The elephant foot bulging deformation of rigid walls of liquid-storage tanks under horizontal and vertical seismic ground motions is analyzed by using the finite element model involving fluid sloshing and tank bottom uplift with ANSYS.

• 摘要基于ANSYS软件建立了考虑液体晃动和罐底提离立式储液罐有限元模型，分别进行了水平地震和竖向地震作用下罐壁“象足”变形分析。
