JUNCTION STRUCTURE FOR REINFORCED CONCRETE STRUCTURE, AND REINFORCED CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a reinforced concrete structure that has a member and a fixing part connected and joined by a main reinforcing bar, the reinforced concrete structure eliminating a need on a splice bar or a joint part reinforcing bar, therefore not widening the member, at the same time mitigating a damage to a part other than a connection boundary at a time of a large earthquake, preventing decline in bending strength of a beam itself, mitigating cracking and collapsing of concrete, and offering high energy absorption capacity and significant vibration control effect.SOLUTION: A junction structure between a reinforced concrete member 2 and a fixing part 1 of the reinforced concrete structure includes a reduced cross-section part 13 over a prescribed length of a main reinforcement 10 that connects the reinforced concrete member and the fixing part, the reduced cross-section part having a cross-section area smaller than the cross-section area at both ends of the main reinforcement. Either or both ends of the reduced cross-section part is positioned on or close to a boundary A between the reinforced concrete member and the fixing part, or the boundary A is located within a range of the reduced cross-section part. An opening is formed at the boundary, as the reduced cross-section area of the main reinforcement yields with priority compared to other parts, at a time of earthquake.SELECTED DRAWING: Figure 3
【課題】鉄筋コンクリート構造物の部材と固定部とを主筋により連結し接合する場合、添え筋や接合部筋の必要がなく部材幅が増えずに、大地震時の接合境界以外の部分における破損の軽減、梁自体の曲げ耐力の低下防止、および、コンクリートのひび割れや圧壊等の破損を軽減し、エネルギー吸収能力が大きく制振効果の高い鉄筋コンクリート構造物を提供する。【解決手段】この鉄筋コンクリート構造物における鉄筋コンクリート部材２と固定部１との接合構造は、鉄筋コンクリート部材と固定部とを連結する主筋１０の一定長さ部分の断面をその主筋の両端部よりも縮小した断面縮小部分１３を有し、断面縮小部分の両端のいずれか一方が鉄筋コンクリート部材と固定部との境界Ａもしくは境界近傍に位置するか、または、断面縮小部分の範囲内に境界Ａが位置し、地震時において主筋の断面縮小部分が他部分よりも優先的に降伏することで境界において開きが形成される。【選択図】図３
