This paper deals with change of buckling coefficients of symmetrically laminated reinforced concrete plates with a central rectangular hole under biaxial static compression loadings using finite element method. Composite structure of these plates has been constituted from four, six, eight and ten laminas including steel and concrete. The effect of change in central rectangular hole from the point view of size and direction on buckling coefficients is investigated in this study. Symmetrically laminated plates under biaxial in-plane loadings are taken into consideration in the analyses for simply supported and clamped boundary conditions. Obtained results are compared with each other according to a/L and b/L where a, b are the hole sizes and L is the length of the plate, respectively.
