摘要
某体育场钢结构屋架为倒三角桁架双层曲面空间网格结构,采用临时支撑、单元起吊、空间组拼的方法进行施工,施工时的临时支撑布置和施工完成后对钢结构的卸载及支撑拆除成为施工过程中的关键环节。通过计算机模拟,对不同临时支撑布置、加固及拆除方案进行比较分析,最后确定合理的临时支撑施工方案。
The steel structure roof truss of a stadium is an inverted triangular truss double-deck space grid structure, which is constructed by means of temporary support, unit lifting and space assembling. Through simulation, different temporary support arrangements, reinforcement and demolition schemes are compared and analyzed, and finally a reasonable temporary support construction scheme is determined.
