A structural member of inadequate capacity for its load or span that is augmented by one or two steel bars anchored to each bearing end at or above the centroid of the girder to assume the tension forces. The bar(s) runs down and below the girder and stand off the girder on one or more struts anchored to the girder at its bottom surface. The struts are sized to accept the compressive forces imposed without bending. The load limit to this member is the crippling capacity (horizontal failure) of the girder.[1]
