Self-resetting assembly type concrete multi-mode energy consumption lower column box type connecting structure
The invention relates to a self-resetting assembly type concrete multi-mode energy consumption lower column box type connecting structure which comprises a prefabricated reinforced concrete lower column, a prefabricated reinforced concrete upper column, a plurality of lower side steel boxes, a plurality of upper side connecting pieces and a plurality of energy consumption plate assemblies, and the lower side steel boxes are correspondingly arranged at the corners of the upper end of the prefabricated reinforced concrete lower column; the multiple upper side connecting pieces are correspondingly arranged at the corners of the lower ends of the prefabricated reinforced concrete upper columns. The lower side steel box and the upper side connecting piece are correspondingly and fixedly connected, so that the prefabricated reinforced concrete lower column is connected with the prefabricated reinforced concrete upper column; the multiple energy consumption plate assemblies are located between every two adjacent lower side steel boxes, the lower portions of the energy consumption plate assemblies are fixedly connected with the prefabricated reinforced concrete lower column, and the upper portions of the energy consumption plate assemblies are fixedly connected with the prefabricated reinforced concrete upper column. Friction energy consumption in a small displacement mode and buckling energy consumption in a large displacement mode can be achieved, the problems that an existing energy consumption mode is single and energy consumption is insufficient are solved, and the anti-seismic property of the structure is improved.
本发明涉及一种自复位装配式混凝土多模态耗能下柱柱盒式连接结构，包括：预制钢筋混凝土下柱、预制钢筋混凝土上柱、多个下侧钢盒、多个上侧连接件和多个耗能板组件，多个下侧钢盒对应设置在预制钢筋混凝土下柱上端的角部；多个上侧连接件对应设置在预制钢筋混凝土上柱下端的角部；下侧钢盒和上侧连接件对应固定连接，实现预制钢筋混凝土下柱与预制钢筋混凝土上柱的连接；多个耗能板组件分别位于相邻两个下侧钢盒之间，耗能板组件的下部与预制钢筋混凝土下柱固定连接，上部与预制钢筋混凝土上柱固定连接。本发明可以实现在小位移模态下的摩擦耗能和大位移模态下的屈曲耗能，克服了现有耗能形式单一及耗能不足的问题，提高结构的抗震性能。
