Abstract
This paper presents a new method, termed modal perturbation combined m ode superposition and matrix perturbation, of nonlinear response analy sis for large deflection forced vibration of beams subjected to period ic laoding. Longitudinal displacement and inertia are both considered in the formulation. As an application of the method, a numerical examp le is given. The results show that the modal perturbation proves to be effective in this class of problem.
