<p>A steel primary framing member, or truss (12), and concrete floor structure (54) in which the top chord of the truss (12), regardless of cross-sectional configuration, is totally or at least partially embedded in the concrete to cause the concrete floor (54) and steel truss (12) to function together structurally as a composite system. The upper chord of the truss (12) acts as a continuous or substantially continuous shear connector thus enabling the top chord to perform a multi-purpose function. Additionally, the top chord may be of any configuration and may be either a solid piece or contain perforations.</p> |
