Abstract
The study examines the shear behaviors in girder bridges with corrugated steel webs (CSWs) considering different boundary constraints through theoretical analysis, experimental investigation, and numerical simulation. The accordion effect significantly amplifies shear deformation in CSWs at support locations. The substantial difference in shear stiffness between the CSWs and the concrete slabs constrains the shear deformation of CSWs, resulting in the generation of additional shear force within the CSWs. Therefore, the existing basic shear method is inaccurate for calculating shear stress in CSWs because it neglects this influencing factor. The study proposes an advanced formula for accurately predicting shear stresses near the supports of a cantilever prismatic girder bridge with CSWs by incorporating the additional shear forces induced by the shear deformation of CSWs. Theoretical analysis has revealed that the expression and magnitude of the additional shear force are correlated with the boundary conditions of the girder bridge. The study formulates expressions for the additional shear force induced by shear deformation in girder bridges with CSWs, considering various boundary conditions such as cantilever, simply supported, fixed-end, and continuous spans. It contributes to further enhancing the analytical method for calculating shear stress in prismatic girder bridges with CSWs, accommodating diverse support constraint conditions. The findings have practical implications for guiding the shear design of girder bridges with CSWs under various support systems.
