北京某体育馆结构方案设计与分析

Design and analysis of a gymnasium structural scheme in Beijing

北京某体育馆外形近似长方体,采用柱顶斜拉索立体钢桁架结构。介绍了结构方案设计的全过程,同时对缆索预应力的确定、结构内力和变形以及钢结构的地震反应进行了较详细的分析,设计了结构杆件和关键节点,得出的一些结论供相关工程参考。

Cable-stayed steel truss structure is applied to a gymnasium in Beijing which is like cube shape. Analysis was carried out on the key issues, such as cable prestress value, force and deformation calculation, aseismatic analysis, member and joint design, and so on. Finally some useful conclusions were brought forward.
