摘要
由于钢结构质轻、高强、可塑和易连接的性质,使其成为大跨度结构的首选形式。2008年北京奥运会五大场馆的屋面均采用了钢结构。为了消除温度变形和安装允许误差的影响,对大跨度钢结构屋面在支座部位采用了滑动球铰支座。以五棵松篮球体育馆为例,介绍大跨度屋面结构球铰支座的安装方法,希望能对其他类似工程有借鉴意义。
With the development of steel production, all kinds of building with steel structures arise in China. Due to the quality of lightness, high-strength, plasticity and connecting easiness, steel structure becomes indispensable material for large-span structure roofing. The steel structure is used for the roofings of five major gyms and stadia of the 2008 Beijing Olympic Games. The slip spheric joint support is also used for the large-span steel structure roofing in order to dispel distortion by temperature change and the allowed error. This paper takes basketball stadium of Wukesong as an example to introduce the installation of spheric joint support for large-span roofing steel structure, which may provide benefits for other similar projects.
