A COMPUTER PROGRAM FOR CALCULATING THE NATURAL MODES OF A NON-UNIFORM BEAM.

Abstract

A computer program for solving for the natural mode shapes and frequencies of a non-uniform beam is described and presented in this report. The matrix displacement, or stiffness, method is used to derive the beam-system mass and stiffness matrices. This formulation leads to 'consistent' mass matrix and stiffness matrices that include the effects of shear and rotatory inertia. The presence of structural joints may be included and almost any type of supports may be solved, including free-free, pinned, fixed, and elastic supports. (Author)
