Study on Influence of Temperature to Section Deformation of Steel Box Girder during Cantilever Installation

Zhong San Li, Jun Lei, Kun Zhang, Yun Ya Xiao, Dao Jin Lin

Abstract

Because of solar radiation and the atmospheric temperature rise, the temperature change of the steel box girder bridge be larger. Thermal conductivity and sensitivity to the temperature change of steel is very good. The impact of temperature effect can be compared with the dead and live load under certain circumstances. Taking a bridge as example, the relative deformation of flat steel box-shaped girder is analyzed with the finite element analysis software. The results can be reference for other bridges.
