Design of Bolted Beam Connections

Connection may be

1. Simple connection/flexible connection

2. Moment resistant/rigid connection.

1. Flexible Connection Types

(a) Framed connection

(b) Unstiffened seated connection

(c) Stiffened seated connection.

(a) Framed connection If the shear to be transferred is less, the beam may be connected to the main

beam or column using cleat angles only.

(b) Unstif ened seated connection If shear force is larger the depth of cleat angle required for framed

connection may become more than the depth of beam to be connected. In such case seat angle is

connected to column over which beam rests. At top nominal cleat angles are provided.

(c) Stif ened seated connection If the shear to be transferred is still larger seat angles are stiffened

with angles.

2. Rigid/Moment Resistant Connection If moment to be transferred is small clip angle or split beam

connection may be made. If moment to be transferred is large, bracket connection may be used.

Design of Welded Beam Connections

For flexible connection framed connection, unstiffened seated connection or stiffened seated

connections can be used.

For rigid/moment resistant connections, double plated framed connections or double angle framed

connections may be used.
