This paper investigates the inelastic lateral torsional buckling, LTB, of doubly stepped singly symmetric compact I-beams under two concentrated loads. The results are obtained by conducting actual destructive tests on the beams using a testing machine and running simulation tests using the finite element program, ABAQUS.

Abstract Elastic lateral-torsional buckling (LTB) is a common failure mode of large span beams. In this phenomenon the beam becomes unstable along the unbraced length. This instability of beams can be identified by out-of-plane deflection and twisting. Using discrete torsional braces is one of the ways to prevent LTB.

An Energy Approach to Elastic Stability Analysis of Multiply Braced Monosymmetric l-Beams
Mechanics of Structures and Machines, 1989ABSTRACT This paper investigates the elastic stability of multiply braced cantilevered and simply supported monosymmetric I-beams. On the basis of the Timoshenko energy approach, a generalized Rayleigh quotient is derived. The buckling capacity can then be obtained by solving an optimization problem in which the Rayleigh quotient (the objective ...

Distortional buckling strength of elastically restrained monosymmetric I-beams
Thin-Walled Structures, 1990Abstract An inelastic method of analysis of the distortional buckling of monosymmetric I-beams is augmented to include the effects of elastic restraints against translation, minor axis rotation, torsion and warping. The method is validated for problems for which inelastic, distortional and restraint solutions are known.

Abstract Finite element buckling analyses of monosymmetric I-beams subjected to transverse loading applied at different heights with respect to the mid-height of the cross-section were conducted. Transverse loads consisting of a mid-span point load and a uniformly distributed load were considered in the investigation. Four types of end restraint also
