本文基于ＴｕｎｅｄＭａｓｓＤａｍＰｅｒ（简称ＴＭＤ）的原理，通过振动台模型试验，进行了悬浮顶层减震结构系统的研究。这种结构由主结构与悬浮顶层组成，采用叠层橡胶支座作为二者之间的连接装置，它与顶层楼体共同形成一个大型的ＴＭＤ系统。试验表明：这种新型的减震结构系统在不同地震波的作用下，主结构顶层的加速度响应减少了１／４以上。由于这种结构系统施工工艺相对简捷，因此具有良好的经济性与实用价值，值得在工程上应用与推广。
Based on the principle of TunedMassDamPer (abbreviated as TMD), this paper studies the suspension top-layer damping structure system through shaking table model test. This structure consists of a main structure and a suspended top layer. A laminated rubber support is used as a connecting device between the two. Together with the top floor, it forms a large TMD system. Tests have shown that this new type of shock absorbing structure system reduces the acceleration response of the top layer of the main structure by more than 1/4 under the effect of different seismic waves. Because this type of structural system has a relatively simple construction process, it has good economic and practical value and is worthy of being applied and promoted in engineering.
