An analytical method of structural shape, which belongs to the inverse problem in the field of structural analysis, is presented under the prescribed displacement mode. First, the loaddisplacement relation whose coefficient matrix is a function of an unknown position vector representing the structural shape, and the subsidiary condition for the prescribed displacement mode are formulated. Then, these two equations are analytically analyzed by using the-Bott ・ Duffin inverse matrix. The obtained nonlinear equation which is a function of a position vector is numerically analyzed by Newton-Raphson method and by steepest descent method. Numerical examples show the varidity of the proposed method.
