A method of calculating the effects of edge-stiffening beams on bridge structures is presented which is used in conjunction with the normal load distribution theories. The theoretical analysis is given in detail elsewhere so only the governing equations for the various effects are given.nThe method presented is only applicable where the effective depth of the bridge is constant between the stiffening beams. Where the effective stiffness is considerably reduced at the footpaths or the structural connexion between the parapet beams and the roadway is poor, the modifying effects of the parapet beams will be much less than those given in the paper and can be ignored.
