脉动风载作用下巨-子型控制结构体系中耗能阻尼器的应用

The application of the dissipating energy dampers in the mega - sub controlled building system under random wind loads

基于随机振动复模态分析理论,计算提出了巨-子型控制结构体系在随机风载作用下,结构反应与附加粘滞阻尼器阻尼值的关系;利用搜索的方法,寻找出最优的附加阻尼值;研究分析的结果表明,新型的巨-子型控制结构体系在合理安装附加粘滞阻尼器后,减振效果非常理想。

The complex model theory of random vibration is applied to solve the value of displacement and acceleration of the structure. Under the action of random wind loads, the relation between the response of mega - sub controlled structure and the damping value of the attaching viscous dampers is advanced. The best damping value of the attaching dampers is found with the method of constantly searching. The excellent effect of vibration - absorption is demonstrated, when the viscous dampers is fixed in the building system in reason.
