Lateral Torsional Buckling of Wood Beams

2014
Structural wood design standards recognize lateral torsional buckling as an important failure mode, which tends to govern the capacity of long span laterally unsupported beams. A survey of the literature indicates that only a few experimental programs have been conducted on the lateral torsional buckling of wooden beams.

Inelastic Lateral-Torsional Buckling of Beam Columns

Journal of the Engineering Mechanics Division, 1965
The problem of lateral-torsional buckling in beam columns is studied using an analytical approach to detect the stage at which the inception of this type of instability is imminent. The method adopted uses a forward integration scheme for solving the differential equations defining the problem.

Lateral-Torsional Buckling of Nonprismatic I-Beams

Journal of Structural Engineering, 1996
A finite-element formulation for the lateral-torsional buckling analysis of nonprismatic I-beams is developed. The formulation is capable of analyzing continuous I-beams with a linear or quadratic taper within acceptable accuracy. The influence of warping deformations of the section and location of the member loads at different cross-section points are

Lateral-torsional buckling of continuous bridge girders

Journal of Constructional Steel Research, 1998
Abstract The resistance of bridge girders with respect to lateral-torsional buckling at support is strongly influenced by the moment gradient. In most design methods this influence is taken into account by the use of a correct critical bending moment in the slenderness parameter λ. This critical moment is influenced by the shape of the moment diagram

Inelastic Lateral-Torsional Buckling of Beam-Columns

Journal of the Structural Division, 1966
A procedure for the determination of the inelastic lateral-torsional buckling strength of steel wide-flange beam columns is presented. The beam columns are subjected to axial thrust and to moments applied at one and only. The end moments cause bending about the strong axis of the members, and the effects of initially present symmetric thermal residual ...

Buckling curves for lateral torsional buckling of unrestrained beams

2007
In Eurocode 3 two methods to determine the ultimate lateral torsional buckling load of steel beams in bending are presented: the General and the Specific Methods. Both methods make use of buckling curves, but the curves to be used are different for both methods.

Lateral-Torsional Buckling of Tapered I-Beams

Journal of the Structural Division, 1981
The lateral-torsional buckling behavior of non-prismatic beams is not yet fully documented. Using the total change in potential energy during buckling, a fourth-order differential equation in the angle of twist, B, is obtained, in which the location of the transverse load with respect to the centroid is considered.

The buckling curve for lateral-torsional buckling resistance of castellated beams

2008
In determining the resistance of castellated beams to lateral-torsional buckling according to Eurocode 3 (EN 1993-1-1) the application of the appropriate buckling curve is crucial. The calculation resistance model to lateral torsional buckling is defined only for bending memebers of constant cross-section and for rolled I-sections (buckling curve a and

Improved Coefficients for Elastic Lateral-Torsional Buckling

46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005
of moment gradient due to dierent transverse loading and boundary conditions (Cb), and point of load application (Ca). These coecients are available in tabular form for a small set of common cases. Approximate models for the moment gradient coecient have been proposed but may have limitations. A simple but general method is presented for the evaluation

Flexural Strength for General Lateral–Torsional Buckling

Journal of Structural Engineering, 2007
The lateral–torsional buckling behavior of general prismatic and tapered steel members with doubly and singly symmetric sections are investigated based on the general forms of differential equilibrium equations for minor-axis bending and torsion. Fundamental lateral–torsional buckling moments are derived for general tapered steel members that are in ...
