N2 - In the design of steel structures, composite effects of stud shear connectors are generally measured using ordinary push-out tests. Furthermore, based on those results, the evaluation formulas of the ultimate shear strength are given in design guidelines. However, a concrete slab is subjected to reversed stress during an earthquake, whereas existing tests consider only compressive stresses on concrete. The mechanical behavior in existing structures thereby might be different from that under compressive force alone. This research proposes a component model of a composite beam modeling the stress in actual buildings. Furthermore, cyclic loading tests were conducted on 14 specimens with different specifications of the stud shear connector, concrete, and rebar. The results showed that the ultimate shear strength is considerably lower than that under compressive stress. Consequently, this paper presents equations to assess structural performance precisely considering various influential factors of composite structures.
