Seismic Large Amplitude Liquid Sloshing—Theoryby Medhat A. Haroun, Univ of California, United States,

Abstract: The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing on the tank's response under arbitrary horizontal excitations is proposed. The nonlinearity of both the kinematic and the dynamic conditions is considered. Because the location of the free surface is unknown, a numerical scheme is developed to transform a two-dimensional uniform rectangular grid into a boundary conforming curvilinear grid with prescribed arbitrary boundaries. A set of governing nonlinear equations is obtained and solved in the uniform rectangular mesh by employing a finite difference scheme.
