Vibration and earthquake double-control design method giving priority to vertical industrial vibration isolation
The invention provides a vibration and earthquake double-control design method giving priority to vertical industrial vibration isolation. The vibration and earthquake double-control design method giving priority to vertical industrial vibration isolation comprises the following steps of (1) arranging a vertical industrial vibration isolation device, wherein a spring vibration isolator is mounted (1) in the vertical direction of a building needing vibration isolation so as to achieve a vibration isolation effect; and (2) arranging a horizontal earthquake isolation device, wherein a viscous damper (2) is installed in the horizontal direction of the building needing earthquake isolation based on an original earthquake resistance. The steel spring vibration isolator, the viscous damper and the energy consumption design of the structure form a same-layer combined shock isolation system, firstly, the steel spring vibration isolator is used for carrying out integral and systematic modal optimization design and vibration isolation effect control, earthquake fortification checking calculation is carried out on the basis, and when deformation of the vibration isolator exceeds the limit, the viscous damper is configured for limiting and energy consumption, vibration and earthquake harm elimination is jointly achieved, vibration and earthquake double-control is met at the same time, the industrial vibration requirement is met, horizontal deformation of an earthquake isolation layer can be resisted, and safety, comfort and economical efficiency are all guaranteed.
本发明提供了以竖向隔工业振动为主的振震双控设计方法，包括：(1)设置竖向隔工业振动的装置，包括：沿需要隔振的建筑竖直方向安装弹簧隔振器(1)以达到隔振效果；(2)设置竖向隔工业振动的装置，包括：沿需要隔震的建筑水平方向在原有建筑的抗震基础上安装粘滞阻尼器(2)；钢制弹簧隔振器和粘滞阻尼器以及结构自身的耗能设计形成一个同层组合隔震系统，首先利用钢弹簧隔振器进行整体的系统的模态优化设计和隔振效果控制，在此基础上进行地震设防验算，当隔振器变形超限时，配置粘滞阻尼器限位和耗能，共同达到振动和地震危害的消除，同时满足振震双控，既满足工业振动要求，又能抵御隔震层的水平变形，安全性、舒适性和经济性都得到了保证。
