【摘要】 本文采用大型有限元程序ANSYS对立式储液罐的地震反应进行了非线性数值分析,考虑了罐体和内部液体的相互作用,得到了3个不同容积的储罐,在不同峰值的地震动时程输入下的反应结果。结合地震灾害中立式储罐的地震破坏现象和特点,以及现有的立式储罐地震破坏预测方法,提出了立式储罐的地震破坏快速评估方法。更多还原

【Abstract】 In this paper,the earthquake responses of cylindrical liquid storage tanks are analyzed by using the computer program ANSYS and considering the interaction between tanks and the liquid in the tanks.The numerical results of three tanks with different volumes are obtained,assuming the earthquake inputs to be real earthquake time history with different peak values.The suggested fast assessment method is given on the basis of the numerical results of the seismic damage to the cylindrical liquid storage tanks and the existing seismic damage predication methods.更多还原
