Pure torsional buckling
WebThis program analyzes rolled AISC steel W, H, S, M, C, B, JR, and MC I sections and channels subjected to applied loads causing torsion within the beam. Both plane and bending stresses are determined in addition to typical AISC code checks for compactness and lateral-torsional buckling. Two end fixity combinations are allowed to separately ... WebThe work reported in this paper is a sequel of previous numerical investigations carried out by the authors on the post-buckling behaviour, strength and Direct Strength Method (DSM) design of cold-formed steel (CFS) fixed-ended plain and lipped channel columns (both singly-symmetric with respect to the major-axis) buckling in flexural–torsional modes and …

Lateral torsional buckling is not possible to occur if. a) moment of inertia about bending axis is twice than moment of inertia out of plane. b) moment of inertia about bending axis is greater than moment of inertia out of plane. c) moment of inertia about bending axis is equal to or less than moment of inertia out of plane.
The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). This ratio affords a means of classifying columns and their failure mode. The slenderness ratio is important for design considerations. All the following are approximate values used for convenience.
