TR14 Designing for Lateral-Torsional Stability in Wood Members

www.awc.org pdf codes-standardsLateral-torsional buckling is a limit state where beam deformation includes in-plane deformation, out-of-plane deformation and twisting. The load causing lateral instability is called the elastic lateral-torsional buckling load and is influenced by many factors such as loading and support conditions, member cross-section, and unbraced length.

What is a laterally supported beam? - Quora

www.quora.com What-is-a-laterally-supported-beamThe lateral support of a beam refers to any sort of restraint that can restrict the movement predominantly translation, but rotation as well of the compression section of a beam. A beam with such supports along the span can be considered a laterally supported beam and the effective span for LTB is reduced as the length between these supports.
