Multi-stage stress anti-collapse buckling restrained brace
The invention discloses a multi-stage stress buckling restrained brace which comprises a buckling-free energy dissipation core, an upper connecting end, a lower connecting end, a standby pull rod system, a standby force transmission restraining outer pipe and an elastic cushion block. The two ends of the buckling-free energy dissipation core are connected with the upper connecting end and the lower connecting end in a welded mode respectively, the standby force transmission restraining outer pipe comprises a pipe body and a reinforcing end, elastic cushion blocks are arranged between the reinforcing end and the upper connecting end and between the reinforcing end and the lower connecting end, and the reinforcing end is connected with the upper connecting end and the lower connecting end through a standby pull rod system. The height of the elastic cushion block is smaller than the value of an inner gap between the reinforcing end and the upper connecting end and the value of an inner gap between the reinforcing end and the lower connecting end, and the length of the standby pull rod system is obviously larger than the distance between the reinforcing end and the outer surface of the upper connecting end and the distance between the reinforcing end and the outer surface of the lower connecting end. After the non-buckling energy dissipation core exceeds a deformation limit value, the rigidity and the bearing capacity of the support can be greatly improved, and the anti-collapse performance of the structure under the action of a strong earthquake is improved.
本发明公开了一种多阶段受力屈曲约束支撑，包括：无屈曲消能核芯、上连接端头、下连接端头、备用拉杆系统、备用传力约束外管、弹性垫块；所述无屈曲消能核芯的两端分别与上连接端头、下连接端头焊接连接，备用传力约束外管包括管身与加强端头，加强端头与上、下连接端头之间有弹性垫块，并通过备用拉杆系统连接，弹性垫块的高度小于加强端头与上、下连接端头之间的内间隙值，备用拉杆系统的长度显著大于加强端头与上、下连接端头外表面距离，本发明实现的有益效果是：该多阶段受力屈曲约束支撑为结构提供了多阶段的抗侧性能，在无屈曲消能核芯超出变形限值后，该支撑的刚度及承载力能够大幅增加，提高结构在强烈地震作用下的抗倒塌性能。
