ABSTRACT:
A longitudinally extending beam having a concrete upper flange, a web rigidly extending transversely downward from the upper flange along its length, and an arched portion extending between the spaced apart leg portions on the web. A rigid reinforcement member external to the beam spans the arched portion between the leg portions. Means are associated with each leg portion for connecting one end of the reinforcement member to the other whereby when there is transverse load on the girder, the reinforcement member is stressed longitudinally. When a transverse load is applied to the beam, the reinforcement member cooperates with developing an eccentrically compressive force reducing the bending moment on the arched beam.
