Abstract
In the hogging moment regions of steel–concrete composite continuous girder bridges, a detrimental condition appears such that concrete slab bears tensile stress and the steel girder bears compressive stress. Decreasing the shear connection in the hogging moment regions helps to improve the mechanical performance for steel–concrete continuous composite girder bridges. In this paper, analytical models for the calculation of composite girders considering partial shear connection (PSC) action are discussed. A project case of Qiwu Bridge in Jiangxi Province using partial shear connection action is introduced. A nonlinear finite element model of Qiwu Bridge is established through ABAQUS® to simulate and predict the mechanical properties and structural performance. Based on the finite element method results, the influence of PSC on various parameters is analysed by performing a parametric analysis. Numerical results show that arranging a partial shear connection region can effectively reduce the crack region and disperse areas having high stress concentration, but shear stiffness mutation can significantly increase the stress level at the edge of the partial shear connection region.
