Bolted Stiffened and Unstiffened End Plate Connections
End-plate connections consist of welding the beam to an end-plate and bolting the end-plate to a column flange.
If there is no axial load on the connection, total tensile and compressive forces are equal and opposite in both flanges, so that total force creates a force pair. It is accepted that the center of rotation is in the center of the compression flange.
