The authors apply the transfer influence coefficient method to the in-plane flexural free vibration analysis of a structure with double layers regarded as a discrete system with lumped mass, lumped inertia moment, and massless linear and rotational springs. They describe an effective method of reducing the computation time for the structure in which the lengths of layers are remarkably different from each other, and a systematic and generalized treatment of the releases and rolls in each layer at which the displacements are discontinuous. The results of the comparatively simple numerical computational examples on a personal computer also demonstrate the validity of the present algorithm for the particular structure, that is, the numerical high accuracy, the high speed and the flexibility for programming of the present method, compared with the transfer matrix method.
