On Lateral-Torsional Buckling of Non-Local Beams

Advances in Applied Mathematics and Mechanics, 2018
Nonlocal continuum mechanics allows one to account for the small length scale effect that becomes significant when dealing with micro- or nano-structures. This paper deals with the lateral-torsional buckling of elastic nonlocal small-scale beams. Eringen's model is chosen for the nonlocal constitutive bending-curvature relationship.

Simplified analytical method for lateral torsional buckling assessment of RHS beams with web openings

Structures, 2021
The present paper treats the lateral torsional buckling (LTB) of castellated rectangular hollow section (CRHS) beams. For the purpose, an analytical model was proposed to provide critical buckling loads in (LTB) resistance. In the present model two types

Experimental and numerical study on the lateral torsional buckling of full-scale steel-timber composite beams

Advances in Structural Engineering, 2021
The lateral torsional buckling (LTB) of steel-timber composite (STC) beam with partial interaction was investigated in this paper. The composite beam is constructed by connecting the timber to both flanges of the H-shaped steel with bolts or screws ...

Lateral–torsional buckling of steel beams pre-stressed by straight tendons with a single deviator

, 2021
We develop a novel lateral–torsional buckling theory for pre-stressed (PS) steel H-beams with or without a deviator by using the total potential energy derived from the second order terms of semi-tangential rotations, the analytically derived exact ...

Lateral–torsional buckling resistance of coped beams

Journal of Constructional Steel Research, 2005
The lateral–torsional buckling resistance of beams depends on the support conditions. In floor structures for buildings coped beams are often used. A numerical model was developed to investigate the influence of copes on the lateral buckling resistance.

Torsion equations for lateral buckling

Engineering Structures, 2016
Abstract A torsion differential equation previously used for analysing the elastic lateral buckling of simply supported doubly symmetric beams with distributed loads acting away from the centroidal axis omits an expected term and includes an unexpected term.

Lateral-torsional buckling of channel beams

Journal of Constructional Steel Research, 1990
A theoretical and experimental study of the buckling behaviour of channel beams with unbraced longitudinal edge stiffeners, bent in such a way that the stiffeners are in compression, is presented. For a relatively short length of beam loaded in such a manner, the beam will buckle symmetrically.
