摘要
石家庄国际会展中心中央大厅长约800m,宽约100m,规模大、结构体系复杂。屋盖竖向支承体系由结构树和Y形柱两种结构形式组成,屋盖采用折板网架。介绍了结构选型及构件布置特点,给出了各种荷载取值及相应计算结果,并对结构设计中的一些关键问题进行了深入分析。通过弹塑性分析,详细分析了结构的抗震性能;研究了结构柱计算长度系数取值及节点受力情况。
The concourse of Shijiazhuang International Convention and Exhibition Center is a large and complex structural system, which is about 800m long and lOOm wide. The roof supporting system consists of two structural forms of tree and Y shape column, and folded plate space truss is used for roof. The choice of structure styles was introduced, the loads value and analytical results were given, and in-depth analysis on some key issues in structure design was carried out. Based on the elastic-plastic analysis, the seismic performance of the structure was fully studied, and the effective length factor of the columns and the node design were introduced.
