Multi-order buckling restrained brace
The invention relates to a multi-stage buckling restrained brace which comprises a restraining component, a first-stage core material, stiffening rib plates arranged at the two ends of the first-stage core material and a plurality of second-stage core materials connected with the first-stage core material through limiting devices. The limiting device comprises a limiting stopper and a limiting groove, the limiting stopper is fixedly connected with the first-stage core material and the stiffening rib plate, the limiting groove is formed in the limiting stopper, a limiting block capable of sliding in the limiting groove is arranged at the end of the second-stage core material, and the second-stage core material is stretched or compressed after the limiting block abuts against the end of the limiting groove. By means of innovative design, the limiting stoppers, the stiffening rib plates and the ends of the first-stage core materials form a whole with large rigidity, when the second-stage core materials are pulled or pressed, the bearing capacity of the second-stage core materials is directly transmitted to a building through the whole, and the structure is balanced in stress, reasonable, high in space utilization rate and capable of being used for building construction. Multi-stage yield energy consumption can be perfectly achieved, and the requirements of wind vibration, small earthquakes and medium and large earthquakes for the performance of the damper are met.
本发明涉及一种多阶屈曲约束支撑，包括约束构件、第一级芯材、设置在第一级芯材两端部的加劲肋板及分别通过限位装置与第一级芯材相连的多个第二级芯材，限位装置包括分别与第一级芯材和加劲肋板固定连接的限位器及设置在限位器上的限位槽，第二级芯材的端部设有能够在限位槽内滑动的限位块，当限位块与限位槽的端部相抵触后将对第二级芯材进行拉伸或压缩。本发明通过创新设计，使得限位器、加劲肋板及第一级芯材的端头构成一个刚度较大的整体，第二级芯材受拉或受压时，第二级芯材的承载力通过该整体直接传递到建筑物，该结构受力平衡、结构合理、空间利用率高，可完美地实现多阶屈服耗能，兼顾了风振、小震和中大震对阻尼器性能的要求。
