某体育场钢结构飘雨篷设计

DESIGN OF STADIUM STEEL FLOAT AWNING

针对青岛理工大学嘉陵江路新校区体育场西看台钢结构悬挑飘雨篷的设计,研究了悬挑飘雨篷的结构静力计算、动力响应以及节点连接的构造形式。钢结构悬挑飘雨篷的梁柱连接节点采用主梁贯穿钢柱的构造形式,拱梁与主梁节点、拉杆与主梁节点均采用连接钢板的构造形式。利用SAP2000结构设计软件对整体结构进行了静力计算和动力响应分析,计算过程中考虑了各种风荷载工况组合。分析结果表明:悬挑飘雨篷杆件的最大应力比、悬挑最大竖向挠度值均满足相关规范设计要求。

For the design of the stadium steel float awning in Jialingjiang road campus of Qingdao Technological University, the structure static calculation and dynamic response of the cantilevered float awning and structural form of connections are studied . Beam column node of the steel cantilevered float awning adopts the structure style that the main beam runs through the steel column, while arched beam main beam nodes and tension rod-main beam nodes use the style that the members are indirectly connected by steel plate. The static analysis and dynamic characteristic analysis are used by the SAP 2000 software calculations which take fui1 account of the various wind load combinations. The results show that the maximum stress ratio of the cantilevered steel float awning member bars and the maximum vertical deflection at beam end all meet the design requirements of the codes.
