【摘要】 水塔设备在地震作用下具有严重的安全隐患,必须进行抗震设计。采用有限元分析软件AN-SYS建立不同支承高度和不同水箱储水量水塔的空间分析模型,分别采用反应谱法和时程分析法对比研究了水塔在水平地震作用下的弹性地震反应,研究支承高度和水箱储水量对水塔自身动力特性和动力响应的影响,并对比反应谱和动力时程法的计算结果,提出了对钢筋混凝土抗震设计的具体建议,以供实际工程参考。更多还原

【Abstract】 The seismic load on the water tower equipment usually results in a significant safety hazard,so seismic design of water tower should be carried out.The time history analysis and response spectrum analysis of seismic response of water tower subjected to horizontal seismic wave are performed with ANSYS software,based on the numerical study,the dynamic response characteristics of the reinforce concrete tower in the case of different height and different water reservation are discussed and the two type analysis results are compared,the research work can provide a reference for the seismic design of RC structures.更多还原
