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.

A concrete fillable steel joist includes a generally U-shaped member and a top chord. The generally U-shaped member has spaced apart webs and a bottom chord. The top chord is operably attached to the U-shaped member. The top chord has a plurality of spaced apart top chord holes. The U-shaped member and the top chord define a volume that is fillable with concrete when opposed ends of the U-shaped member have joist ends operably attached thereto. The joist ends may be a pair of end plates. Alternatively, the joist ends may be structural members. A concrete fillable steel joist system includes a plurality of spaced apart concrete fillable steel joists, and metal decking. The metal decking is operably attached between the spaced apart steel joists. The concrete fillable steel joist and the metal decking are configured to receive concrete.

Improved tub girders and related manufacturing methods are provided, such as for example for use in road construction in connection with concrete bridges. Disclosed improved tub girders may include upper flanges that extending inwardly or outwardly. Disclosed improved tub girders may be provided with camber along the length of the girders. Ends of the disclosed improved tub girders may be provided with diaphragms. Disclosed improved tub girders may include a base section including one more access ports for enabling inspection of the interior of the girders after installation. Disclosed improved tub girders may include a plurality of stud members extending upwardly from upper flanges for engaging with a concrete bridge deck. Disclosed tub girders may be providing with a coating, such as galvanized, aluminized or metalized, to fight corrosion and extend life and limit need for inspection.
