In this parametric study, the buckling analysis of symmetrically laminated rectangular thin plates assumed to be subjected to biaxial compression was presented. The simply supported boundary condition was considered at the edges of the symmetrically laminated quasi-isotropic, cross-ply and angle-ply plates. The Rayleigh-Ritz Method was used to specify the critical buckling load of the plates based on the Classical Laminated Plate Theory (CLPT). A convergence study was achieved by increasing the number of parameters of assumed shape function. Validation of isotropic case was verified. The effects of the lamination types, plate aspect ratios (a/b, b/a) and thickness on the critical buckling load of the laminated plates under bi-axial compression were then investigated. The results were compared with Finite Element Method (FEM) solutions performed by ANSYS software package and fairly good agreement was obtained. Non-dimensional results were tabulated and presented for practical use for designers.
