摘要
本文针对上海虹桥商贸城M区多层框架结构 ,在屋顶 2 8台冷却塔风机转动形成的动力荷载作用下 ,是否产生共振现象进行了计算分析 ,并对减小振幅避免共振提出了相应的建议。
Based on the analysis of a multi-story frame in M zone of Shanghai Biz-Trade City,this paper illustrated the possibility of resonance of the frame under the dynamic load,which was created by 28 cooling tower fans in the garret of the frame. Also the suggestion to reduce the amplitude of the vibration and to avoid the resonance was put forward.
