The research studies experimentally behavior of composite two-way slab that consist of flat steel plate and concrete with screws as shear connectors. The screws differ in length and diameter with distributed of them according to shear stresses [dense distribution nearest from support] and by using the same weight of screws in each slab (819±8) g. Six composite slabs was cast in this work and tested under equivalent uniform distributed repeated load [EUDRL]. The various parameters were investigated in this work including the diameter of screws (6.3, 4.2, 3.5) mm and length of screw (25 and 12.5) mm. The results of the present experimental study demonstrated that the composite slab with diameter of screws (4.2mm) and length (12.5mm) is the best among others composite slab in this work. The strength of the best tested composite slab (using screws of (4.2mm diameter and 12.5mm length) is closed to that of reinforced concrete slab (R/C) with difference about (7.1%). On other hand, the ductility of composite slab is better than of (R/C) slab by about (6.7% to 24.74%).
