Abstract

This paper presents theoretically the torsional inertia moment for open thin-walled rod, based on the theory of thin-walled shell. In the deduction, the rigid contour hypothesis is adopted and the cross-sectional warp is taken into account. With the above torsional inertia moment obtained and using the similar method for closed beam elements in Reference [1], the stiffness matrix of thin-walled beam element with open cross-section is derived with the warping of cross-section considered. Other than the traditional stiffness matrix of beam element having twelve DOFs, i.e. six for each node, this stiffness matrix is corresponding to fourteen DOFs, i.e. seven for each node. This matrix could be used for the finite element analysis of open thin-walled rod, with section warping considered.
