1. A structural load bearing assembly comprising:
a structural member;
a serrated horizontal top flange and a serrated vertical top flange connected to the structural member, said serrated horizontal top flange member comprising a first plurality of serrations arranged in a spaced apart manner on the serrated horizontal top flange member and defining a plurality of voids between adjacent serrations of the first plurality of serrations, and said serrated vertical top flange member comprising a second plurality of serrations arranged in a spaced apart manner on the serrated vertical top flange member and defining a plurality of voids between adjacent serrations of the second plurality of serrations, wherein each of the second plurality of serrations comprises a head portion, and a shaft portion, and said plurality of voids each have a shape that is substantially a mirror image of a shape of each of the second plurality of serrations; and
wherein a width of the head portion measured in a direction parallel to a long axis of said structural member is greater than a width of the shaft portion measured in the direction parallel to the long axis of said structural member, and wherein each of said shaft portions have a first substantially linear side perpendicular to the long axis and a second substantially linear side, and each of said head portions have a first substantially linear side perpendicular to the long axis and a second substantially linear side;
a structural medium defining a floor slab disposed at a top portion of said structural member, wherein said structural medium encases the first plurality of serrations of the serrated horizontal top flange and the second plurality of serrations of the serrated vertical top flange to provide a horizontal shear transfer between the floor slab through the first and second plurality of serrations to the serrated horizontal and vertical top flanges to sufficiently develop a composite action between the structural member and slab.
