【摘要】 利用ADINA有限元软件研究了考虑液固耦合的立式圆筒形锚固储液罐非线性地震反应。通过分析计算1000m3储液罐自振特性,储液罐的加速度峰值沿罐壁高度变化趋势,罐壁的应力分布等反应,初步揭示其破坏机理,分析结果为储液罐的抗震设计提供重要的参考依据。更多还原

【Abstract】 Using the finite element software of ADINA,nonlinear seismic response analysis of an anchored cylindrical liquid storage tank was performed taking into account the liquid-solid coupling effects.The dynamic vibration characteristics,the peak acceleration response tendency along the height of tank,and the stress distribution of the tank wall corresponding to a tank with a volume of 1000m3 were investigated in order to reveal its failure mechanism.Proposals and recommendations were presented for the seismic design of liquid storage tanks.更多还原
