Steel structure buckling restrained brace
The invention discloses a buckling restrained brace for a steel structure, which belongs to the technical field of building shock absorption and comprises a restrained shell. The self-resetting core plate is located in the constraint shell, penetrates through the two ends of the constraint shell and extends to the outer side of the constraint shell, and slippage displacement is reserved between the self-resetting core plate and the constraint shell, so that relative sliding of the self-resetting core plate and the constraint shell is achieved; the two gusset plates are connected to the two ends of the self-resetting core plate correspondingly, and the other ends of the gusset plates are connected with the steel structures at the corresponding positions. According to the steel structure buckling restrained brace, the slippage displacement is reserved between the self-resetting core plate and the restrained shell, large slippage can be provided during a large earthquake, mutual friction is generated between the self-resetting core plate and the restrained shell for shock absorption, and the steel structure buckling restrained brace has better energy dissipation capacity and fatigue resistance.
本发明公开了一种钢结构屈曲约束支撑，属于建筑减震技术领域，其包括约束外壳；自复位芯板位于约束外壳内，并贯穿约束外壳的两端延伸至约束外壳的外侧，自复位芯板与约束外壳之间预留有滑移位移量，以实现自复位芯板与约束外壳的相对滑动；两个节点板，分别连接于自复位芯板的两端，节点板的另一端与对应位置的钢结构连接。本发明钢结构屈曲约束支撑通过自复位芯板与约束外壳之间留有滑移位移量，可以在大震时，提供较大滑移量，并与约束外壳产生相互摩擦进行减震，具有更加良好的耗能能力和耐疲劳性能。
