本文研究了储罐结构的地震反应模拟，该模型由物理弹簧质量子系统和振型弹簧质量子系统组成。在质量矩阵中引入了参与因子的影响，在运动方程中引入了摩擦力引起的滑移和粘滞的单向接触模型。利用振动台激振试验进行了滑移响应试验，验证了仿真模型的正确性。对四种实际尺寸的储罐进行了参数研究，考察了参与系数和摩擦力对储罐地震反应的影响。
This paper deals with the seismic response simulation of storage tanks, 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 due 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.
