摘要
镇江大港体育馆钢屋盖采用变高度管桁架结构体系,其屋盖和墙面组成一个整体,在充分考虑建筑空间要求与结构传力特点的基础上,优化布置次桁架和支撑体系,加强了管桁架结构体系的空间受力性能。通过灵活布置铰支座、X向弹簧支座、Y向弹簧支座和双向弹簧支座四种形式的支座,保证钢结构整体刚度和受力性能处于最优状态。
The steel structure of Zhenjiang Dagang gymnasium adopts various-height tubular truss structure, where roof and wall are integrated into a whole system. Secondary truss and supporting system are optimized with sufficient consideration of building space and structural force transfer characteristics, to successfully improve the spatial force bearing capacity of tubular truss structure system. Four types of support, including hinged support, X-shape spring support, Y-shape spring support and bi-directional spring support, are set on to ensure the optimal rigidity and bearing capacity of the whole steel structure.
