Large-span swing self-resetting structure
The invention discloses a large-span swing self-resetting structure. The large-span swing self-resetting structure comprises a concrete foundation, a plurality of bearing columns, a truss roof, a column foot joint structure and a beam end joint structure, wherein the bearing columns and the concrete foundation are vertically arranged, and the truss roof is horizontally arranged at the top ends of the bearing columns; the concrete foundation is provided with limiting grooves for installing the bearing columns, and the positions between the limiting grooves and the bearing columns are filled with column foot flexible cushion layers used for wrapping the bottom ends of the bearing columns; the column foot joint structure comprises column foot cantilever plates, anchor rods and column foot disc spring sets; the column foot cantilever plates are connected to the side wall faces, close to the bottoms, of the bearing columns; a plurality of anchor rods penetrate the column foot cantilever plates to be fixedly connected with the concrete foundation; and the column foot disc spring sets are connected to the anchor rods on the sides, away from the concrete foundation, of the column foot cantilever plates in a sleeving manner. Thus, swing can be conducted during strong earthquakes, forming of plastic hinges at column foot joints is avoided, the structural stability is high, the self-resetting capability is high, the structural damage is small under the strong earthquakes, and the structural residual strain is small after the earthquakes.
本发明公开了一种大跨摇摆自复位结构，包括混凝土基础、若干根与混凝土基础竖直布置的承重柱、水平布置于承重柱顶端的桁架屋盖、柱脚节点结构以及梁端节点结构；混凝土基础上设有安装承重柱的限位凹槽，限位凹槽与承重柱之间填充用于包裹承重柱的底端的柱脚柔性垫层；柱脚节点结构包括柱脚悬挑板、锚杆以及柱脚碟形弹簧组，柱脚悬挑板连接于承重柱靠近底部的侧壁面，若干根锚杆穿过柱脚悬挑板与混凝土基础固定连接，柱脚碟形弹簧组套接于柱脚悬挑板远离混凝土基础一侧的锚杆上。因此在发生强震时可进行摇摆，避免了柱脚节点处塑性铰的形成，结构稳定性强、自复位能力强，在强震下结构损伤小且震后结构残余应变小。
