Experimental 6-in.-deep composite floor units consisting of interlocking flat-bottomed steel-sheet pans with webs projecting into a voided concrete top slab were tested. A short-span shear test and a long-span bending test demonstrated that the units act as composite steal-concrete structures and can be safely designed by conventional methods for one-way bending. Also, a lateral-load-distribution test indicated the two-way bending strength of this floor. A punching test and an erection test demonstrated the durability.
