Abstract

There is little advice available on how to design for torsion effects in steel structures, except by using elastic analysis and first yield design. However, elastic analysis is cumbersome and time-consuming, while first yield design for strength is unnecessarily conservative.

This paper develops a simple method of plastic analysis of compact I-section members in torsion, and shows how this can be applied in strength design to produce economical structures. A simple approximate method of elastic analysis for serviceability design is also presented.
