Abstract: An analysis method for steel-concrete composite plate is presented, with stud-slip effect considered. A hypothetical thin shear-layer between steel and concrete slabs is employed to model the shear deformation. Analytical solution for deformation of composite plate under uniform loading and elastic buckling critical-load of composite plate under axial compression are derived. The model and the solution are then validated by means of finite element analysis. A parametric study demonstrates that, for simply supported rectangular composite plate, if , the critical-load can be predicted by simply adding the contributes of steel and concrete slabs, and the interaction between them can be ignored.
