对TMD控制结构竖向地震做了理论分析,以主结构位移方差为优化目标函数得到了TMD最优系统参数计算公式并进行了分析,由算例分析知道此参数是有效的,为TMD控制竖向地震作用下的结构振动提供了理论依据。
TMD used in controlling the vibration of structural in the vertical earthquake action is analyzed. According to the optimal object of minimum of the main structural displacement variance, it is derived TMD system computation formula of the optimal parameter. The calculating results show that the formula are effective .These provide theoretical basis for TMD used in controlling the structural vibration in the vertical earthquake action.
