Abstract

Intent of the work is to evaluate the behaviour of liquid fuels contained in storage tanks, when subject to an earthquake. Particular attention has been addressed to fluid motion, defined sloshing, and to the forces which it exercises on tank structure. The analysis was performed with the help of a CFD commercial software, properly integrated with appropriate subroutines. The tank analysed is cylindrical (diameter = 10 m, height = 11m). The simulations were made for different filling levels, 25, 50 and 75%, subjecting the tank to 7 different acceleration inputs. Results are presented in form of temporal variation of pressure, movement of fluid gravity centre, forces and moments on the structure.
