【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】 Aiming at the unanchored storage tanks,considering the interaction between foundation and tank structure,and the coupling of liquid-tank wall,the numerical analysis of the three-dimensional seismic response is made with the help of the finite element method.The results show that the acceleration,lifting,axial stresses,the base shear force and the base bending moment of the tank under three-dimensional seismic rground motion is greater than that under one-dimensional horizontal seismic ground motion.更多还原
