摘要
佛山高明体育馆大跨度钢结构与混凝土结构完全脱开,正立面由7个并列的拱形门式刚架组成,相邻拱形斜柱相交形成并列M形结构。大跨度钢结构屋盖由并列圆柱壳组成,在相邻圆柱壳相交的部分设置三角形空间桁架。并在侧立面斜柱间设置预应力拉杆支撑。该工程结构形式新颖,受力合理,经济性较好。本文介绍了高明体育馆结构体系的布置特点、荷载取值、稳定性分析及焊接节点的设计等,可为类似工程提供参考。
The large span steel structure of Foshan Gaoming Gymnasium,which is separated with concrete structure,is composed of seven parallel arched portal frames. Adjacent arched columns intersect with each other and form an M-shaped structure. Also,the roof is consisting of seven cylindrical shells,with triangular truss installed between every two adjacent shells. In side elevation,prestressed tension rods are used between the inclined columns. In this project,architectural effects and structural performance are consistent with each other and bring forth integrated harmony. This article describes the arrangement of the structural system,load value,stability analysis as well as design process for welded joints,which provides a reference for other similar projects.
