Abstract

The characteristics of the wind-induced vibration of a super high-rise building were studied through field measurement and numerical simulation in this paper.The structural vibration response was measured using structural vibration monitoring systems mounted on the top of the building.The acceleration

displacement amplitude and dynamic characteristics of the structure were analyzed under normal wind and No.12typhoon in 2008.Based on the measured dynamic characteristics

the equivalent aero-elastic model of the super high-rise building was established.Program ANSYS was used and combined with CFX to simulate the vibration of fluidstructure interaction（FSI）between the wind field and the building.The inlet boundary condition of the mean wind profile was adopted.The time histories of displacement and aerodynamic force coefficient

spectrum analysis and vortex shedding mode at different height and different wind speed on the top of the building are obtained.The top lateral displacement of the building was compared with present and other field measurement results.It is shown that the numerical method adopted to simulate the FSI is feasible and it also can provide necessary technical basis for wind-resistant design and comfort calculations of actual super high-rise building.
