Lateral distortional buckling in steel-concrete composite beams: A review

Structures, 2020
Abstract Steel-concrete composite beams, when requested by negative moment, can fail due to Lateral Distortional Buckling (LDB), local buckling, by a combination of these stability modes or achieve the plastic behavior. LDB is a mode of stability in which the web must distort in order for the compression flange to displace and twist during buckling ...

Numerical assessment of lateral distortional buckling in steel-concrete composite beams

Journal of Constructional Steel Research, 2020
Abstract Steel-concrete composite beams, when requested by negative moment, can fail due to Lateral Distortional Buckling (LDB), local buckling, or by the combination of these stability modes. LDB is a mode of stability in which the web must distort in order for the compression flange to displace and twist during buckling.

Assessment of lateral distortional buckling resistance in welded I-beams

Journal of Constructional Steel Research, 2020
Abstract Lateral distortional buckling (LDB) of I-beams is characterized by simultaneous lateral deflection, twist and cross section change due to web distortion. The present study investigates the effect of web distortion in LDB resistance of doubly-symmetric welded I-beams.

An Analytical Solution for the Elastic Lateral-Distortional Buckling of I-section Beams

Advances in Structural Engineering, 2004
Lateral-distortional buckling may occur in I-section beams with slender webs and stocky flanges. A computationally efficient method is presented in this paper to study this phenomenon. Previous studies on distortional buckling have been on the use of 3rd and 5th order polynomials to model the displacements.

Lateral–distortional buckling of hollow tubular flange plate girders with slender unstiffened webs

Engineering Structures, 2013
Abstract In this paper, the lateral–distortional buckling (LDB) of hollow tubular flange plate girders (HTFPGs) with slender unstiffened webs is investigated. Firstly, shell finite element analyses are performed in order (i) to study the elastic buckling behaviour of simply supported HTFPGs under uniform bending and (ii) to compare it with the ...

Lateral–distortional buckling of I-beams and the extrapolation techniques

Journal of Constructional Steel Research, 2008
Abstract Various extrapolation techniques are utilized for predicting the critical buckling load of structural members undergoing lateral buckling. For the application of these methods it is only necessary to have data relating load to a deformation characteristic.
