摘要
本文通过二阶弹塑性稳定分析的结果,对钢框架结构的'PΔ'效应进行了分析研究.指出了我国现行设计方法中存在的问题,并提出了以二阶分析为依据的设计方法.
According to the results of second order inelastic stability analysis,'P△' effect of steel frame in the stability limit is studied in the paper.It is pointed out that some problems existed in the current design method of our country,and then a design method based on the second order analysis is presented.
