【摘要】 用于不规则建筑扭转振动控制AMTMD最优参数准则定义为:设置AMTMD不规则建筑的最大扭转角位移动力放大系数最小值的最小化。AMTMD有效性准则定义为:设置AMTMD不规则建筑最大扭转角位移动力放大系数最小值的最小化与未设置AMTMD不规则建筑最大扭转角位移动力放大系数之比。使用定义的准则,研究了不规则建筑NER和TTFR对AMTMD控制不规则建筑扭转角位移的最优参数和有效性的影响。更多还原

【Abstract】 The criterion for searching the optimum parameters of AMTMD for torsional vibration control is defined as the minimization of minimum values of maximum torsional displacement dynamic magnification factors of an asymmetric building with AMTMD. The criterion for measuring the effectiveness of AMTMD is defined as the ratio of the minimization of minimum values of maximum torsional displacement dynamic magnification factors of asymmetric building with AMTMD to that without AMTMD. Making use of these two criteria, the influences of NER and TTFR of asymmetric building are investigated on the optimum parameters and effectiveness of AMTMD in reducing torsional vibration.更多还原
