NONLINEAR FINITE ELEMENT ANALYSIS OF STEEL PLATE-CONCRETE COMPOSITE BEAMS

Based on the experimental study of eight Steel Plate-Concrete Composite (SPCC) beams, the numerical studies on the entire process of the loading and other structural behaviour in the flexural failure and steel plate bonding failure of SPCC beams are conducted in the platform of ABAQUS. The nonlinear behavior of materials, load-slip behavior and fracture model of studs are taken into account in the analysis. The results of the finite element analysis are found to be in good agreement with the experimental results. The main parameters affecting the behavior of SPCC beams are analyzed, including the thickness and the length of steel plate and the space between studs, etc. The result shows that the ultimate shear strength of studs should be reduced in design in order to make sure SPCC beams fail in flexural failure mode.
