Inelastic Lateral Torsional Buckling of Beams

Journal of the Structural Division, 1981
A numerical procedure is presented for predicting elastic and inelastic beam buckling loads. The procedure uses a finite difference solution to the differential equations defining lateral torsional buckling. The reduction in beam stiffness in the inelastic range is estimated by using an approximate tangent modulus method.

New method for metal beams sensitive to lateral torsional buckling with an equivalent geometrical UGLI imperfection

, 2021
The Eurocodes EN 1993-1-1:2005, prEN 1993-1-1:2020, and EN 1999-1-1:2007, prEN 1999-1-1:2020 propose the same method. They take into account the geometrical equivalent Unique Global and Local Initial (UGLI) imperfections.

Lateral-Torsional Buckling of Parabolic Arches

Journal of the Structural Division, 1972
Equations were derived which govern the lateral-torsional buckling of parabolic arches. Buckling loads were obtained for a uniform applied loading. Both free-standing and crown restrained arches with fixed and hinged end support were considered. A comparison was made, wherever possible, between some of the buckling loads calculated and existing ...

Lateral-Torsional Buckling of Stepped Beams

Journal of Structural Engineering, 2003
Continuous multispan beams with stepped cross sections at the interior supports are common in construction of steel buildings and bridges. Design equations for lateral-torsional buckling (LTB) resistance in the American Institute of Steel Construction LRFD Specifications in 1998 account for only prismatic and web-tapered beams.

Lateral-torsional buckling of cellular beams according to the possible updating of EC3

Journal of Constructional Steel Research, 2019
Researchers have not yet reached a consensus on which buckling curve to use for the calculation of the lateral torsional buckling (LTB) resistance of cellular steel beams in the current version of EC3.

Buckling of laterally and torsionally braced beams

Journal of Constructional Steel Research, 1988
Abstract This paper reports on a study of the buckling behaviour of simply supported beams under uniform moment. The beams are braced laterally and torsionally at midspan, and can be doubly-symmetrical or monosymmetrical. A closed-form solution is obtained, the relations between buckling moments and bracing stiffnesses are given and formulae for the ...

The lateral-torsional buckling of unrestrained steel beams in fire

Journal of Constructional Steel Research, 1996
A three-dimensional computer model which is capable of predicting the structural behaviour at elevated temperatures of skeletal steel frames has been used to investigate the ultimate behaviour of uniformly heated unrestrained beams. A series of different sections and spans has been studied for different loading patterns and load ratios.

Reassesment of lateral torsional buckling in hot-holled I-beams

, 2020
Lateral torsional buckling (LTB) of I-beams is characterized by simultaneous lateral deflection and twist. In this paper the influence of destabilizing and neutral effects of loadings and the possibility of the occurrence of web distortion, which ...
