Elatic Bending and Buckling of Steel-Concrete Composite Plate Considering Slip Effect
Steel-concrete composite plates are formed using steel plates connected to a concrete slabs by means of welded stud shear connectors. The flexibility of connection between the steel plates and concrete gives rise to interface slip and additional deflection. An analytical model considering slip effect for composite plate is presented in this paper. Analytical solutions for deformation of composite plate under lateral load and elastic critical buckling load of composite plate under axial compressive load are deserved. The model and the solutions are then validated by means of finite element analysis. According to the parametric study, when impact factor greater than 5, the critical buckling load of simply composite plate is close to the superposition of the critical buckling loads of steel and concrete slabs and the interaction of both slabs can be ignored.
