摘要
某钢筋混凝土框架结构厂房将两台选粉机置于楼面 ,选粉机的水平旋转引起结构沿纵向发生过大的水平振动。现场测试了房屋的动力性能及各层楼面的水平位移 ,进行了结构动力计算 ,分析了结构振动的原因 ,并对振动危害程度作出了评价 ,提出了降低振动影响的措施。
Horizontal vibration was caused significantly along the longitudinal direction of a reinforced concrete frame by two rotatory equiments.The dynamic parameters of the structure are measured,and the dynamic evaluation of the frame is made.Through the vibratory analysis of the frame,the degree of the harm of vibration is assessed,and the measures are presented to reduce the influence of the vibration.
