The Selection and Design of Steel Roof Structure for a Speed Skating Rink on a Certain Avenue

某大道速滑馆钢屋盖结构采用空间管桁架结构,建筑与结构融合为一。文章介绍了风荷载大的沿海地区的大跨度钢屋盖的结构选型,将张弦桁架与普通桁架进行对比分析,阐述了钢屋盖及屋面造型的结构设计。通过针对性的分析及措施阐述,钢屋盖结构刚度及构件应力比均满足规范要求,实现了建筑与结构的有机结合。

The steel roof structure of the speed skating rink on a certain avenue adopts a spatial pipe truss structure,achieving seamless integration of the building and structure.This paper introduces the structural selection for large-span steel roofs in coastal areas with high wind loads,conducts a comparative analysis on truss string and ordinary trusses,and elaborates the structural design of steel roofs and roof shapes.Through targeted analysis and specific measures,the stiffness and component stress ratios of the steel roof structure comply with the code requirements,achieving an organic combination of the building and structure.
