HSS Limit States in Cap Plate Connections Steel Tube Description

HSS Splices Steel Tube Institute

Standard methods for bolted shear connections apply, using the applicable limit states in AISC 360-10 Chapter J, but one should always only design for the applied load(s) on the connection. Since bolt holes reduce the HSS net cross-sectional area the limit state of HSS net section fracture may govern over gross area yielding, thus illustrating HSS Limit States in Cap Plate Connections Steel Tube What is a HSS member?What is a HSS member?Identical, or similar-sized, HSS members frequently need to be joined end-to-end, or spliced, particularly in long-span construction and in tall columns. The familiar steel construction maxim of weld in the shop, bolt in the field, naturally applies.HSS Splices Steel Tube Institute

What is structural welding?What is structural welding? Structural welding is a process whereby the parts to be connected are heated and fused with a molten filler metal. Upon cooling, the structural steel (parent metal) and weld or filler metal will act as one continuous part.  The filler metal is deposited from a special electrode.Structural Steel Connections, Joints Details10.11 Design of HSS and Box Member Connections on HSS
