| 摘要 |
A steel primary framing member, or truss, and concrete floor structure in which the top chord of the truss, regardless of cross-sectional configuration, is totally or at least partially embedded in the concrete to cause the concrete floor and steel truss to function together structurally as a composite system. The upper chord of the truss 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.
