  • Publication number: 20240125138
    Abstract: A steel panel damper is provided for reinforcing a building structure. The steel panel damper is disposed between a first member and an opposite second member arranged in the building structure. The steel panel damper comprises a first elastic segment, a second elastic segment, an energy dissipation segment, a first end plate, and a second end plate. In terms of the cross-sectional area perpendicular to the first direction, the first elastic segment and the second elastic segment are greater than the energy dissipation segment.

  • Publication number: 20120233955
    Abstract: A buckling restrained brace includes an axial member, a plurality of restraining members, and a plurality of securing units. The axial member includes a middle section extending in an axial direction, and a pair of coupling sections extending respectively from opposite ends of the middle section and that are adapted to be coupled fixedly to two connecting plates of a framework of a building, respectively. The restraining members extend in the axial direction, and are disposed around and contact the axial member. Each securing unit secures an adjacent pair of the restraining members together. Each restraining member cooperates with an adjacent one of the restraining members to define an opening therebetween through which a portion of the axial member is exposed for viewing.

  • Publication number: 20110232221
    Abstract: A buckling restrained brace is for connection between two connecting plates of a framework, and includes a restraining unit and an axial member. The axial member includes a middle section surrounded by the restraining unit, two first coupling sections, and two second coupling sections. The first coupling sections are connected respectively and perpendicularly to opposite longitudinal end portions of the middle section. Each first coupling section has a portion exposed from a respective one of longitudinal ends of the restraining unit, and is formed with a first coupling groove for engaging a respective one of the connecting plates. The second coupling sections are connected respectively and perpendicularly to the opposite longitudinal ends of the middle section. Each second coupling section has a portion exposed from a respective one of the longitudinal end portions of the restraining unit, and is formed with a second coupling groove for engaging a respective one of the connecting plates.
