冷却塔模态分析、风荷载和地震荷载作用分析及成型冷却塔的稳定性分析,国内外研究比较多,而施工过程中冷却塔的整体稳定性分析尚没相关资料.利用欧洲规范关于混凝土性能和龄期的成果,借助有限元软件STAAD,对某冷却塔施工过程整体稳定进行分析,结果表明随施工高度增加,整体稳定性降低.将有限元计算的稳定系数和规范值比较,说明差异原因,表明结果是可用的,可为类似工程提供参考.
Cooling tower modal analysis, wind load and seismic load analysis and analysis of the stability of the cooling tower, more and more studies at home and abroad, and the overall stability analysis of the cooling tower in the construction process is not yet relevant information.Using the European norms on concrete performance And the result of the age, the finite element software STAAD was used to analyze the overall stability of a cooling tower construction process. The results show that the overall stability decreases with the increase of the construction height. The stability factor of the finite element calculation is compared with the standard value to show the reason of the difference , Indicating that the results are available, can provide a reference for similar projects.
