Self-resetting energy dissipation square column foot
The invention belongs to the technical field of steel structure damping, and particularly relates to a self-resetting energy dissipation square column foot. Comprising square steel columns, a top plate, a bottom plate, stiffening plates, steel strands and mild steel energy dissipation devices. The top plate is vertically and fixedly connected with the square steel column; the stiffening plates are distributed on the periphery of the square steel column; the stiffening plates are connected with the bottom plate through the soft steel energy dissipation devices, and when the soft steel energy dissipation devices are in an unfolded state, movable gaps are reserved between the stiffening plates and the square steel columns and the bottom plate. Prestressed holes are formed in the top plate and the bottom plate and around the square steel column, the prestressed holes in the top plate and the bottom plate are coaxial, a steel strand penetrates through every two coaxially arranged prestressed holes, one end of each steel strand is anchored on the top plate, and the other end of each steel strand is pre-buried in the concrete base; the soft steel energy dissipation devices are additionally arranged on the four sides of the column foot portion of the square steel column respectively, earthquake energy transmitted to the square steel column is dissipated through buckling deformation of the soft steel energy dissipation devices, and therefore the damping effect is achieved.
本发明属于钢结构减震技术领域，具体涉及一种自复位耗能方柱柱脚；包括方型钢柱、顶板、底板、加劲板、钢绞线和软钢耗能装置；顶板与方型钢柱垂直固定连接；加劲板分布在方型钢柱的四周；加劲板与底板之间通过软钢耗能装置连接，软钢耗能装置展开状态下，加劲板和方型钢柱与底板之间预留活动空隙；顶板和底板上在方型钢柱四周开有预应力孔，顶板和底板上的预应力孔同轴，每两个同轴布置的预应力孔内穿有一根钢绞线，钢绞线的一端锚固在顶板上，另一端预埋在混凝土基座中；本发明在方型钢柱的柱脚部位四侧分别加装软钢耗能装置，通过软钢耗能装置屈曲形变耗散传递到方型钢柱上的地震能量，以此起到减震的作用。
