Connections

Arc Welding – a process of welding that passes an electric current through a metal electrode that produces intense heat that melts and fuses the electrode rod as well as a small portion of the connecting elements
Beam Hangar – a steel connection that is used to anchor a flush/face beam connection
Bolt – a type of fastener that can resist withdrawal and lateral loads significantly more than nails and screws
Common Bolts (Unfinished Bolts, ASTM A307) – structural steel bolts composed of low carbon steel that have a smaller load capacity than high strength bolts
Direct Tension Indicator Bolts – a type of high strength steel bolt that releases silicone that is embedded in the depressions of the washer when the desired amount of torque is applied
Filet Weld – a type of weld that is used to join overlapping elements
Framing Anchors –
Groove Weld – a type of weld that is used between adjacent members
High Strength Bolts (A325, A490) – structural bolts composed of high strength steel that are tightened with an impact wrench to produce friction type connections
Impact/Torque Wrench – a wrench that can be calibrated to apply a specific amount on torque
Joist Hangar – a steel connection that is used to anchor a flush/face joist connection
Nail – a type of simple wood fastener used in small-scale construction that resists shear but does not resist tension forces
Post Base/Cap – a steel fastener used to anchor a post or column into the foundation and/or ceiling
Rebar Jacket
Rigid Connection – a type of structural joinery that resists both shear forces and bending moments
Rivet – a smooth, screw like fastener that is pushed through adjacent members and pneumatically hammered and heated to produce an anchoring head on the opposite side of the rivet head
Screw - a type of simple wood fastener that is somewhat more efficient than nails used in small-scale construction that resists shear but does not resist tension forces
Semi-Rigid Connection – a type of structural joinery that restrains translation and permits partial rotation of the connecting members
Simple Connection – a type of structural joinery that resists shear forces but does not resist bending moments
Twist Off/Tension Controlled Bolts – a type of high strength bolt that releases the splined extension of the bolt when the optimum amount of torque is applied
Welding – a method of joining steel elements by heat
Withdrawal Load
