Lateral distortional buckling of cellular composite-beams [PDF]
Revista IBRACON de Estruturas e Materiais, 2018 In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global

The Lateral Distortional Buckling of I-Plate Girders [PDF]
Journal of Engineering Research - Egypt, 2019 This paper presents a numerical study for lateral distortional buckling of I-plate girders (LDBIPGs) by using the general-purpose finite element package ABAQUS (version 6.13) software. 3-D finite element (FE) models for simply supported IPGs subjected to

Lateral-distortional buckling of continuous steel-concrete composite beam [PDF]
Revista IBRACON de Estruturas e Materiais, 2018 In hogging bending moment regions of continuous composite beams the collapse by lateral-distortional buckling (LDB) can occur. The design against LDB according to ABNT NBR 8800:2008 begins with the determination of the elastic critical moment, which ...

Lateral Distortional Buckling Resistance Predictions of Composite Alveolar Beams: A Review
Buildings, 2023 Few studies have investigated the structural behavior of steel-concrete composite alveolar beams in hogging bending regions. Their resistance can be reached by lateral distortional buckling (LDB), coupling LDB and local failure modes, or limit states of ...

Lateral distortional buckling tests of a new hollow flange channel beam
Thin-Walled Structures, 2011 The LiteSteel beam (LSB) is a new hollow flange channel section developed by OneSteel Australian Tube Mills using their patented dual electric resistance welding and automated continuous roll-forming process. It has a unique geometry consisting of torsionally rigid rectangular hollow flanges and a relatively slender web.

A Parametric Study on the LDB Strength of Steel-Concrete Composite Beams
Eng, 2023 Lateral distortional buckling (LDB) is an instability phenomenon characteristic of steel-concrete composite beams (SCCB) that occurs in the presence of hogging moments in regions close to internal supports.

Effect of web stiffeners on the lateral distortional buckling of channel section with hollow flanges
Ain Shams Engineering Journal, 2022 Hollow Flange Channels (HFC) have been known for their higher capacity when compared to open flange C-sections. On the other hand, the small stiffness of HFC slender web compared to their flanges limits the bending capacity to the lateral distortional ...

Web Rotational Stiffness of Continuous Steel-Concrete Composite Castellated Beams
Fracture and Structural Integrity, 2019 Continuous composite beams may suffer a global instability know as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment to LDB ...
