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。
Energy-saving damping technology through the provision of energy-consuming devices in some parts of the structure, the use of local deformation to provide additional damping to dissipate seismic energy to reduce the seismic response of the main structure, so as to achieve the purpose of shock absorption, shock control. Beijing Automotive Industry R & D base construction project more special shape, the structure of the twisting effect is relatively large, in order to reduce the seismic response of the structure, especially in rare earthquake response, the layout of a number of key viscous fluid damper. The MIDAS software is used to calculate and compare the energy dissipation structure and the initial structure after using the damper. The results show that the adoption of viscous fluid damper effectively controls the response of the structure under earthquake action.
