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.

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 ...

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 ...

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.

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.

Lateral–torsional buckling of I-girders with discrete torsional bracings

Journal of Constructional Steel Research, 2010
Abstract Discrete torsional bracing systems are widely used in practice to increase the lateral–torsional buckling (LTB) strength of I-girders. However, only limited studies are available on the LTB strength of I-girders with mid-span torsional bracing.

Modelling and Statistical Approaches to Lateral-Torsional Buckling

Advanced Materials Research, 2014
Some particular and selected problems aimed at ultimate limit state and probability-based studies pertaining to lateral-torsional buckling of steel beams are described. Stochastic analysis of the ultimate limit state of a slender member IPE220 under bending was elaborated.

On the lateral-torsional buckling of non-uniform C-beams

2019
This paper experimentally and numerically investigates the lateral stability problem of metallic C-beams with uniformly varying cross-section. The results of a compression test on a physical model are compared with the numerical predictions of the lateral-torsional buckling load given by a variational approach. A good theory vs.
