石家庄国际会展中心多功能厅结构设计

摘要
石家庄国际会展中心多功能厅跨度120m,局部大悬挑,采用钢管混凝土柱-大跨度折板网架屋盖结构体系,整体结构较为复杂。针对该结构进行了不同荷载组合下的受力分析,包括恒、活荷载、风荷载以及温度作用和地震作用等,重点分析整体结构的变形与应力情况;另外还对整体结构进行了中震弹性和Pushover分析。分析结果表明:结构体系安全可靠,结构整体抗震性能良好。
The multifunctional hall of Shijiazhuang International Convention and Exhibition Center is a long-span steel structure,of which the largest span reaches 120m.In order to achieve the large cantilever and long span demand of architectural presentation,a relatively complicated structure form,that is the steel-tube concrete column-folded network,has been adopted for the roof.During the structural design procedure,various load combinations have been analyzed,and the deformation and stress distribution of the structure have been checked.In addition,elastic design analysis under intermediate earthquake and Pushover analysis have been conducted for the structure.The analysis results show that the structural system is safe and reliable and has a good seismic performance.
