An initial stability of internally supported Kirchhoff plates has been analysed in the paper. Using the proposed approach, there is no need to introduce Kirchhoff forces at the plate corner and equivalent shear forces at the plate boundary. Two unknown variables are considered at the boundary clement node. The boundary integral equation is derived using the Bettie theorem. The collocation points arc located slightly outside the plate boundary, hence the quasi-diagonal integrals of fundamental functions are non-singular. The constant type of boundary clement is used.
