This type of the slim floor slab consists of newly constructed steel and concrete composite beamconnected together with prefabricated or cast in situ floor slab. The slabs have been supported on lower flanges of the composite beamto provide a flat lower surface of finished floor slab. The studs have been devised as the set of horizontal rebars passing through the perforated webs of the beam and anchored in the circular openings of the hollowcore slabs. Two types of structures, each consisting of composite beam and the prefabricated floor slabs, have been the subject of full scale tests performed in cooperation with ITB strength tests laboratory. Experimental and computational results showed satisfactory consistence. Keywords: composite structures; steel-concrete structures; shear connections; full-scale tests.
