Energy dissipation and shock absorption column foot structure
The invention discloses an energy dissipation and shock absorption column foot structure, and relates to the technical field of building anti-seismic structures, the energy dissipation and shock absorption column foot structure comprises a bottom beam, a top beam, a supporting column and unbonded prestressed tendons, and the top end and the bottom end of the supporting column abut against the top beam and the bottom beam respectively; shoulders are arranged at the bottoms of the supporting columns, and energy dissipation mechanisms are evenly arranged at the bottoms of the shoulders; the unbonded prestressed tendons are coaxially arranged in the supporting columns; when the supporting column is subjected to an earthquake load, the action generated by an earthquake is redistributed between the middle column and the side wall with high rigidity, so that the action of the earthquake on the supporting column with low lateral rigidity is reduced, and the internal stress of the supporting column is correspondingly reduced. Meanwhile, the energy dissipation mechanisms arranged on the shoulders can absorb earthquake energy, the supporting columns are delayed to enter the yield state, the unbonded prestressed tendons have the deformation self-recovery capacity, and when the supporting columns incline and deform, resetting of the supporting columns is facilitated.
本发明公开一种耗能减震柱脚结构，涉及建筑抗震结构技术领域，包括底梁、顶梁、支撑柱和无粘结预应力筋，支撑柱的顶端、底端分别与顶梁、底梁抵接；支撑柱的底部设置有台肩，台肩底部均匀设置有耗能机构；无粘结预应力筋同轴设置在支撑柱内；当支撑柱受到地震载荷时，地震产生的作用在中柱和刚度较大的侧墙之间重新分布，使得侧向刚度较小的支撑柱受到地震作用减小，其内部应力也相应减小。同时台肩上设置的耗能机构能够吸收地震能量，延缓支撑柱进入屈服状态，无粘结预应力筋具有形变自恢复能力，当支撑柱产生倾斜变形时有利于支撑柱进行复位。
