摘　　要：对几类典型的不规则有侧移钢框架进行了一阶和二阶弹性分析,采用有限元方法得到了框架的二阶精确分析结果,并与现行《钢结构设计规范》(GB50017-2003)给出的二阶分析近似方法的计算结果进行了比较,分析了不规则钢框架的二阶效应以及规范近似方法对不规则框架的适用性,分析结果可供设计人员参考。The first--order and second--order elastic analyses of several typical irregular sway steel frame structures were conducted. The calculated results between approximate second--order analysis by Chinese Code GBS0017 -- 2003 and accurate second--order analysis by the finite element methods were compared. The second--order effects of the irregular steel frames and the serviceability of the approximate methods were analyzed. And the analysis results could be consulted by designers.
