SQUARE STEEL PIPE COLUMN REINFORCING STRUCTURE
To provide a square steel pipe column reinforcing structure capable of improving the performance of a square steel pipe column with simple structure and weight-suppressed structure.SOLUTION: In a square steel pipe column reinforcing structure 100, by appropriately selecting the size of a reinforcing material according to a square steel pipe column 1 to be reinforced, the local buckling of the square steel pipe column 1 is allowed, but the buckling deformation is moderately restrained so that the decrease in yield strength after the local buckling can be moderated, and the deformation performance can be improved. Further, by limiting the reinforcement to the end part of the square steel pipe column 1 where the local buckling may occur, a significant increase in the number of processes can be avoided. In addition, by attaching a reinforcing member 20 at a predetermined interval from the end surface of the square steel pipe column 1 in the longitudinal direction, it is possible to prevent an excessive increase in the yield strength of the square steel pipe column 1 which may affect the design of a peripheral member.SELECTED DRAWING: Figure 3
【課題】シンプルな構造であり、且つ重量を抑制した構造にて、角形鋼管柱の性能を向上できる角形鋼管柱補強構造を提供する。【解決手段】角形鋼管柱補強構造１００では、補強する角形鋼管柱１に応じた適切な補強材サイズの選定によって、角形鋼管柱１の局部座屈は許容するが当該座屈変形を適度に拘束することで、局部座屈後の耐力低下を緩やかにし、変形性能を向上させることができる。また、角形鋼管柱１の局部座屈が発生しうる端部に補強を限定することで、工数の大幅な増加を避けることができる。また、補強材２０を角形鋼管柱１の長手方向の端面から一定の間隔をあけて取り付けることで、周辺部材の設計への影響を伴うような、角形鋼管柱１の過度な耐力上昇を防ぐことができる。【選択図】図３
