Double-stage yielding buckling restrained brace
The buckling restrained brace comprises a sealing barrel, filler and an energy consumption core material, the two ends of the energy consumption core material extend out of sealing plates at the two ends of the sealing barrel, the two outer ends of the energy consumption core material can slide relative to via holes of the sealing plates, an inner cavity of the sealing barrel is filled with the filler, and the filler is arranged in the inner cavity of the sealing barrel. The energy consumption core material comprises a first core material and a second core material assembly, the first core material and the second core material assembly are arranged side by side, the two outer ends of the first core material and the second core material assembly are fixedly connected, the second core material assembly comprises two second core materials, and the first core material and the second core material assembly are fixedly connected. The inner ends, located in the sealing cylinder, of the two second core materials are connected through a limiting device, and the two second core materials slide relatively within a preset stroke. According to the double-stage yielding buckling restrained brace, through the energy consumption core materials arranged in parallel, the energy consumption and seismic resistance effects can be achieved in small earthquakes and large earthquakes correspondingly.
本发明公开了一种双阶段屈服的屈曲约束支撑，包括封筒、填料和耗能芯材，所述耗能芯材的两端部伸出所述封筒两端的封板，所述耗能芯材的两个外端部与所述封板的过孔可相对滑动，所述填料填充在所述封筒内腔中，所述耗能芯材包括第一芯材和第二芯材组件，所述第一芯材和所述第二芯材组件并列设置，所述第一芯材和所述第二芯材组件两个外端部固定连接，所述第二芯材组件包括两个第二芯材，两个所述第二芯材位于所述封筒内部的内端部通过限位装置连接，两个所述第二芯材在预定行程内相对滑动。本发明双阶段屈服的屈曲约束支撑，通过并列设置的耗能芯材，能够分别在小震和大震中起到耗能抗震作用。
