PROBLEM TO BE SOLVED: To provide a floor structure capable of increasing the degree of freedom of design.SOLUTION: A floor part Y of a building is provided with a rigid floor part 1 that is made of an ALC plate 11 placed on an upper part of a beam 4 and that resists in-plane deformation, and a rigidity strength addition element 2 that is attached to the beam 4 and that resists the in-plane deformation. The rigid floor part 1 and the rigidity strength addition element 2 are provided in such a manner as to be flush with each other. Thus, strengh can be increased while torsion of the beam is suppressed, and the degree of freedom of design can be increased. |
