the section would effectively be in uniform torsion and warping moment would unlikely to be significant from the designer's perspective. Examples of this behaviour are closed hot-rolled sections (e.g. rectangular or square hollow sections) and rolled angles and Tees. Note that warping moment is developed only if warping deformation is restrained.

Compression Members Local Buckling and Section

(a) Rolled I-section (b) Hollow section Flange (c) Welded box section Internal Outstand Internal Web Figure 1 - Internal or outstand elements As the plate elements in structural sections are relatively thin compared with their width, when loaded in compression (as a result of axial loads and/or from bending) they may buckle locally. Design of steel footbridges - SteelConstructionfoHollow sections have been used for footbridges for over 50 years and some fabricators have specialised in this form of construction, developing techniques and details which utilise them to the best advantage. Vierendeel girders using hollow section members offer an alternative but complementary structural form of similar proportion by substituting a rectangular form for the triangular arrangement used in Factory Lower Price Hot Rolled Forged Steel Bar 42CrMo Steel Bar, Round Bar, Steel Rod manufacturer / supplier in China, offering Factory Lower Price Hot Rolled Forged Steel Bar 42CrMo 4140 Alloy Steel Round Bars, China Q235 Q345 Square Tube 38*38 Steel Pipe Ms Hollow Section Rectangular, China Pre-Galvanized Steel Pipe Gi Steel Tube and so on.

Full-Scale Tests of Butt-Welded Splices in Heavy-Rolled

Structural steel sections in Groups 4 and 5 are extensively used as compression members in tall buildings and other large structures. In a number of instances, welded butt splices in tension members fabricated from Group 4 and 5 sections would appear to provide a good solution to common design problems.

Welding Considerations for Designers and Fabricators

Is welding an issue when specifying Hollow Structural Sections (HSS)? According to section 12.5 of the new design guide:Hollow Structural Shapes (HSS) are an increasingly popular struc-tural material, offering many structural and architectural advantages. Connection detailing, fabrication practices, and inspection proce-HSS American Institute of Steel ConstructionJan 01, 2006 · HSS. Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085. The use of HSS is growing with popularity all around the world in the building industry and in the United States accounts for approximately 18% of the structural
