干摩擦板—复位弹簧隔震系统特性的研究
|
摘要
从理论上分析了干摩擦板—复位弹簧隔震系统的一些特性,并计算了两个不同层数的建筑物在地震作用下的动力反应。计算结果表明,在通过优化选取合理参数的条件下,应用摩擦板—复位弹簧系统隔震具有明显的减震效果,最大位移值与层间位移值大幅度减少。底层层间位移可以减少80%以上,顶层层间位移可以减少60%左右。为保证系统的正常复位,复位弹簧的刚度系数应大于其下限值。在设有隔震系统的情况下,竖向地震的影响对计算结果影响很小以至于可以忽略。
Some behavior properties of dry friction component-reposition string vibration isolating system is analyzed.The seismic dynamic response on two buildings with the vibration isolating system have been evaluated and the results show that this kind of seismic isolating system is apparently effective if the reasonable parameters could be obtained by optimization.The maximum inter-storey drift could be obtained by optimization.The maximum inter-storey drift could be drastically decreased by about 80% at base storey or about 60% at top storey.The elastic coefficient of the reposition string should be larger than the lower limit in order for the effective reposition ability of the system.On the other hand,the influence of the vertical seismic action to the horizontal dynamic response is so small that it could be neglected.
