PROBLEM TO BE SOLVED: To provide a reinforcing structure for an existing building that reduces resisting force against floating borne by resisting force providing means, or reduces the number of resisting force providing means, for controlling overturning of a three-dimensional frame.SOLUTION: A reinforcing structure for an existing building includes: a pair of structures 10A, 10B facing each other that are laid out opposite each other; a foundation structure 12 constructed between existing buildings; a pair of three-dimensional frames 14A, 14B constructed along and connected to the existing buildings; a first column part 34 of the three-dimensional frame located close to the existing building and having a lower edge part fixed on the foundation structure; a second column part 36 of the three-dimensional frame located further from the existing building and having a lower edge fixed on the foundation structure; and resisting force providing means 18, 20 having a lower end embedded in a ground 22 underneath the foundation structure and an upper end fixed on the foundation structure, providing resisting force R against floating to the foundation structure and providing larger resisting force against pull-out to the first column part than the second column part.SELECTED DRAWING: Figure 2 |
