Distortional buckling in monosymmetric I-beams

Thin-Walled Structures, 2006
This paper deals with distortional buckling of simply supported monosymmetric I-beams under three types of load: a central point load, a uniformly distributed load and a uniform sagging moment. ABAQUS is used for the investigation. Top-flange and bottom-flange load positions are considered for the first two load cases.

Instability of Monosymmetric I‐Beams

Journal of Structural Engineering, 1984
The elastic flexural-torsional instability of monosymmetric I-beams and cantilevers is investigated using a general energy approach based on the vanishing of the second variation of the total potential energy. For simply supported beams, closed form solutions are presented which are valid for a wide range of section properties and which include the ...

Inelastic Buckling of Welded Monosymmetric I‐Beams

Journal of Structural Engineering, 1987
The inelastic buckling of welded monosymmetric I-beams under uniform moment has been investigated. The assumed welding residual stress is based on the so-called "tendon force concept" developed by the Cambridge group. The residual stresses are shown to be dependent on the connecting plate sizes, weld areas, and the welding process. The assumed residual

Buckling of Monosymmetric I‐Beams under Moment Gradient

Journal of Structural Engineering, 1986
The paper investigates the elastic lateral buckling of simply supported monosymmetric I‐beams under moment gradient. Independent solutions are obtained using the finite integral method and the Rayleigh‐Ritz energy approach. The elastic buckling moments depend on the degree of beam monosymmetry, ρ, the beam parameter, K¯¯¯, ¯, and the end moment ratio ...

Instability of monosymmetric I-beams and cantilevers

International Journal of Mechanical Sciences, 1985
Abstract The elastic flexural-torsional or lateral instability of monosymmetric I-beams and cantilevers is investigated using a general energy approach based on the vanishing of the second variation of the total potential energy in which the buckling displacements are represented by trigonometric series.

Distortional instability of fabricated monosymmetric I-beams

Computers & Structures, 1988
An energy method is presented to determine the elastic critical moments of simply supported monosymmetric I-beams in uniform bending. The method is very efficient computationally, since it results in an eigenproblem for stiffness matrices of order four. The energy method is shown to agree very well with established results.

Elastic Behavior of Tapered Monosymmetric I-Beams

Journal of the Structural Division, 1975
The simultaneous differential equations for bending out of the plane of symmetry and for torsion of tapered monosymmetric I-beams are derived by considering the flange displacements. It is found that these equations are not independent because the shear center and the longitudinal centroidal axes are not parallel, and it is concluded that torsion is ...

Elastic Buckling of Tapered Monosymmetric I‐Beams

Journal of Structural Engineering, 1988
A finite‐element method of analysis is presented for the elastic flexural‐torsional buckling of non‐prismatic I‐section beam‐columns. The formulation presents a general approach to the problem, in which the coupling of torsion and bending is simplified by adopting the web mid‐height as an arbitrary axis of twist.

Timoshenko beam formulation for in-plane behaviour of tapered monosymmetric I-beams: Analytical solution and exact stiffness matrix

Thin-Walled Structures, 2021
Abstract The presence of curved centroidal axis in tapered monosymmetric I-beams results in coupling between the axial and flexural behaviours. In this paper, an extended Timoshenko beam formulation that incorporates the axial–flexure coupling in the governing differential equations is presented.

Inelastic Buckling of Monosymmetric I-Beams

Journal of the Structural Division, 1973
Considerations of flexural-torsional instability usually govern the design of laterally unsupported I beams. Numerous solutions for the elastic buckling of bisymmetrical I-sections under various loading and support conditions are currently available together with several extensions to cover inelastic behavior.
