摘要
采用有限元软件ETABS建立了某高层建筑的整体有限元模型,模拟其在实测风荷载作用下和单台动力设备作用下楼板的振动响应,并与现场振动测试结果进行了比较,从而掌握了楼板在环境激励和设备激励作用下的振动规律,为拟建高层建筑内精密仪器的微振动控制提供了分析数据和计算依据。
The integrated finite element model of a high-rise building is established with respect to FEM software ETABS in this paper so as to simulate the vibration responses of the slab subjected to the field measurement wind load and single facility dynamic action.The calculation results are compared with on-the-spot measurement data in order to know the vibration rule of the slab under environmental and facility stimulations,on the basis of which the analytical data and theoretic foundations are obtained to control the micro-vibration of the precise instruments in the high-rise building.
