摘要：

This paper investigates the effects of turbulence characteristics such as turbulence intensity and scale on vortex-induced oscillation of bridge girders with basic sections. The basic sections are selected taking into account of various effects of turbulences on vortex-induced oscillation such as; the maximum amplitude of vortex-induced oscillation is 1) reduced, 2) enlarged in some cases or 3) not changed by the existence of wind velocity fluctuations, which are referred from literature review. The vortex-induced responses of models are examined not only in grid-generated turbulent flows but also in actively simulated turbulences with large scale through an active gust generator. The effects of turbulence properties on vortex-induced response are evaluated in terms of the ratio of the maximum amplitude in turbulent flows to that in a smooth flow.
