- Buckling and Torsion of Steel Angle Section Beams
- Although steel single angle sections are commonly used as beams to support distributed loads, which cause biaxial bending and torsion, their behavior may be extremely complicated, and the accurate prediction of their strengths very difficult. In this paper, an approximate method of predicting the second-order deflections and twist rotations of...

- Biaxial Bending of Steel Angle Section Beams
- The loads applied to angle beams usually act out of the principal planes so that they cause simultaneous biaxial bending about both principal axes. This paper investigates the biaxial bending of unbraced steel angle beams. The biaxial bending of compact equal angles in uniform bending is considered first, and a...
