ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Lateral torsional buckling of an I‐shaped hoisting spreader beam
I-shaped hoisting spreader beams are widely used in practice when lifting heavy objects by crane. In general, I-shaped beams that are subjected to a bending moment may be sensitive to lateral torsional buckling.

Torsional restraint against elastic lateral buckling [PDF]
It is well known that a central elastic torsional restraint restricts the lateral buckling shape of an elastic I-beam and increases its elastic flexural-torsional buckling resistance.

I‐shaped beams installed in a braced structure are subjected to reversed axial forces during earthquakes. Previously, we have derived the evaluation index and formulae for beams that collapsed with dominant local buckling.

Application of the Rayleigh quotient method in the analysis of stability of straight elastic bars [PDF]
The paper deals with stability problems of straight elastic bars made of a homogenous isotropic material. The approach concerns both the bars of compact cross-sections and of thin-walled cross-sections, the transverse distortions being neglected.

Lateral Torsional Buckling of Steel Beams under Transverse Impact Loading
This study employs experiments and numerical simulation to analyze the dynamic response of steel beams under huge-mass impact. Results show that lateral torsional buckling (LTB) occurs for a narrow rectangular cross-section steel beam under transverse ...

A mathematica code for evaluating lateral-torsional buckling of tapered cantilevers [PDF]
Lateral-torsional buckling (LTB) is the primary failure mode where slender cantilevers experience nonuniform twisting and buckling about their weak axes.
