Abstract:
Based on the wind tunnel tests on the aero elastic model of a long-span arch bridge, this paper researched the effect of structure under transversal wind loads on different skew angles. The dynamic characteristics and static rigidity of model were tested, and the structure was tested under transversal wind loads on different skew angles. The analysis shows that the bridge will come to the role of the most adverse condition when the wind direction is cross-bridge. And the corresponding key position in the bridge enlarged with the increased angle of skew wind. Furthermore, the skew wind load cannot be decomposed by trigonometric function and superposed to obtain the structure wind load effect, because the actual effect will be more negative. 2 tabs, 10 figs, 13 refs.
