摘要
采用SAP2000结构分析软件对安顺体育中心体育场大跨度悬挑结构进行模拟和分析,得到不同的卸载方案对卸载过程和卸载完毕后屋盖杆件及屋盖施工的影响结果.对比卸载过程中和卸载完毕后最大卸载位移量、最大反力及卸载完毕状态与设计状态应力比,分析较为合理的卸载方案.
Abstract
The large-span cantilever structure of Anshun Sports Center Stadium in Anshun is simulated and analyzed by SAP2000 structure analysis software. The influence of different unloading schemes on the roof bars and construction which is in the unloading process and after unloading completion is obtained. The reasonable scheme of unloading sequence which is got through comparing the maximum unloading displacement, maximum counter-force in the unloading process and after unloading completion and the stress ratio between the unloaded state and the design state.
