摘要
钢框架在地震作用下的非线性行为非常复杂,影响因素众多,其非线性分析一直是结构工程中的研究热点。根据非线性分析方法选取的最小子结构的不同,对目前常用的钢框架非线性分析方法进行分类,归纳为5种分析方法。通过对这些方法的操作流程进行比较分析,并对已有相关研究进行总结,表明每种方法都有其固有的优点和不足。在实际分析时,应根据具体情况选择合适的分析方法。
The nonlinear behavior of steel frame under seismic loading,as a research focus in structure engineering field,is uncommonly complicated due to a large number of influence factors. According to different minimum substructures,commonly used nonlinear analysis methods for steel frame structures were classified into five categories.Through the comparative analysis of the operation flow,and the summary of relevant studies of each method,the advantages and disadvantages of each method were concluded. It is indicated that,in practical analysis,a specific appropriate method should be chosen according to different situation.
