神农大剧院钢结构外壳与混凝土结构共同工作分析研究
|
摘要
神农大剧院采用上部大跨度空间钢结构外壳,下部混凝土结构。本文采用通用结构分析与设计软件SAP2000V14,分别建立了混凝土结构、钢结构外壳单独模型和混凝土结构与钢结构外壳整体模型进行分析。分析结果反映了上、下部结构的相互影响的程度,了解了在温度、地震作用下整体结构的反应以及连接界面结构构件的实际受力状态,验证了钢结构外壳和混凝土结构组成的大跨度空间结构体系单独设计存在的隐患。
The Shennong Grand Theatre adopts the structure of upper large-span space steel shell,and the lower part of concrete structure.This paper,by means of general structural analysis and design software SAP2000 V14,builds up separately the concrete structures model,the steel shell model,and the concrete structure and steel shell overall model.Analysis of the above reflects the degree of interaction of the upper and the lower parts of the structure,the reaction of the whole structure under the effect of temperature and earthquake,and the actual stress of the interface.The result reveals the hidden danger when the steel shell and concrete structure consisting of large span space structure are individually designed.
