Fabricated replaceable two-stage buckling-restrained energy dissipation supporting component
The invention discloses a fabricated replaceable two-stage buckling-restrained energy dissipation supporting component. The fabricated replaceable two-stage buckling-restrained energy dissipation supporting component comprises a two-stage buckling-restrained energy dissipation structure; the first-stage buckling-restrained energy dissipation structure comprises an inner square steel tube, a plurality of first-stage oval steel tubes and a core material steel plate; the second-stage buckling-restrained energy dissipation structure comprises an outer square steel tube, a plurality of second-stageoval steel tubes and a piston steel tube; and the inner square steel tube is sleeved with the outer square steel tube, the inner square steel tube divides the interior of the outer square steel tubeinto an upper cavity and a lower cavity, the second-stage oval steel tubes are mounted in the upper cavity and the lower cavity correspondingly, and fixing holes are formed in the sides, fixedly connected with the outer square steel tube, of the second-stage oval steel tubes. Good hysteretic energy dissipation performance of steel due to bending and pulling is reasonably utilized, the effect of two times of energy dissipation is achieved, the effect of a damper can be achieved twice, and the defect that the rigidity is reduced too fast in the later period of one-time buckling energy dissipation can be effectively overcome through superposition of the rigidity obtained after two times of buckling.
本发明公开了一种装配式可更换的两级防屈曲耗能支撑构件，包括两级防屈曲耗能结构；第一级防屈曲耗能结构包括内方钢管、多个第一级椭圆形钢管、芯材钢板；第二级防屈曲耗能结构包括外方钢管、多个第二级椭圆形钢管、活塞钢管；外方钢管套在内方钢管外部，内方钢管将外方钢管内部分隔为上下两个空腔，上下两个空腔内均安装第二级椭圆形钢管，第二级椭圆形钢管与外方钢管相固连的一侧开设固定孔。合理地利用钢材因弯曲而受拉的良好滞回耗能性能既达到两次耗能的效果又可以起到两次阻尼器的作用，还可以通过这种两次屈曲后刚度的叠加有效地解决一次屈曲耗能后期刚度下降过快的缺陷。
