摘要
根据拉格朗日方程推导了结构设置FPS调谐质量系统地震动力反应分析计算公式,并考虑了接触面滞滑效应的影响。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0.15左右、滑道半径为0.7 m、调谐附加质量为楼层质量的1.4倍以上时,质量调谐系统具有较好的减振效果、消能效果与复位能力。
A theoretical analyzing approach about a novel FPS tuned mass damper system applied in structure for vibration mitigation is derived. It starts from Lagrange Equation in analytical dynamics. The stick effect had been taken into consideration in the analyzing process. Computation results show that the maximum inter-storey drift was significantly reduced with FiX3 TMD system. The system will exhibit optimum efficiency for vibration mitigation ,energy dissipation and restoration with the slip friction factor being 0. 15 ,the slide radius 0. 7 m and the tuned mass 1.4 times of the storey mass.
