ABSTRACT:
An enhancing mechanism to be placed primarily below the neutral axis of a girder is presented. The movement and deflection of the girder causes the enhancing mechanism to alter the bending moment distribution of the girder. The mechanism is configured so that when combined with the girder, the overall dimensions of the combined system is not much bigger than the dimensions of the girder alone. A tension member may be incorporated into the lower boundary of the enhancing mechanism, and connections are used to attach the mechanism to the girder below the neutral axis. The girder and the enhancing mechanism may be made of the same material or different materials. The compression forces developed in the long diagonal members of the enhancing mechanism become a reaction at the girder end points. A direct connection of the long diagonal members to support points load shear directly to the end supports.
