The present paper proposes an integral equation formulation for static bending and its implementation of stiffened-anisotropic plates using boundary element method. For an eccentrically stiffened plate, in-plane and out-of-plane deformations are coupled. It implies that the bending and plane-stress deformation of the elastic plate should be considered together with tensile, bending and twisting deformation of the stiffener. In this paper, three components of interactive force and two components of interactive moment between the plate and stiffener are treated as line distributed unknown loads. The numerical results obtained by the computer code developed in this study are discussed, whereby the versatility of the proposed method of analysis is demonstrated.
