1 Introduction
The present paper proposes an integral equation formulation for elastostatic defor-
mation problem of eccentrically stiffened plates. Though some boundary element
analysis of stiffened plates have been proposed so far [1, 2, 3, 4, 5], many of
them consider only concentrically stiffened plates. In case of such eccentrically
stiffened plates, in- and out-of-plane deformation of the stiffened plate are cou-
pled. Previous studies on concentrically stiffened plates by the boundary element
method were based on the Timoshenko theory of elastically supported plates [6],
where the equivalent shear force acts as distributed force on stiffener (rib), and
the bending moment as distributed twisting moment. This theory requires that the
centroidal axis lies in the middle p
