostatic experiment as many as possible. The results acquired by push-over method are analyzed and contrasted with those got by pseudostatic experiment.
Keywords:  nonlinear static analysis; push-over method; M- φ curve;  hetero-columns frame
