VIBRATION ANALYSIS FOR FRAME STRUCTURES USING TRANSFER OF DYNAMIC STIFFNESS COEFFICIENT

In this paper, the authors formulate a free and forced vibration analysis algorithm for frame structures using the transfer dynamic stiffness coefficient method. This method is based on the concept of the transfer of the dynamic stiffness coefficient which is related to the force and displacement vector at each node from the left end to the right end of the structure. Numerical results by the transfer dynamic stiffness coefficient method for a space frame structure are compared with results by the finite element method and experiment. The validity and the convenience of the transfer dynamic stiffness coefficient method in solving dynamic problems accurately are confirmed.
