摘要
耗能减震技术通过在结构物的某些部位设置耗能装置,利用其局部变形提供附加阻尼,以消耗地震能量,减小主体结构地震反应,从而达到减震、控震的目的。北京汽车产业研发基地项目建筑造型较特殊,结构的扭转效应比较大,为了减小结构的地震响应,尤其是在罕遇地震下的响应,在关键部位布置了若干黏滞流体阻尼器。采用MIDAS软件对采用阻尼器后的耗能结构与初始结构进行计算比较。结果显示,黏滞流体阻尼器的采用有效控制了结构在地震作用下的响应。
The aim of reducing and controlling the earthquake response of the main structure can be realized by the energy dissipation technology which can be implemented by the additional damping of energy dissipation devices.The architectural modeling of Beijing Auto RD Center is special and the torsion effect of the structure is large.Then the viscous fluid dampers are fixed on the key regions in order to reduce the earthquake response especially the strong earthquake response of the structure.The analysis result obtained by MIDAS proves the good vibration resistance effect of viscous fluid damper.
