【摘要】 铁岭体育馆工程是局部带有大悬挑平台的单层网壳结构工程。介绍了大跨度网壳的结构布置特点、静力性态分析、动力响应分析与非线性屈曲分析,同时给出鼓形节点的计算结果。结构前方有近7m的大悬挑平台且平台端部荷载较重,采用预应力悬挑梁+钢管混凝土斜柱方式承担大悬挑弯矩作用。分析方法、结果及设计方法可供类似结构的分析、设计参考。更多还原

【Abstract】 The Tieling Gymnasium is a steel single-layer shell structure with a large overhang platform.Designs of steel shell structure,the linear analysis,the dynamical response analysis,nonlinear stability analysis,the analysis result of shell structure joint are presented.There is a large overhang platform in this structure which is loaded with the steel shell structure.The bending of this platform is beared by steel tubular column and prestressed concrete beam.The analysis method and result can be taken as reference to similar structures.更多还原
