Research of the Control of the Vibration Caused by Human in Long-Span Terminal Aerobridge

In order to control the degree of comfort in vibration caused by human in a steel aerobridge of Shenzhen T3 terminal building, the theory of structural vibration control and TMD (Tuned Mass Damper) was used to control the vibration caused by human and conduct comfort design. At first, 3D analysis model of the structure was developed through general finite element analysis software MIDAS / GEN. And time-history analysis was carried out in different working conditions of human walking or jumping to analyze the dynamic response before and after the TMD was installed. Then, vibration test was conducted in-situ to determine its dynamic property and record its peak acceleration before and after the TMD were installed. Test data was then compared with data from the analysis model of the structure based on analysis software. The results show that the installing of TMD and making adjustment of the stiffness of the TMD based on the actual test make the structure meet requirements of degree of comfort in vibration caused by human. The effect of the vibration control is good.
