PROBLEM TO BE SOLVED: To provide a floor slab structure provided with a concrete floor slab on a beam and capable of preventing unreasonable force from being applied on a column. SOLUTION: In this floor slab structure provided with the concrete floor slab 6 constituted by placing cast-in-place concrete on the beam 1 and connecting the steel column 5 with the steel beam 1, the beam 1 has upper and lower flange parts 2, 3 and a web part 4 for connecting these upper and lower flange parts 2, 3 mutually, a clearance 12 is formed between an end face 6A being an end part of the concrete floor slab 6 and the column 5, and a concrete member 11 being an edging member is provided between the concrete floor slab 6 and the beam 1. Consequently, the steel beam 1 and the concrete floor slab 6 are not integrated so that energy of earthquake and typhoon can be absorbed by plastic deformation of the steel beam 1. Even if the steel beam 1 is deformed, load is not applied on the column 5 from the concrete floor slab 6 by virtue of the clearance 12, and flexural yield strength becomes original strength of the beam 1.
