Abstract
This paper deals with the seismic response simulation model, which is coupled with the physical spring mass subsystem and the modal spring mass subsystem. The effect of participation factor is introduced in mass matrix and the unilateral contact model for slip and stick sue to the friction force is introduced in the equation of motion. The slip response with shaking table excitation test verified the simulation model presented here. Parametric studies for four kind of actual size tank are conducted to examine the effect of participation factor and the friction force on the seismic response of the tank.
