Because of their high specific strength, stiffness and lightweight character, carbon fiber-reinforced plastics are beginning to be used as primary structures mainly in the field of aerospace, and hence the analysis of thin laminated structures is of great importance. In this paper, the post-buckling behaviors of quasi-isotropic laminated curved plates with initial deflection, which are simply supported along four edges, under uniaxial compression are examined by various methods including Galerkin's method In addition, secondary buckling phenomenon which is a unstable phenomenon of post-buckling is consider, using the second variation method which is determine stability of the total potential energy. Then, the effect which the shape parameter, laminated constitution, initial deflection give to the post-buckling behavior and secondary buckling is analytically examined and the other of various factors on the secondary buckling values are also clarified.
