Abstract: Box members formed by spot welding two thin-walled members of hat selection are widley employed in motor car frame structures. In particular, those members subjected to large bending loads are reinforced by sandwiching a longitudinal partition between the two hat members and spot welding to connect. This clarifies that although the partition increases the bending strength on the one hand, it tends to reduce the torsional rigidity.

Keywords: bending loads; box members; hat sections; spot welding; stress; torsional rigidity; automotive welding; automobile industry; boxbeams; vehicle frame structures; longitudinal partition; bending strength.
