Abstract :
There are many cases where the vortex-induced oscillations estimated by wind tunnel tests are not observed in full-scale bridges. Many researchers suggest that these are caused by turbulence of natural wind. Certainly, it is true that turbulence controls the vortex-induced oscillation. However, the turbulence scale in wind tunnel test is usually too small to estimate its effects on a full-scale bridge in natural wind. In this study, the vortex-induced oscillation of a bridge model in large-scale turbulence flow was examined by using the slowly fluctuating wind generated with an active-controlled wind tunnel system. As aresult of the tests, it was made clear that the vortex-induced oscillation is controlled with large-scale turbulence flow.
