宁波国际会展中心屋盖管桁架结构设计
|
摘要
宁波国际会展中心的小展厅和东、西展厅大跨度屋盖采用了主、次空间管桁架结构体系 ,钢管之间直接相贯焊接。在展厅中部设置了四肢钢管组合柱 ,从而有效地减小了屋盖的跨度与高度 ,使屋盖的用钢量大大减小。为了适应大跨度屋面温度变形的要求 ,采用了滑板式聚四氟乙烯橡胶支座
The spatial trusses using hollow section steel are introduced at the roof structures of small hall,eastern hall,and west hall in Ningbo International Conference & Exhibition Center.The trapezoid and triangle cross sections are used for the main trusses and sub trusses respectively,and the members of circular HSS are welded together directly at connections.Built up columns that consist of four steel pipes,batten beams and diagonal cable bracings are arranged at the interior of the exhibition halls to reduce span of the roof structures so that it can have much lower material cost compared to without interior columns.To satisfy thermal deformation of the large span roof,the bearings that consist of rubber bonded to metal pads and teflon sliders are applied properly.
