One of the difficulties encountered in making a dynamical model of a real structure is to determine the boundary conditions. As a means to determine boundary conditions, many experimental identification techniques have been proposed. However, many of them require measurements of the responses at the boundaries, which is often difficult in practice. Also many are applicable only to linear boundary conditions, which is a restriction. As a basis for developing a technique free from measurements of the responses at the boundaries and applicable to nonlinear boundary conditions, one of the authors took up a beam and developed a new technique based on the analytical solution. In this paper, by introducing the finite element method, we generalize the technique so that it can be applied to any nonuniform beams. By a numerical simulation we confirm the applicability of the proposed technique.
