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 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

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 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 ...

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 ...

Simplified numerical model development for advanced design of lightweight-concrete encased cold-formed steel shear wall panels

SN Applied Sciences, 2023
Since cold-formed steel (CFS) elements are susceptible to complex buckling phenomena that decrease their structural capability, many strengthening trends have been developed so far.

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 ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
