COMPOSITE STRUCTURAL MEMBER AND SKELETON STRUCTURE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a composite structural member suitable as a megastructure constituent member by completely integrating a steel beam and a slab, and skeleton structure using it. SOLUTION: A beam 1 is integrated with a slab 2 formed of cast-in-place concrete on the upper face, to constitute a composite beam. The beam 1 is composed of a structural member 5 comprising a structural member body 3 extending in one direction and a plate-like reinforcing part 4 integrally formed along the structural member body 3. The reinforcing part 4 and protrusions (recesses) 6 formed on the upper face are formed of steel fiber reinforced super- high strength mortar/concrete such as compact-reinforced compound material.
