Double-step concrete-filled steel tube buckling restrained brace
The invention provides a double-step concrete filled steel tube buckling restrained brace which comprises a first core steel plate, a second core steel plate and a restrained steel tube, a strip-shaped bolt hole is formed in one end of the first core steel plate, and positioning bolt holes are formed in the other end of the first core steel plate and the two ends of the second core steel plate. The two ends of the second core steel plate are connected with the two ends of the first core steel plate through positioning bolts respectively, a plurality of core through holes are evenly and symmetrically formed in the middle of the first core steel plate and the middle of the second core steel plate in the length direction, and the constraint steel pipe is fixed outside the first core steel plate and the second core steel plate. The energy-dissipation steel plate is simple in structure, high in energy-dissipation efficiency, rigidity and bearing capacity, only the first core steel plate deforms to dissipate energy under small deformation, the first core steel plate and the second core steel plate work cooperatively to dissipate energy under large deformation, the mechanical property and the energy-dissipation performance are further improved, the anti-seismic property of the structure can be effectively improved, and the seismic response of the structure is reduced.
本发明提供了一种双阶钢管混凝土屈曲约束支撑，包括核心钢板一、核心钢板二和约束钢管，核心钢板一的一端设有条形螺栓孔，核心钢板一的另一端以及核心钢板二的两端均设有定位螺栓孔，核心钢板二的两端分别与核心钢板一的两端通过定位螺栓连接，核心钢板一和核心钢板二的中部沿长度方向均匀对称设置有多个核心通孔，约束钢管固定在核心钢板一和核心钢板二的外部。本发明构造简单、耗能效率高、刚度及承载力高，在小变形下，仅有核心钢板一变形耗能，在大变形下，核心钢板一与核心钢板二协同工作耗能，力学性能与耗能性能进一步提升，能有效提高结构抗震性能，减小结构地震响应。
