抄録

For the control of structure-borne sound, the evaluation of the propagation properties of the vibration in buildings is very important. In this paper, a method for the calculating the complex amplitude of vibration acceleration in three-dimensional framed structures is described. It deals with quasi-longtunaidal waves and bending waves. Wave transmission theory and the Lagrange's equation are used to formulate motional equations and energy equivalence equations for an element. A simulation and a model test were performed, the analyses and the measurements corresponded satisfactorily.
