PROBLEM TO BE SOLVED: To provide a reinforcement structure of a steel material having an H-shaped cross section and the reinforcement method wherein the steel material having the H-shaped cross section and a reinforcing member can securely and firmly be unified without welding. SOLUTION: An adhesive layer 7 is provided at least on an inside surface 5 a flange of the steel material 1 having the H-shaped cross section while each concave groove 4 surrounded by the inside surface 5 the flange and a web side face 6 is hardened with concrete-based material 8 placed into, so that the hardened concrete-based material 8 and the steel material 1 having the H-shaped cross section are unified via the adhesive layer 7. Also, the adhesive layer 7 is provided in each inside surface 5 of the flange and each web side face 6 connecting thereto. Moreover, end parts in the width direction of a net-like fiber sheet 9 or a net-like fiber cylindrical body 12 is attached and fixed to the inside surface 5 of the flanges facing to each other while the net-like fiber sheet 9 or the net-like fiber cylindrical body 12 is embedded into the concrete-based material 8. After the net-like fiber sheet 9 is adhered to the steel material 1 having the H-shaped cross section, the concrete-based material 8 is placed. COPYRIGHT: (C)2008,JPO&INPIT
