Its' aim is to find the multistory multispan frame structure's plastic limit load (using stiffness increment variation method),and the plastic limit state of stress(or internal force) distribution and the formation of collapse mechanism.
该方法以寻找多层多跨框架结构的塑性极限荷载(采用增量变刚度法求解)、塑性极限状态时的应力(或内力)分布和所形成的破坏机构为目的。
