Lateral Distortional Buckling: Predicting Elastic Critical Stress

Journal of Structural Engineering, 1988
The problem of restrained lateral beam buckling is being treated in this paper. The restraint represents complete lateral and arbitrary continuous rotational restraint of one flange, the latter is represented by the spring stiffness \IC\N\d0. A simple theory, in which the problem is transformed into an ordinary fourth order differential eigenvalue ...

Distortional Buckling Solutions for Continuous Composite Beams

Journal of Structural Engineering, 1992
The paper presents a theoretical analysis of fixed-ended composite steel-concrete beams, representative of members continuous over an internal support. The analysis is elastic, and allows for the variation of sagging and hogging bending along the member.

Elastic distortional buckling of tapered composite beams

Structural Engineering and Mechanics, 1997
The overall buckling mode in a composite steel-concrete beam over an internal support is necessarily lateral-distortional, in which the bottom compressive range displaces laterally and twists, since the top flange is restrained by the nearly rigid concrete slab.

Compression tests of longitudinally stiffened plates undergoing distortional buckling

Journal of Constructional Steel Research, 2010
<p>This paper describes a series of compression tests performed on longitudinally stiffened plates fabricated from mild steel plates of thickness 4.0 mm with nominal yield stress of 240MPa. The stiffened plates with a range of rigidities of longitudinal stiffeners were tested to failure. The ultimate strength and performance of the longitudinally

Distortional lateral torsional buckling of beam-columns including pre-buckling deformation effects

Computers & Structures, 2018
Abstract The present study develops a unified distortional lateral torsional buckling finite element formulation for the elastic analysis of beam-columns with wide flange doubly symmetric cross-sections. The solution captures several non-conventional features including the softening effect due to web distortion, the stiffening effect induced by pre ...

Elastic distortional buckling of tee-section cantilevers

Thin-Walled Structures, 1999
The paper presents the results of a finite element study of the elastic distortional buckling of tee-section cantilevers, which can be thought of as beams fully braced at one end and unbraced at the other. The finite element procedure is described briefly, and then three loading cases, viz., a tip moment, a tip load and a uniformly distributed load are

Design for distortional buckling of flexural members

Thin-Walled Structures, 1997
Abstract For thin-walled flexural members composed of high-strength steel and/or slender elements in the section, a mode of buckling at half-wavelengths intermediate between local buckling and flexural—torsional or flexural buckling can occur. The mode is most common for edge-stiffened sections such as C- and Z-purlins, and involves rotation of the ...

Parameters Affecting Distortional Buckling of Tapered Steel Members

Journal of Structural Engineering, 1994
A finite‐element method of analysis for the elastic distortional buckling of doubly symmetric tapered I‐section beam‐columns has been modified to consider the effects of off‐shear center loading and discrete elastic restraints applied anywhere in the cross section or along the length of the beam‐column.

Distortional Buckling of Steel Storage Rack Columns

Journal of Structural Engineering, 1985
A distortional mode of buckling is described for cold-formed lipped channel columns that have additional flanges attached to the flange stiffening lips. The purpose of the additional flanges, called “rear flanges,” is to permit bolting of braces to the channel section so as to form upright frames of steel storage racks.
