摘　　要：经典结构力学中求解超静定刚架的方法非常多,但实际工作中主要还是采用结构力学仿真进行计算,只是目前对仿真结果的正确与否很难判断,定性结构力学可以通过估算某些截面处的弯矩,速画M图的大体轮廓,比较某几处杆端弯矩的大小,来实现对结构力学仿真结果的判断,对超静定刚架进行的定性分析示例可以促进定性结构力学内容体系的建立。There are many means to solve statically indeterminate frames in classical structural mechanics.And it takes too much time to study these means for the students.But most of them are not adopted in practice.The most commonly used is structural simulation technology.Whether the results of the simulation are correct or not is hard to judge at present.However qualitative structural mechanics can complete this task,by the estimation of the bending moments on some cross sections and the moment outline of the whole structure and the comparison among some rod-end moments.The examples of qualitative analysis of statically indeterminate frames in paper would be beneficial to the establishment of content system in qualitative structural mechanics.
