Abstract
A structural member section comprised of horizontal top and bottom flange elements interconnected by one or more vertical web member. The top flange of the member is serrated such that a series of serrations protrude horizontally in at least one direction from a top of the one or more vertical web member or are cut-out from the flange of a rolled shape. In one embodiment, the serrated top flange and at least a portion of the web member are intended to be encased by a horizontal concrete slab or slab-on-deck assembly. The slab material is capable of encasing all exposed surfaces of and curing around each serration to transfer horizontal shear forces between the serrated top flange and the slab material such that the member and slab behave compositely.
Claims12
A structural member spanning one or more structural supports, the structural member comprising:
- a serrated horizontal top flange member operably coupled to one or more vertical web member, said serrated horizontal top flange member comprising a 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 plurality of serrations;
- wherein each of the plurality of serrations comprises a head portion, and a shaft portion and wherein said serrations are co-planar with said horizontal top flange member, and said plurality of voids each have a shape that is substantially a mirror image of a shape of each of said plurality of serrations;
- 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 and a second substantially linear side, and each of said head portions have a first substantially linear side and a second substantially linear side.
A structural load bearing assembly comprising:
- a structural member having a serrated horizontal top flange, said serrated horizontal top flange member comprising a 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 plurality of serrations;
- wherein each of the plurality of serrations comprises a head portion and a shaft portion, and wherein said shaft portion has a first substantially linear side and a second substantially linear side, and said head portion has a first substantially linear side and a second substantially linear side;
- wherein a width of the head portion measured in a direction parallel to a long axis of said structural member between the first substantially linear side and the second substantially linear side of the head portion is greater than a width of the shaft portion measured in the direction parallel to the long axis of said structural member between the first substantially linear side and the second substantially linear side of the shaft portion, and wherein said serrations are co-planar with said horizontal top flange member;
- and
- a structural medium defining a floor slab disposed above said structural member, wherein said structural medium encases the plurality of serrations of the serrated horizontal top flange to provide a horizontal shear transfer between the floor slab through the serrations to the serrated horizontal top flange to sufficiently develop a composite action between the structural member and slab.
