【摘要】 从理论上分析了干摩擦板—弹簧调谐质量系统减震性能,根据拉格朗日方程推导了结构设置减震系统地震动力反应分析计算公式。分析与计算结果表明:设置质量调谐系统之后,结构动力反应层间位移有所减小。当接触面滑动摩擦系数为0.05左右、弹簧系数为25000kN/m、阻尼系数为3000 kN/m.s调谐附加质量为楼层质量的1.0～1.4倍以上时,质量调谐系统具有较好的减震效果、消能效果与复位能力。更多还原

【Abstract】 A theoretical analyzing approach about vibration mitigation system,dry friction plate-spring system,was presented.According to the Lagrange Equation,we can reach the analytical dynamics equation of vibration mitigation system applied in structure.Computation results show that the maximum inter-storey drift was significantly reduced with the tuned mass damper system.The system will exhibit optimum efficiency for vibration mitigation,energy dissipation and restoration with the slip friction factor being 0.05,the spring coefficient 25000 kN/m,the damping coefficient 3000 kN/m.s and the tuned mass 1.0~1.4 times of the storey mass.更多还原
