总装分析对大跨空间结构设计的重要性

揭示了传统的大跨空间结构上下部结构单体设计方法存在的安全隐患,传统方法既不能反映上部结构刚度对整体结构的贡献,也不能反映下部结构有限刚度对上部结构的效应放大;提出了总装分析整体结构的设计计算方法.通过济南奥林匹克中心体育场为实例的总装分析与单体分析结果对比,证明整体结构总装分析能够得到上下部结构在重力、风、地震、温度作用下较为合理可靠的效应,尤其能揭示连接界面结构构件的不利受力状态.整体结构总装分析的理念与方法对大跨空间结构的设计具有重要意义,可供类似工程设计参考应用.

Importance of whole structural analysis in long-span structural design

This paper explores that the traditional method analyzing the super steel structure & sub RC structural separately in long-span structure exists safety trouble.The traditional method can't take account of the stiffness contribution of super steel structure to the whole structure and the effect on the super steel for the limited stiffness of sub RC Structure.This paper proposes a new method analyzing the whole structure including super steel structure and sub RC structure under the action of gravity,wind,ear...
