RETRACTED: Study on Mountain Wind Environment and Buffeting Response of Large Steel Truss Arch Bridge (Retracted Article)

At present, the wind resistant studies for the bridge are mainly aimed at the open plain areas, but the wind resistant studies, functioned by the complex wind at the western mountain, are seldom made. Thus, taking the Chongqing Daning River Bridge for the object in this paper, the environmental characteristics of the wind at the Daning River Bridge are obtained firstly through field measurement, including basic wind speed, wind profile, turbulence intensity, fluctuating wind power spectral density function as well as turbulence integral scale and other parameters. Then, through the numerical analysis, the buffeting forces and the response values on the full bridge are calculated. (C) 2011 Published by Elsevier Ltd.
