神农大剧院螺旋形外壳钢结构设计
|
摘要
神农大剧院外形类似旋转螺壳,外壳主体结构采用螺旋形类拱壳空间钢结构。介绍了外壳结构方案的构思过程,结构体系的选型、优化以及其基本构成;还详细阐述了恒、活、地震、风、雪及温度等荷载作用的取值,整体结构的静力、动力反应及整体稳定分析结果。分析结果反映了结构性能的螺旋渐进变化的特征,证明了主体结构布置能够满足各种设计荷载作用下的性能要求。
Shennong Theatre is characterized by its elegant spiral-shaped outer shell.A spiral and spatial steel truss system was employed for the outer shell of the building.The incubation process of the structural scheme,its optimization and composition were introduced.The dead and live loads or actions due to earthquake,wind,snow and temperature etc.were elaborated.The results of the static and dynamic structural responses,the buckling characteristics and the predicted load capacity of the structure under dual nonlinearity of both geometry and material conditions were also presented.Study results reveal the spiral characteristics of the behavior of the main structure.Performance demands under all design loads were proved to be satisfied.
