FITTING STRUCTURE OF ELASTO-PLASTIC DAMPER TO EXISTING STRUCTURAL MEMBER
PROBLEM TO BE SOLVED: To add an elasto-plastic damper to an existing structural member in a state the plastic deformation capacity of the existing structural member functions, which is shear-deformed when the existing structural member receives shear force in an in-plane direction.SOLUTION: Plural reinforcement members 4, 4 are disposed at a certain distance from each other in an axial direction along an existing structural member 3 in a direction perpendicular to a plane on which shear force acts to shear-deform the existing structural member 3. The reinforcement members 4, 4 positioned at both sides in the axial direction are joined to structural members 1 respectively. An elasto-plastic damper 5 having a plastic deformation part 51, which can shear-yield when shear force is applied to an in-plane direction, is disposed between the reinforcement members 4, 4 which are disposed at a certain distance in the axial direction. A part segment 31 of the existing structural member 3 is removed excluding both ends in the axial direction while leaving a part in an H-direction.
【課題】既存構造部材に面内方向のせん断力を受けてせん断変形する弾塑性ダンパーを付加する場合に、既存構造部材の塑性変形能力を発揮し得る状態で、既存構造部材に弾塑性ダンパーを付加する。【解決手段】既存構造部材３をせん断変形させるせん断力の作用面に直交する方向に、既存構造部材３に沿って複数本の補強部材４、４を軸方向に互いに距離を置いて配置し、軸方向の両側に位置する補強部材４、４を各主構造部材１に接合し、軸方向に距離を置いた補強部材４、４間に面内方向のせん断力を負担してせん断降伏し得る塑性変形部５１を有する弾塑性ダンパー５を跨って設置し、既存構造部材３の軸方向の端部を除く一部区間３１を成方向の一部を残して除去する。【選択図】図１
