The residual stress in steel structural elements has significant influence on the flexural buckling behaviour of compressed members. This phenomenon causes that hot-rolled, cold-formed and welded sections with the same geometry have different flexural buckling behaviour and resistance. Previous research ...
prestressed tendons in corrugated steel web composite beam,the flexural tests of external prestressed corrugated steel web composite beams were carried out,and a nonlinear numerical model was established to study the influence of various parameters on the ultimate stress increment of prestressed tendons. ...

flexural bucklingresidual stressAyrton‐PerryWith the increasing application of high-strength steel over the past years, the urgent problem is to determine buckling curves in current codes for design of axial compression columns fabricated by high-strength steel. The current design curves cannot cover ...
The research reveals the influence of two commonly used steel fiber aspect ratios (50, 70) and steel fiber dosages (30 kg/m3, 40 kg/m3, 45 kg/m3) on the changes of the internal temperature field, the initial crack flexural strength and the flexural toughness of the SFRC com...
