A buckling analysis method for moderately thick general triangular plates with anisotropic material properties and different boundary conditions subjected to combined in-plane loading has been developed using a first-order shear-deformation theory (FSDT). The analysis method is based on a Rayleigh-Ritz method and a variational formulation. Numerical results are obtained for various triangular geometries with isotropic and anisotropic material properties. The direction of the in-plane shear load is studied for different triangular geometries and degrees of material anisotropies. The symmetry of the triangular plate geometry seems to influence the buckling load more than the degree of material anisotropy for the cases considered in this study. The effect of transverse-shear deformation is studied for different triangular geometries, which confirms the importance of including these effects in the buckling analysis of composite plates. The present analytical formulation provides accurate buckling load results for isotropic and anisotropic triangular plates and will be useful in the preliminary design of grid-stiffened structures.
