Point Loads on Composite Deck-Reinforced Slabs

The behavior of composite deck-reinforced floor systems under concentrated loads is described. Laboratory experiments show that these floor systems may have a considerably larger capacity to support concentrated loads than indicated by existing design techniques. There are two sources of this additional strength. First, continuity of the slab and slip restraint of stud shear connectors increase the shear bond capacity. Further benefit is obtained through the distribution of the load effects over the weak direction of the one way slab. The utilization of these benefits may produce significant economics in the design of floors to resist concentrated loads.
