摘　　要：武钢焦化公司2号筛焦楼在振动筛运行期间振动过大,经分析发现该结构异常的竖向振动是由振动筛激振力所引起,且振动筛所在区域的梁板刚度明显不足,为此对振动筛所在区域的梁板构件进行加固,以提高结构构件刚度,控制振动。加固实施完成后,整个楼面无明显振动感觉,达到了预期的减振效果。No.2coke screening building vibrated excessively during the running of vibrating screen in Wuhan Pingmei WISCO United Coking Corp Ltd.It analyzed that abnormal vertical vibration of the structure was caused by the excitation force of vibrating screen,and rigidity of the beam-slab was not enough in vibrating screen area.Therefore the beam-slab has been reinforced to improve the stiffness of components,then control the vibration.No obvious vibration appeared after the strengthening,the floors reached the expected effect of vibration reduction.
