摘要： A fastening section structure having a plurality of concentric circle-shaped rib walls (16, 17, 18) around a fastening section (14) of a member (11) having the fastening section (14). The fastening section structure has a bearing strength in at least the second-layer rib wall (17) that is lower than the bearing strength in the innermost-layer rib wall (16) closest to a fastening member (15). Both reinforcement of the fastening section (14) and smooth energy absorption of an external load as a result of progressive failure can be achieved by: giving a specific relationship between the bearing strengths of the concentric circle-shaped rib walls (16, 17); enhancing the strength and rigidity of the fastening section (14); and enabling progressive failure to start from a site furthest away from the fastening section (14).

摘要： Provided is a reinforcement structure for a structural body having a plurality of fastening sections for fixing a structural body main body, wherein a reinforcement body, which is provided with: reinforcement sections which are provided around at least a part of the fastening sections; and connection sections which connect the reinforcement sections to each other, and which is formed separately from the structural body main body with either a material same as that of the structural body main body or a material having a higher elastic modulus or strength than that of the structural body main body, is attached to the structural body main body. The fastening sections themselves of the structural body main body and the portions therearound can be reinforced easily and effectively only by attaching the reinforcement body later without changing the basic structure such as a rib structure of the structural body main body.
