铅芯橡胶支座调谐质量系统减震效果
|
摘要
根据拉格朗日方程推求了结构设置LRB调谐质量系统的动力反应计算公式,并编制了求解软件。分析与计算结果表明:设置调谐质量系统之后,结构动力反应层间位移有所减小。当LRB刚度为30×103、阻尼系数为3000、调谐附加质量为楼层质量的1.0倍以上时,调谐质量系统具有较好的减震效果、消能效果与复位能力。
A theoretical analyzing approach about a novel LRB 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 LRB TMD system.The system will exhibit optimum efficiency for vibration mitigation,the stiffness 30×103,the damping 3000and the tuned mass 1.4 times of the storey mass.
