Double-insurance collaborative composite energy consumption self-resetting assembly type steel structure column foot connecting joint
The invention provides a double-insurance collaborative composite energy consumption self-resetting assembly type steel structure column foot connecting joint which comprises an I-shaped/H-shaped steel column, a double-insurance collaborative composite energy consumption self-resetting assembly type steel structure and a double-insurance collaborative composite energy consumption self-resetting assembly type steel The ground beam is I-shaped/H-shaped, and the steel column is arranged on the ground beam and fixedly connected with the ground beam; the two sets of bending-shearing composite energy dissipation damping devices are oppositely connected to the two sides of a web plate of the steel column through bolts at the joint of the steel column and the ground beam, and meanwhile are connected with an upper flange of the ground beam through bolts; the two sets of tension-shear composite energy dissipation damping devices are oppositely connected to the outer surfaces of the two flanges of the steel column through bolts at the joint of the steel column and the ground beam and are connected with the upper flange of the ground beam through bolts; the two sets of self-resetting devices comprise prestressed cables and prestressed tools, the prestressed tools are oppositely fixed to the ground beam and the two sides of the web of the steel column, and the two ends of the prestressed cables are anchored to the prestressed tools. Through reasonable design, the column base connecting joint keeps elasticity under small and medium earthquakes, and can be continuously used without repairing; the main body structure keeps elastic under large earthquakes and super-large earthquakes, and continuity of building structure functions is achieved by replacing the energy dissipation assembly.
本发明提出一种双保险协同复合耗能的自复位装配式钢结构柱脚连接节点，包括：钢柱，为工字型/H型；地梁，为工字型/H型，所述钢柱设置在地梁上并与地梁连接固定；两套弯剪复合耗能阻尼装置，在所述钢柱与地梁的连接处通过螺栓对置地连接于钢柱的腹板两侧，同时与所述地梁的上翼缘通过螺栓连接；两套拉剪复合耗能阻尼装置，在所述钢柱与地梁的连接处通过螺栓对置地连接于所述钢柱的两翼缘外表面，同时与所述地梁的上翼缘通过螺栓连接；两套自复位装置，包括预应力索和预应力工装，所述预应力工装对置地固定于所述地梁和所述钢柱的腹板两侧，所述预应力索两端锚固于所述预应力工装。本发明通过合理设计，柱脚连接节点在小、中震下保持弹性，无需修缮即可继续使用；在大震和超大震下主体结构保持弹性，通过更换耗能组件实现建筑结构功能的连续。
