共享调谐质量阻尼器(STMD)在附属结构减震中的应用

SHARED MASS DAMPER (STMD) USED TO REDUCE THE SEISMIC RESPONSE OF SECONDARY SYSTEMS

  • 摘要: 鉴于在两个频率接近的临近附属结构之间设置连接粘滞阻尼器(Viscous Damper, VD)的减震效果往往很差,该文采用了一种新型的减震方法:共享调谐质量阻尼器(Shared Tuned Mass Damper, STMD)的方法。该方法在临近的附属结构之间附加公共质量块,并以粘滞阻尼器连接,利用附属结构与质量块之间的相对运动来耗能减震;同时实现了两个附属结构的协调振动,避免地震作用下附属结构碰撞的发生,并且当附属结构频率接近时共享调谐质量阻尼器(STMD)有很好的减震效果。该文研究了在临近附属结构之间分别采用粘滞阻尼器(VD)和共享调谐质量阻尼器(STMD)时的减震效果,并对共享调谐质量阻尼器(STMD)减震效果的适用情况和影响因素进行了分析。

     

    Abstract: By considering that the strategy of Viscous Damper (VD) does not behave well in reducing the seismic response of secondary systems, a new strategy termed as Shared Mass Damper (STMD) is introduced in the paper. In the strategy, a shared mass connected by viscous dampers is placed between two adjacent secondary systems, dissipating earthquake energy by the relative displacement between the secondary systems and the shared mass. Meanwhile, two adjacent secondary systems are made to vibrate coordinately so as to avoid the pounding. The new strategy of Shared Mass Damper (STMD) can work well, especially when the frequencies of two secondary systems are close to each other. The effects of two strategies as well as the influencing factors of STMD and VD on reducing the seismic response of secondary systems are studied.
