湛江港某钢结构转运站（TH10）振动分析

港口转运站投入使用后出现振动的现象比较多。采用现场测试和有限元分析两种方法,分析湛江港某钢结构转换站（TH10)产生振动的原因并采取相应的措施,使振动情况得到很大的改善,符合人体的舒适度范围。为以后类似问题提出解决思路和建议：针对跨度较大的楼面,设计时应考虑增加跨中部位的水平和竖直刚度,避免振动时发生较大变形;在楼层机械设备位置,应增加结构抗干扰能力,保证外部能量在结构内部有效传递。

Vibration analysis of a steel structure transfer station in Zhanjiang Port

There are many vibration problems after the port transfer station is put into use.By means of on-site test and finite element analysis,the causes of vibration in a steel structure transfer station(TH10)in Zhanjiang Port are analyzed,and corresponding measures are taken to improve the vibration situation and meet the comfort range of human body.In order to solve similar problems in the future,some ideas and suggestions are put forward:in view of the large span floor,the horizontal and vertical stiffness in the middle part of the span should be considered in the design to avoid large deformation when vibration occurs;the anti-jamming ability of the structure should be increased to ensure the effective transmission of external energy within the structure at the location of the floor machinery and equipment.
