【摘要】 针对立式储罐,考虑液固耦合效应、地基与储罐结构的相互作用,采用有限元分析方法,对储罐在三维地震荷载作用下动反应进行了数值分析。分析结果表明：储罐三维地震加速度反应较一维地震加速度反应增加、提离高度明显放大、储罐轴向应力增加、基底剪力与弯矩增大。更多还原

【Abstract】 Aimed at the unanchored storage tanks,considering the interaction of foundation and tank structure, And the coupling of liquid-tank wail,the numerical value analysis of the three-dimensional seismic response is processed with the help of the finite element method.The results are indicated that the acceleration,lifting,axis stresses,the base shear force and the base moment responses of the tank under three-dimension seismic is greater than that of the tank under one-dimension horizontal seismic.更多还原
