Lateral-torsional buckling behaviour of concrete-filled high-strength steel tubular flange beams under mid-span load

, 2021
Lateral-torsional buckling (LTB) behaviour of concrete-filled high-strength steel tubular flange beams (HS-CFTFBs) is experimentally and numerically investigated. Six specimens are tested in simple support with a lateral unrestrained concentrated load in

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.

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 ...

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 ...

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

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.
