BUCKLING RESTRAINING BRACE
To provide a buckling restraining brace which secures absorption performance of vibration energy.SOLUTION: A buckling restraining brace includes a core material having a first portion including a region that is plastically deformed when receiving a compression or tensile load in a material axis direction and second portions provided on both ends of the first portion, and a stiffener surrounding at least the periphery of the first portion, in which the second portion has a bearing force higher than that of the plastically deformed region. In the core material, the first portion and the second portion are formed of different members, and the member forming the second portion has a bearing force higher than that of the member forming the first portion.SELECTED DRAWING: Figure 4
【課題】振動エネルギーの吸収性能が確保された座屈拘束ブレースを提供する。【解決手段】材軸方向に圧縮又は引張の荷重を受けたとき塑性変形する領域を含む第１部分と第１部分の両端に設けられた第２部分とを有する芯材と、少なくとも第１部分の周囲を囲繞する補剛材と、を備え、第２部分は、塑性変形する領域よりも耐力が高い、座屈拘束ブレースが提供される。芯材は、第１部分と第２部分とが異なる部材で形成され、第２部分を形成する部材は、第１分部を形成する部材より耐力が高い。【選択図】図４
