【摘要】 依据拉格朗日方程推导了巨型框架采用干摩擦板-弹簧隔震系统的动力反应分析计算公式,并根据龙格-库塔法利用MTALAB语言编制程序求解。结果表明,采用干摩擦板-弹簧系统能使动力反应层间位移减小。当层间刚度系数取160 000kN/m、滑动摩擦系数取0.01时,隔震效果可达60%~84%左右,减震效果达到最佳。更多还原

【Abstract】 A theoretical analyzing approach about vibration mitigation system,dry friction plate-spring system,was presented.It starts from Lagrange Equation in analytical dynamics.The solution was presented with Longe-Kuta method and was programmed with MTALAB software.The results show that the dry friction plate-spring system can reduce the seismic dynamic response of inter-story drift.It is also shown that when the Stiffness coefficient between the layers is about 160000kN/m and the slipping friction coefficient is about 0.01,the seismic isolation effectiveness could be about 60% ~84% to achieve the best damping effect.更多还原
