PROBLEM TO BE SOLVED: To heighten the yield strength of a foundation structure without the re-construction of an underground beam. SOLUTION: In a lower structure 11 of an elevated bridge as this earthquake-proof reinforcement structure, a rigid frame 3 of reinforced concrete formed of columns 1, 1 and a beam 2 stretched between column capitals thereof is supported by piles 12, 12, and the columns 1, 1 are erected on footings 13, 13 installed on pile heads of existing piles. In the lower structure 11 of the elevated bridge, a new pile is provided as a pile 14 for reinforcing in a position separate from the existing piles 12, 12, and a footing 15 provided on the pile head of the pile for reinforcing and vicinities of both ends of the beam 2 are connected to each other through braces 16, 16.
