考虑滤波特性的隔震建筑上部结构选型

Selection of upper-structure form of vibration-proof buildings with consideration of filtering characteristics

提出了采用能量传递关系,通过Matlab程序对上部结构采取不同结构形式的隔震系统的滤波特性进行对比的方法,对上部结构进行了对比设计.分析了不同类型的上部结构对隔震建筑的减震效果、结构的可靠性以及工程造价的影响.该方法可以选择较优的上部结构从而使隔震建筑达到减震效果好且工程造价较低的效果。

Energy transfer relationship was put forward. Through the comparison of filtering in base-isolation buildings with different upper structures by Matlab, the most appropriate upper structure can be designed. The isolated effectiveness, the reliability of structure and the project cost etc. in the different upper structures have been analyzed. The results showed that the selection of structural form is appropriate; the effect of remarkable vibration reduction and the low cost in the isolated building could be realized.
