EXISTING BUILDING EARTHQUAKE STRENGTHENING METHOD AND EARTHQUAKE STRENGTHENING FRAME
PROBLEM TO BE SOLVED: To provide an earthquake strengthening method and earthquake strengthening frame capable of suppressing bending deformation to the outside of a reinforcement column facing an existing column, and maintaining a reinforcement effect, when shear fracture occurs and a displacement in the axial direction is generated in the existing column in a disaster caused by an earthquake.SOLUTION: When an earthquake strengthening frame 20 is constructed to be adjacent to a structure plane of an existing building 10, a height of a reinforcement column 22A is set to be greater than a height of a beam-column connection 28 that is an upper part of an existing column 12 of the first floor. A place of the reinforcement column 22A facing the beam-column connection 28 of the existing column 12 of the first floor is coupled to the beam-column connection 28, and an upper end of the reinforcement column 22A is bonded to a place of the existing column 12 positioned at an upper side from the beam-column connection 28 with mortar M to be immovable in a direction approaching to the place, so that bending deformation to the outside of the reinforcement column 22A is suppressed when shear fracture of the existing column 12 of the first floor occurs and a displacement in the axial direction is generated.
【課題】地震による被災で、既存の柱がせん断破壊を起こし軸方向に変位を生じた場合、この柱に対向する補強柱の外側への曲げ変形を抑制し、補強効果を維持できる耐震補強工法および耐震補強フレームを提供する。【解決手段】耐震補強フレーム２０を既存建物１０の構面に隣接させて構築するに際して、補強柱２２Ａの高さを、１階の既存柱１２の上部をなす柱梁接合部２８の高さよりも大きい寸法に設定する。１階の既存柱１２の柱梁接合部２８に対向する補強柱２２Ａの箇所を、柱梁接合部２８に連結するとともに、補強柱２２Ａの上端を柱梁接合部２８よりも上方に位置する既存柱１２の箇所に、該箇所へ近づく方向へ移動不能にモルタルＭで接合し、１階の既存柱１２がせん断破壊を起こして軸方向に変位した際の補強柱２２Ａの外側への曲げ変形を抑制する。【選択図】図３
