中文摘要：

为了减小双向偏心结构的地震响应,采用悬吊质量板对此结构进行振动控制。讨论了结构在有无悬吊质量板情况下的自振特性。通过数值计算,证明了悬吊质量板对结构平动和扭转震动都有控制作用,当悬吊质量板震动频率接近结构震动基频时,对于结构平动和扭转震动的减震效果最大可分别达到37.2%和54.4%。基于悬吊质量板简单、经济、易于实施等优点,可将其作为偏心结构扭转震动的有效控制措施。

英文摘要：

In order to reduce the seismic response of the two-way eccentric structure,suspension-mass slabs were used to control the vibration of the structure. The natural vibration characteristics of the structure were discussed in the presence of suspension-mass slabs situation. Through numerical calculation,it is proved that suspension-mass slab has positive control effect on the translational motion and torsional vibration of structure. When the vibration frequency of suspension-mass slabs is close to the fundamental frequency of structure,the vibration damping effect for the translational motion and torsional vibration of structure can reach 37.2% and 54.4%,respectively. Based on such advantages of the suspension-mass slabs as simpleness,economy and easiness to implement,it can be used as a effective control measure for torsional vibration of eccentric structures.
