Abstract:
The wind-induced vibration comfort level of a wind-sensitive high-rise building was analyzed. The wind-induced aerodynamic stresses on the building were evaluated using the large eddy simulation(LES)technique. The narrowband synthesis random flow generation(NSRFG)method was used as the inflow turbulence generator for LES. Then, the extreme value of the acceleration on the top of the building is selected as the occupant comfort index of the wind-induced vibration, which was calculated using the story shearing equivalent model and compared with reference values obtained by structural design software SAP2000. The results show that the wind factors present an increasing trend as the height increases. The LES can effectively capture details. The predicted peak values of the wind-induced responses are less than those produced by SAP2000, showing that the comfort analysis of wind-induced vibration is conservative using the present structural design software.
