Abstract
Abstract The seismic characteristics of liquid sloshing in partially filled sloped bottom tank are investigated numerically. Six different ground motions classified on the basis of low, intermediate and high frequency contents are selected to determine the dynamic characteristics of liquid in sloped bottom tanks. The effect of different slope angle on the frequency contents of earthquakes are investigated. The liquid domain is discretized as the combination of three node triangular and four node quadrilateral finite elements. The individual contribution of impulsive and convective response components of hydrodynamic behavior in terms of base shear force and hydrodynamic pressure distribution along the walls of the containers are successfully measured. The efficacy of the developed numerical model is validated with the existing published results.
