PROBLEM TO BE SOLVED: To provide an impact absorbing device having high material axis direction deformability and energy absorption capacity, to be mainly arranged between a bridge girder edge and a bridge abutment which supports the bridge girder edge.SOLUTION: A joint part 5 and a joint part 6 are installed at both ends in the material axis direction. A deforming core material 7 and a deforming core material 8 are arranged adjacently in the material axis direction along the same material axis line between the joint part 5 and the joint part 6. A plurality of buckling constraint materials 9 are arranged on the outside of the axially perpendicular direction of the deforming core material 7 and the deforming core material 8. The deforming core material 7 is arranged to be elastically plastically deformed with respect to an axial force. The deforming core material 8 is arranged to be displaced in the material axis direction with no resistance in a state in which the connection to the joint part 5 is separated with respect to the axial force.SELECTED DRAWING: Figure 1
【課題】材軸方向の変形能力およびエネルギー吸収能力が高く、主として橋桁の端部と橋桁端部を支える橋台との間に設置される衝撃吸収装置を提供する。【解決手段】材軸方向の両端部に継手部５と継手部６を取り付ける。継手部５と継手部６間の同一材軸線上に変形芯材７と変位芯材８を材軸方向に隣接して配置する。変形芯材７および変位芯材８の軸直角方向の外側に複数の座屈拘束材９を配置する。変形芯材７は軸力に対し弾塑性変形するように配置する。変位芯材８は軸力に対し継手部５との連結が切り離された状態で無抵抗で材軸方向に変位するように配置する。【選択図】図１
