Forces Acting on a Riveted Joint:

The forces acting onto a rivet or riveted joint might be any one of the following or their combination:

Direct Shear

This is caused through a direct tensile or compressive force in the connecting members acting in line along with the rivet or rivets, and lying in the plane of the holes.

Eccentric Shear

It acts while the line of action of the direct force does not pass through the centre of the single rivet hole (or through the CG of the group of holes, when there are more than one rivet). Here, a direct shear exists along with a twisting moment.

Direct Tension/Compression

This generates a tension or compression in the rivet shank.

Bending Moment

This generates a direct tension in some rivets and compression on others placed on opposite sides of the neutral axis.
