Double-rigidity buckling restrained damper
The invention discloses a double-rigidity buckling restrained damper. The double-rigidity buckling restrained damper comprises an inner core, an outer sleeve, a first bolt set and a second bolt set, wherein the inner core is formed by processing a round bar and comprises a left connecting end, a left transition section, a large yield section, an elastic section A, a small yield section, an elastic section B, a right transition section and a right connecting end, the large yield section and the small yield section are formed by cutting the round bar, the rest parts have the same diameter as the round bar, the elastic section A and the elastic section B are provided with circular holes A and circular holes B at equal intervals, circular holes C and long round holes are formed in the outer sleeve, the centers of the circular holes C are aligned with the centers of the circular holes A in the elastic section A, the centers of the long round holes are aligned with the centers of the circular holes B in the elastic section B, all the holes are connected through bolts, and the large yield section, the elastic section A, the small yield section and the elastic section B are located in the outer sleeve, so that buckling of the large yield section and the small yield section can be effectively restrained by the outer sleeve. When the double-rigidity buckling restrained damper is subjected to external force, the two yield sections yield successively, and secondary rigidity is achieved.
本发明公开了一种双刚度屈曲约束阻尼器，包括内核，外套管，第一螺栓组和第二螺栓组。内核由圆棒加工而成，包含左连接端，左过渡段，大屈服段，弹性段A，小屈服段，弹性段B，右过渡段，右连接端。大屈服段与小屈服段经圆棒切削形成，其余部分和圆棒直径相同。其中，弹性段A和弹性段B等间距开有圆孔A及圆孔B。外套管上开有圆孔C及长圆孔，其中，圆孔C与弹性段A上的圆孔A的中心对齐，长圆孔与弹性段B上的圆孔B中心对齐，各开孔处采用螺栓连接。大屈服段，弹性段A，小屈服段，弹性段B处于外套管之内，使得大、小屈服段的屈曲能得到外套管的有效约束。此双刚度屈曲约束阻尼器受到外力作用时两屈服段先后发生屈服，实现了二次刚度。
