Analysis of Wind-Induced Vibration Response for a Long-Span Double-Arch-Support Steel Structure

Abstract:

As a new long-span double-arch-support steel structure system is applied to a stadium, it is necessary to study the wind-induced vibration response of the roof structure to meet the need of design. The modal analysis and the response analyses which include static wind response and wind-induced vibration response are calculated by ANSYS. The results show that the natural vibration frequency of structure is intensive (0.93 Hz~4.2 Hz). The most unfavorable wind direction angle of 135^o is selected to study the wind-induced vibration response. And the wind-induced vibration coefficient calculated is satisfactory when compared with the wind tunnel test. It can be seen that it is feasible to use the stochastic simulation analysis method of wind-induced vibration response to get the wind-induced vibration coefficient.
