摘要
2011年世界大学生运动会主体育馆钢屋盖为单层折面网格结构,采用高空定点拼装、累积旋转滑移的安装方案。钢屋盖安装完成后,共有49个临时支承点。通过模拟计算分析,采用分阶段分级同步综合卸载方案实施,取得了较好的效果,可为同类工程的施工提供借鉴。
The steel roof of the main gymnasium for 2011 World University Games is a monolayer-folding grid structure,for which the installation scheme of upper air point assembling and accumulation revolving slip was used.There would be 49 temporary bracing points when finishing the erection of the steel roof.Good effect was got by implementing the scheme of stage and progressive synchronizing integrated unloading,according to the simulative calculation and analysis,which provided experience for construction of similar projects.
