The present report describes an application of the method (growth-strain method) previously proposed for analysis of uniform-strength shape with the finite-element method to the problems of steady-state vibration, especially free vibration with a normal-mode shape and response to a harmonic excitation. A difference in the implementation of the method for these vibration problems from the method for static problems is to analyze growth-measure(strength-parameter)distribution on the deformation with normal mode or amplitude of a response. Numerical experiments are made on simple beam structures. In the Case of normal-mode vibration, monotonous convergence is constantly observed. On the harmonic response problem, while the natural frequencies do not vary monotonously, the maximum value of the strength parameter, the mass and deflection at the excitation point converge monotonously.
