Abstract: Designing rigid and durable steel girder-to-concrete column connection is important for a new type of highway bridge constructed using a cantilever-erection method. To develop a full strength of the hybrid connection, the perforated steel plate is applied as a bonding means for the steel-concrete interface. A nonlinear finite element program has been developed to investigate the inelastic response of the steel-concrete hybrid structure. The model considers the essential nonlinearities arising in the materials: 1) nonlinear behavior of concrete under multiaxial stress states; 2) tensile cracking of concrete; and 3) elasto-plastic behavior of steel plates and reinforcing steel bars. Special attention has been paid to the two-dimensional nonlinear effect of perforated steel plates at the steel-concrete interface. Effectiveness of the analysis method is demonstrated through comparison of measured and numerical results on a highway bridge which has been constructed recently in Japan. It is followed by the analytical confirmation of the ultimate strength and deformation characteristics for a prototype connection region.
