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.
