Abstract: At VTT Building and Transport, Finland, the composite action between the concrete part and steel sheet of a composite slab with unbonded tendons was investigated by fifteen column tests simulating a load-balanced state. The results from the column tests showed that the transfer lengths were between 350 and 400 mm. They were in agreement with the previous results that the length of an anchorage zone is between the slab thickness (presented for a solid concrete slab) and two times the column side (as for composite columns). The tests showed also that the location of anchors influences on the transfer length of the compressive force to the sheet and on the resistance of the concrete end block.
