Warping torsion of non-uniform thin-walled open section at cantilever beams

Abstract

The problem of torsion of the I-section beam is considered in this work, with emphasis on the variable cross section of the beam. Linear variation of height is concerned as most practical one for the design of cantilever beams. The solution for adopted cases of beams is obtained numerically, according to the given ordinary differential equation which deals with pure torsion along with warping torsion. The models are based on practical tailore-made beams. The comparison of results is done with uniform cantilever beam models which can be used as one view for stress check of cantilever beams subjected to bending with torsion.
