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。
In view of the fact that the damping effect of viscous dampers (VDs) installed between two adjoining adjacent structures at near frequencies is often poor, a new damping method is proposed in this paper: a tuned mass damper Shared Tuned Mass Damper, STMD). In this method, a mass of public mass is attached between adjacent subsidiary structures and connected by a viscous damper, and the relative motion between the subsidiary structure and the mass is used to dissipate energy and reduce vibration. At the same time, the coordinated vibration of the two subsidiary structures is realized, Avoidance of the collision of satellite structures caused by earthquakes and good damping effect of shared tuned mass damper (STMD) when the frequencies of satellite structures are close to each other. In this paper, the damping effect of viscous damper (VD) and shared tuned mass damper (STMD) between adjacent structures is studied and the application of shock absorption effect of shared tuned mass damper (STMD) And influencing factors were analyzed.
