This work aims to study the effect of cold forming on texture evolution during manufacturing rectangular hollow sections. Conventional TMCP steel and a direct-quenched in 420 MPa strength level are compared. The was characterized at centerline (S=0) both surfaces (S=0.8) for base material, four flat side one corner samples section. results show that sides steels have minor intensity ∼{554}<225>...

The elliptical hollow section has been recently included in the family of structural steel sections. This type is also used production concrete-filled tubular (CFST) members. For CFST compression members, there no specific design formulation current provisions, except code called “Technical for structures” prepared by Ministry Housing and Urban-Rural Development People’s Republic China. However...

Abstract This paper presents the results of a theoretical-numerical study laterally-restrained thin-walled steel rectangular hollow flange beams subjected to bending, shear and bending interaction. Finite element analyses were carried out by using ANSYS software, validated previous experimental tests. Furthermore, effect intermediate stiffeners was investigated, where improvement percentage in ...

This paper reports an experimental and numerical study of the cross-sectional behaviour cold-formed high-strength steel (HSS) square rectangular hollow section (SHS RHS) members. Six stub column tests, six 3-point three 4-point bending tests have been carried out, followed by development accurate finite element (FE) models a parametric study. Based on test FE results, design rules for slender c...
