Structural safety of rolled and welded beams subjected to lateral‐torsional buckling

Journal of Civil Engineering and Management, 2010
The expediency of using probability‐based approaches in the analysis of beams subjected to lateral‐torsional buckling is discussed. The values of buckling resistance moments and their uncertainties for rolled and equivalent welded I sections as ...

Lateral-Torsional Buckling of Beams Elastically Restrained Against Warping at Supports

Archives of Civil Engineering, 2015
The study presents the results of theoretical investigations into lateral torsional buckling (LTB) of bi-symmetric I-beams, elastically restrained against warping at supports. Beam loading schemes commonly used in practice are taken into account.

Lateral-torsional buckling of compressed and highly variable cross section beams

Curved and Layered Structures, 2016
In the critical state of a beam under central compression a flexural-torsional equilibrium shape becomes possible in addition to the fundamental straight equilibrium shape and the Euler bending.

Span-dependent comparative analysis of lateral torsional buckling and nonlinear load behaviour in castellated and solid I-beams using analytical and finite element approaches

Materials Research Express
Castellated beams (CB), widely employed in modern construction, offer an improved strength-to-weight ratio and enhanced structural efficiency due to their increased depth and moment of inertia.

A new finite element formulation for the lateral torsional buckling analyses of orthotropic FRP-externally bonded steel beams

Curved and Layered Structures
The present study develops a new finite element (FE) formulation for the lateral torsional buckling (LTB) analyses of steel beams exteriorly bonded with orthotropic fiber-reinforced polymer (FRP) layers.
