REINFORCEMENT ARRANGEMENT STRUCTURE
To provide a reinforcement arrangement structure capable of enhancing energy absorbing performance in a column beam connection part while enhancing bending proof stress.SOLUTION: A first reinforcement arrangement structure 100 mainly comprises four core reinforcing steel rods 111-114, four core pipes 121-124, and ten core confining steel 131, and is provided along the insides of a column 10 and a beam 20. The core reinforcing steel rods 111-114 extend in parallel from each other along the inside of the column 10 and the beam 20. Core confining steel 151 is attached so as to wind the core steel rods 111-114 located in the column 10 and restrict them. The core pipes 121-124 comprise four cylindrical steel pipes having an inner diameter which is identical or substantially identical to an outer diameter of the core reinforcing steel rods 111-114, for example, an inner diameter of 13 mm. In the inner circumference of the core pipes 121-124, the core reinforcing steel rods 111-114 are inserted from an opening opposing the column 10 so as to freely reciprocate. By the above, concrete is not adhered to the core reinforcing steel rods 111-114, and the core reinforcing steel rods 111-114 are not restricted by the beam 20 longitudinally.SELECTED DRAWING: Figure 1
【課題】曲げ耐力を確保しながら、柱梁接続部におけるエネルギー吸収性能を確保可能な配筋構造を得る。【解決手段】第１の配筋構造１００は、４本のコア鉄筋１１１〜１１４と、４本のコア管１２１〜１２４と、１０本のコア拘束筋１３１とを主に備え、柱１０内から梁２０内に渡って設置される。コア鉄筋１１１〜１１４は、柱１０内部から梁２０に渡って互いに平行に延びる。柱１０内部に位置するコア鉄筋１１１〜１１４を巻回すように柱内拘束筋１５１が取り付けられ、これらを拘束する。コア管１２１〜１２４は、コア鉄筋１１１〜１１４の外径と同じ又は略同じ内径、例えば１３ｍｍの内径を有する円筒型の鋼管４本から成る。コア管１２１〜１２４の内周には、柱１０に対向する開口からコア鉄筋１１１〜１１４が進退自在に挿入される。これにより、コア鉄筋１１１〜１１４にコンクリートが付着せず、コア鉄筋１１１〜１１４は梁２０の長手方向に拘束されない。【選択図】図１
