ABSTRACT
Gravity composite systems may be broadly classied into composite Šoors and composite columns. Composite Šoor systems typically consist of simply supported steel rolled sections, and occasionally nonprismatic steel sections such as tapered, dapped, or castellated beams including haunch girders, trusses, or stub girders. Invariably, in all cases the steel member is attached to the concrete topping via shear connectors welded to the member through a formed composite metal deck. The entire Šoor system consisting of steel sections, metal deck, and concrete topping responds as a series of Šexural T-beams under gravity loads. Shown in Figure 4.1 are the typical components of composite Šoor used nearly exclusively in steel-framed buildings in North America.
