Earthquake damage repairable deformation reset fabricated steel structure column foot
The invention relates to a civil engineering assembly type structure node technology, in particular to an earthquake damage repairable deformation reset assembly type steel structure column foot which comprises a prefabricated column and a steel foundation, a steel groove is formed in the steel foundation, and connecting side plates with concave parts are arranged on the front side and the rear side of the steel groove correspondingly. Replaceable multilateral rotating energy consumption connecting pieces are installed in the concave portions of the connecting side plates, polygonal side plates fixedly connected with the lower ends of the prefabricated columns are connected to the replaceable multilateral rotating energy consumption connecting pieces, and connecting steel plates hinged to the steel grooves are arranged at the lower ends of the prefabricated columns. And reset devices are arranged between the periphery of the steel foundation and the lower ends of the prefabricated columns. According to the steel structure column base, the rigidity of the connecting piece is weakened through the holes, plastic hinge outward movement is achieved, the deformation capacity of the joint is improved, and the anti-seismic performance of the column base joint is effectively improved.
本发明涉及土木工程装配式结构节点技术，尤其涉及一种震损可修复的变形复位装配式钢结构柱脚，包括预制柱和钢质基础，所述钢质基础上设置有钢槽，位于钢槽的前后侧分别设置有具有凹部的连接侧板，所述连接侧板的凹部内安装有可更换多边旋转耗能连接件，所述可更换多边旋转耗能连接件上连接有与预制柱下端固定连接的多边形侧板，所述预制柱的下端设置有与钢槽相铰接的连接钢板，位于钢质基础的四周与预制柱的下端之间设置有复位装置。该钢结构柱脚通过开孔削弱连接件刚度,实现塑性铰外移,提高节点的变形能力,有效的改善了柱脚节点的抗震性能。
