Design of Fillet Welds to Rectangular HSS Steel Tube

The fillet weld design clauses in AISC 360 Section J2.4(a) permit the use of a so-­called directional strength enhancement factor for fillet welds (i.e. the 1.00 + 0.50sin 1.5 term in Equation J2-­5), which enables the weld strength to be enhanced when the direction of loading is non-­parallel to the axis of the weld. The adoption of the directional strength enhancement factor, or sin factor into AISC 360 was HOLLOW STRUCTURAL SECTIONS - Bull Moose TubeThe transformation of steel strip into hollow structural sections (HSS) is the result of operations including forming, welding and sizing. Currently three methods are being used in North America for the manufacture of HSS. These methods, including two ERW methods a

ISO - ISO 14347:2008 - Fatigue Design procedure for

ISO 14347:2008 gives recommendations for the design and analysis of unstiffened, welded, nodal joints in braced structures composed of hollow sections of circular or square shape (with or without rectangular chord) under fatigue loading. Rectangular, Square and Circular Steel Hollow SectionsSmooth uniform profiles of sections minimizes dust and moisture accumulation. By virtue of its shape Hollow sections have high Radius of Gyration resulting in higher concentric strength. compared to conventional sections., Due to closeness of the section there will be higher torsional rigidity Better lateral stability and lower wind drag. Steel Construction - SSAB4 Welding in the cold-formed corner area Rectangular hollow sections are well suited to the manufacture of welded structures. For historical reasons, there are concerns regarding the possible strain ageing caused by welding and hence the reduction in impact tough-ness of rectangular hollow section corners. Consequently, Eurocode 3 in-

Structural design using coldformed hollow sections

Rectangular Hollow Sections (RHS). Manufacturers of cold-formed structural hollow sections (CFSHS) are more numerous, so that their products are more widely available. Hot-finished structural hollow section (HFSHS) products are typically between 24 % and 54 % more expensive in Germany than their cold-formed counter- Structural hollow sections - SSAB - SSABStructural hollow sections SSAB produces cold-formed and welded structural hollow sections for multiple purposes, ranging from versatile SSAB Domex Tubes to ultra-high-strength Strenx Tubes. Whether you are building lifting or moving equipment or designing buildings, you can find a Technical Cold formed sections - newsteelconstructionThis does not apply however to cold formed square and rectangular hollow sections, which experience significant strains at the corners of the profile. Neither does it apply to beams which have been pre-cambered by cold bending. The product standard for cold formed welded structural hollow sections, BS EN 10219-1:2006 requires that for square or
