Typical Steel Connections
Dr. Seshu Adluri
Steel Connections -Dr. Seshu Adluri
Introduction
Steel ConnectionsMany configurations are used for force transfer in connections. The configuration depends upon the type of connecting elements, nature and magnitude of the forces (and moments), available equipment, fabrication and erection considerations, cost, etc.

Steel Framing Connections
Framed ConnectionsBolts only in web, not the flangesTransmits only shearNot bending momentAccomplished with
� clip angles & bolts/welds
Moment ConnectionsTransmit shear & momentFlanges must be connectedBolt/Weld FlangesMay require column stiffeners
Steel Connections -Dr. Seshu Adluri
Framed connections
Only shear transferEquivalent to pinned end for the beamNo moment at the beam endRotation is freely (?) allowed
Steel Connections -Dr. Seshu Adluri
Framed connections
End reaction only Web of the beam is connectedNo connection for the flanges

Steel Connections -Dr. Seshu Adluri
Beam to Column Rigid JointsThe bending moment of the beam is primarily taken by the flanges in the form of tension and compression forces

Beam to Column Rigid JointsStiffener plates are used to ‘shore up’the column flanges against the forces transmitted by the beam flanges. The stiffeners may be full length or may extend only part of the column web depth.

Beam to Column Rigid JointsThe bending moment of the beam is primarily taken by the flanges in the form of tension and compression forcesThe bending moment of the column is also resolved as a force couple
