应用粘滞性阻尼器的耗能减震建筑的抗震性能研究

Research on Seismic Performance of Energy Absorption Building that Applying Viscous Damper

本文从耗能减震建筑的特点和动力特性两方面出发,在《建筑抗震设计规范》基础之上,对耗能减震结构在地震作用下的动力特性进行分析研究。在上部结构附设粘滞性阻尼器,在地震时可以大大降低建筑物倾覆的可能性。通过有限元算例的分析,可以看到在地震作用下建筑物的受力状态和变形情况有所明显改善。

Starting from the characteristics of energy absorption building and the dynamic property,on the basis of ＂ Antidetonation Design Specification of Buildings＂,this article analyzes the dynamic characteristics of energy absorption structures under the action of earthquake.Attaching viscous damper in the upper structure can greatly reduce the possibility of overturning the building in the earthquake.Through the analysis of finite element example,we can see that the stress and deformation situation of buildings has improved significantly under the action of earthquake.
