摘　　要：基于GB 50017—2003《钢结构设计规范》和现行GB 50017—2017《钢结构设计标准》提出的一种二阶弹性分析的近似方法,构建了两个典型框架模型,并与有限元计算结果对比,分析了该近似方法的准确性和对于不同框架结构的适用性。Based on GB 50017-2003 Code for Design of Steel Structures and the current GB 50017-2017 Standards for Design of Steel Structures, an approximate method of second-order elastic analysis is proposed,and two typical frame models are constructed, Comparing the finite element calculation results, the accuracy of the approximation method and its applicability to different frame structures are analyzed.
