Abstract:
1. A floor structure comprising a plurality of structural metal components that each have: a plate-shaped supporting portion that is laid either perpendicular or oblique to an installation surface; a plate-shaped top flange that extends from a top end portion of the supporting portion in parallel with the installation surface; a plate-shaped bottom flange that extends from a bottom end portion of the supporting portion in parallel with the installation surface and in the opposite direction from the top flange, wherein the structural metal components are laid on a flat surface in parallel with each other such that the top flange of one of the mutually adjacent structural metal components covers the bottom flange of the other of the mutually adjacent structural metal material, and a flange width L of the top flange or the bottom flange and a plate thickness t of the top flange or the bottom flange satisfy Formula L≦1.95 E where E is Young's modulus of the structural metal component.
