A Study on Joint of Steel and Concrete Box Girder of Shi-banpo Bridge in Chongqing
In this paper,a finite element analysis model of Shi-banpo bridge is performanced to analyze response of the bridge corresponding to different load cases.At the same time,a local model of the joint of steel and concrete box girder is established,and a transition element between concrete and steel shear board is used to simulate the relative deformation.The strain and relative displacement of joint is analyzed under different load case.The limited values at different level of safety of the joint are also gain on the basis of the analysis results.Considering studies on the application at present,several sensors of strain are set in the concrete box girder,the steel box girder and the joint,and sensors of displacement are set between concrete and steel shear board.The conclusion of the paper can provide suggestions to the health monitoring and safety evaluate of this kind bridges.
