✦ Synopsis

A new general beam sti ness matrix which accounts for bending, torsion and shear deformation is derived from an elasticity solution of the beam. The in uence of shear and torsion is considered using a 3 × 3 matrix of deformation coe cients. Numerical examples are presented to demonstrate the behaviour of the deformation coe cients and of the beam sti ness matrix.
