If N is the number of rivets in the joint, the strength of a riveted joint against shearing of rivets, is given by
If P is the allowable bending stress in a slab, whose greater and lesser projections from the column faces, are A and B, the thickness (t) of the slab base, is (where w is the intensity of earth pressure.)
The economical depth d of a web plate in which allowable bearing stress is f_{b}, and the maximum bending moment is M, as suggested by Rawater and Clark, is
If R is the reaction on the bearing plate, the minimum moment of. inertia of the bearing stiffener provided at the support of a plate girder of overall depth D, the maximum thickness of the compression flange T, carrying total load W, is
