山东国际会展中心展馆结构设计

Structural design of exhibition hall of Shandong International Convention and Exhibition Center

山东国际会展中心一期项目包含了1~5号展馆、共享大厅、卸货平台和地下车库四部分。地上总建筑面积226240m^(2)。其中,1号展馆为国内首个3层的会展中心展馆,结构类型为钢框架-支撑结构+大跨度空间钢结构,其余展馆为钢框架结构+大跨度空间钢结构,展馆楼面均采用箱形截面主次桁架的结构形式,屋盖采用倒三角空间管桁架,最大建筑高度为49.75m(室外地面至曲面屋面中心线),最大跨度达70m。对展馆部分工程概况、结构体系、主体结构设计及结构性能分析等方面内容进行了阐述,并将波纹腹板(曲线形腹板)H型钢应用于结构设计。

The first phase of the Shandong International Convention and Exhibition Center includes four parts:No.1~5 exhibition halls,shared halls,unloading platforms and underground garages.The total construction area on the ground is 226240 m^(2).Among them,No.1 exhibition hall is the first three-story convention and exhibition center in China.The structural type is steel frame-supporting structure+large-span spatial steel structure.And the rest of the exhibition halls adopt steel frame structure+large-span spatial steel structure.The floor of the exhibition hall adopts a primary and secondary truss structure with box-shaped sections,and the roof adopts an inverted triangular spatial tube truss with the maximum building height of 49.75m(from outdoor ground to the centerline of the curved roof)and the maximum span of 70m.The project overview,structural system,main structural design and structural performance analysis of the exhibition halls were elaborated,and the corrugated web(curved web)H-shaped steel was applied to the structural design.
