A FORTRAN routine for computation of coupled bending-torsional dynamic stiffness matrix of beam elements

Abstract

A FORTRAN subroutine for computing coupled bending-torsional dynamic stiffness matrix of a uniform beam element is developed. An annotated listing of the program is presented. The application of the subroutine is discussed with particular reference to an established algorithm. An illustrative example on the use of the subroutine is given with representative results.
