An end plate connection consists solely of a vertical plate shop-welded to the end of the web transverse to the axis of the beam with fillet welds on each side of the web.
The field connection is made by bolting the end plate to the flange or web of the supporting member.
The eight bolt stiffened (8ES) EEP connection is one of the prequalified moment connections in the AISC 358 standard for special moment frames (SMFs) in seismic regions. In this connection, a stiffener plate is welded between the end plate and the beam flanges to strengthen the extended portion of the end plate.
Moment connections are designed to transfer bending moments, shear forces and normal forces.
The design strength and stiffness of a moment connection are defined in relation to the strength and stiffness of the connected members.
