Lateral unrestrained steel beams when subjected to high temperatures may collapse in
service by lateral torsional buckling. This instability state may be predicted in the resistance …

The paper presents the development of a three-dimensional (3D) beam element for the
analysis of steel structures in fire that properly accounts for the degradation of the torsional …

Fire causes one of the worst hazardous situations to structures. With the increase in
temperature, there is a rapid decrease in steel material properties, which eventually leads to …

The local buckling behavior of hot-rolled and welded I-sections under simple load cases at
elevated temperatures is investigated numerically through extensive numerical analysis …

The steel sections are subjected to instability and buckling failure due to the rapid
degradation of flexural rigidity under fire-loading conditions. The behavior of monosymmetric …

A residual stress generated in the steel structure is broadly categorized into initial residual
stress during manufacturing steel material, welding residual stress caused by welding, and …

This paper presents an investigation on the influence of structural imperfections on the
ultimate load capacity of steel welded beam-columns with class 4 cross-section under …

As high strength steel (HSS) box columns are often fabricated by welding of steel plates
together, welding process during fabrication inevitably introduces residual stresses in the …

Several production processes, both conventional and innovative, may result in residual
stresses arising in critical areas of a component. The main issues include high distortion …

This paper presents the details and analysis of a fire test conducted on a stainless steel
cellular beam, as well as the development of a finite element model to further study the …
