以某工程为背景,以通用有限元结构分析与设计软件Midas-gen为计算工具,建立高位水塔的仿真模型并进行了分析和研究。研究结果表明:1屈曲分析得到的临界荷载同理论计算值有一定差别,主要原因在于初始缺陷的存在;2加劲肋可有效提高筒壁式水塔整体屈曲的临界荷载;3三立柱支架式水塔的受力性能满足使用及抗震要求,且造型美观;4水塔中的水有减震作用;5通过设置改善地震中水塔中心分布的装置可以减轻重力的P-Δ效应。
Taking a project as the background, the finite element analysis and design software Midas-gen is used as the calculation tool to establish the simulation model of the high water tower and analyze and research it. The results show that: 1, the critical load obtained by buckling analysis has some differences with the calculated values, mainly due to the existence of initial defects; 2 stiffeners can effectively improve the overall buckling load of the cylindrical wall water tower; Its performance meets the requirements of use and seismic resistance, and its appearance is beautiful. 4 The water in the water tower has a damping effect. 5 The P-Δ effect of gravity can be reduced by setting the device to improve the center distribution of the water tower in the earthquake.
