Splice Connections
Used to connect two steel members end-to-end; facilitates transportation and handling of long members; requires careful alignment and fitting.
Moment Connections
Designed to transfer bending moments between members; allows restricted movement at the joint; typically used in beam-to-column connections in rigid frames.
Gusset Plates
Steel plates used to connect beams and columns at different angles; distributes stresses across the connection; commonly found in trusses.
Flange Plate Connections
Use steel plates welded to flanges of beams and columns; facilitates larger transfer of moments; suitable for high load situations.
Sleeve Connections
Hollow steel cylinders used to connect beam ends; beams are slotted into the sleeve and welded or bolted; used when a flush finish is needed.
Welded Connections
Created by welding two steel parts together; provides a strong and rigid connection; often used for permanent joints and in areas with restricted access.
Riveted Connections
Historic type of connection using rivets; requires heating and hammering; mostly replaced by bolted or welded connections nowadays.
End Plate Connections
Steel plate welded to the end of a beam, which is then bolted to another member; useful for site connections; efficient for transferring loads.
Stiffener Plates
Additional plates welded inside a steel member to strengthen or stiffen it; important in regions of high stress or to prevent local buckling.
Bearing Connections
Connection type where the load is transferred through bearing on the material; common in bridge beam ends or where shear is predominant.
Web Plate Connections
Steel plates connected to the web (vertical part) of a beam; used when flange connections are not practical or additional web strength is needed.
Base Plate Connections
Steel plates used to distribute column loads to a concrete foundation; typically anchored with bolts and may include leveling plates for alignment.
Tension Connections
Engineered to primarily resist tensile forces in a structure; can use rods or cables with eyes, forks, and other tension systems.
Compression Connections
Built to transfer compressive forces between structural elements; similar detailing as tension members but without risk of buckling.
Bolted Connections
Use bolts to fasten steel members; applicable for temporary or permanent connections; easily assembled and disassembled.
Shear Connections
Designed to resist shear forces; allows some rotation; typically beam to column connections where moment transfer is not critical.
Slotted and Oversized Holes
Allow for tolerance in the alignment of bolted connections; used in high-adjustability situations like steel framing installation.
Pin Connections
Use a steel pin to connect members at a joint; allows rotation and typically seen in trusses and arches; resembles a hinge mechanism.
