【摘要】 总结了巨型钢框架结构三维非线性分析模型的发展现状,介绍了塑性铰模型、简化塑性区模型和有限分割塑性区模型在巨型钢框架结构中的应用,指出了它们的优缺点。为了实现高精度和高计算效率分析模型在巨型钢框架结构非线性分析中应用,讨论了纤维模型和三维壳单元模型,并简单概述了作者将这两种模型应用于巨型钢框架结构三维非线性分析的尝试性工作。
【Abstract】 In this paper,state of the art on three-dimension nonlinear analysis models of the steel mega-frame structures is summarized.The uses of the plastic hinge model,the simplified plastic zone model and the finite segment plastic zone model in the steel mega-frame structures are introduced,and their advantages and weaknesses are pointed out.In order to apply the analytical models with high computational efficiency and calculation accuracy to the steel mega-frame structures,the fiber model and the three-dimension shell element model are discussed.Finally the attempt to apply two models to the three-dimension nonlinear analysis of the steel mega-frame structures is discussed in brief.
