Plastic-Collapse Analysis of Torsion

This paper is concerned with the plastic-collapse analysis of structural steel I-section members subject to torsion. It proposes and exemplifies a method of plastic-collapse analysis that is much simpler than elastic analysis. The load factor at plastic collapse is obtained from the sum of the independent load factors for uniform-torsion plastic collapse and warping-torsion plastic collapse. This plastic-analysis method allows a method of plastic design to be used for torsion that is much simpler and more economical than first yield design. The use of plastic analysis and design will facilitate the design of steel torsion members and lead to more economical structures.
