Finite element stability analysis of thin-walled steel structures [PDF]

Dynamic Stability of Monosymmetrical Thin-Walled Structures [PDF]

Journal of Applied Mechanics, Transactions ASME, 1972
A study is made on the dynamic stability of thin-walled beams of monosymmetrical cross section. Under the action of axial periodic loads, the parametric excitation of the coupled flexural-torsional type of vibrations is investigated.

Buckling Capacities of Monosymmetric I‐Beams

Journal of Structural Engineering, 1986
The paper examines the elastic lateral buckling of simply supported monosymmetric I-beams under ransverse loads. Solutions are obtained in terms of the easily evaluated degree of beam monosymmetry parameter, ρ, and the beam parameter, K. It was found that the moment modification factors of double symmetric I-beams presently used in design formulas to ...

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 ...
