ANALYSIS METHOD OF SOLID PROPAGATION VIBRATION

摘要

PROBLEM TO BE SOLVED: To provide an analysis method of solid propagation vibration capable of precisely analyzing in a short time even on a large scale structure.SOLUTION: The analysis method of solid propagation vibration includes the steps of: modelling a structure Bldg in a one-dimensional element Bm and a two-dimensional element P parallel to the one-dimensional element Bm; discretizing modeled one-dimensional element Bm and the two-dimensional element P into plural cells at each cross section perpendicular to a longitudinal direction of the one-dimensional element Bm; and calculating the vibration propagation based on displacement, rotation angle, bending moment and shear force which are generated by predetermined external force at the connection part between the discretized one-dimensional element Bm and two-dimensional element P.
