An improved composite concrete and steel construction system for floor framing members using composite action open web steel joist and concrete slab construction, composite beams; unpunched corrugated decking and composite joists at columns only. All beams are composite and all joist ends are composite at the beams. Joists between the columns are standard open web joists. This composite system results in the columns having floor supporting members in both major directions that are composite with the poured in place concrete slab, thus providing superior bracing of the columns and direct duplication of the horizontal forces in the slab to the column through the supporting members. This design utilizes less composite joists, allows greater leeway in the spacing of the composite joist webbing and is economical. The floor slab will still act as a diaphram in both major directions due to the composite beams and the composite joists at the columns acting at right angles to one another.
