摩擦板与弹簧协同隔震的性能研究

The performance about the collaboration of friction plate and spring isolation system

从理论上分析了干摩擦板-复位弹簧隔震系统的隔震性能,根据拉格朗日方程推导了结构无隔震系统、地下室顶板与基础顶面分别设置隔震系统地震动力反应分析计算公式。分析与计算结果表明:结构设置减震系统后楼层位移、层间位移、速度及加速度明显减小。在基础顶面设置隔震系统比地下室顶板设置隔震系统具有较好的隔震效果。

From the theoretical analysis of dry friction plate-Reset isolation performance spring isolation system, ac- cording to the Lagrange equations derived structure without isolation system, the top surface of the basement roof and foundation were set response analysis of seismic isolation system calculated power. Analysis and calculation re- sults show that ： the structure sets up among floors displacement layer damping system after the consequences of dis- placement, velocity and acceleration significantly reduced. Setting isolation system set up on the basis of the top surface than the basement roof isolation system has good isolation effect.
