The invention discloses a self-resetting steel frame lateral force resistance system. The system comprises foundations, steel columns, beams, a cantilever wall and dampers, wherein a foundation beam is horizontally fixed between the foundations; the steel columns are vertically arranged on the tops of the foundations, and the bottom ends of the steel columns are connected to the foundations to form a self-resetting column foot structure; the beams are arranged horizontally, and the ends are connected to the side walls of the steel columns; the steel columns and the beams connected on both sides form a self-resetting node structure; the cantilever wall is fixed between the foundations and the adjacent beams above or between two adjacent beams arranged up and down; the middle part of the cantilever wall forms a fracture; and the dampers are fixedly connected to the upper and lower sections of the fracture. By using the self-resetting steel frame lateral force resistance system provided by the invention, the earthquake is resisted by relying on the elastic deformation of the structure when the earthquake is frequently encountered; when the earthquake is rarely encountered, the structural nodes are opened, the self-resetting structure and the dampers make plastic deformation to dissipate the seismic energy to jointly ensure that the nodes and the column feet have good self-resetting performance, thereby realizing the side force resistance, energy consumption and self-resetting function of the whole system.
本发明公开了一种自复位钢框架抗侧力体系，包括基础、钢柱、横梁、悬臂墙和阻尼器；基础之间水平固定有基础梁；钢柱竖直布置在基础的顶面，且钢柱的底端与基础连接形成自复位柱脚结构；横梁水平布置，且端头与钢柱的侧壁连接；钢柱与其两侧连接的横梁形成自复位节点结构；悬臂墙固定在基础梁和上方相邻的横梁之间，或者固定在上下布置的两根相邻的横梁之间；悬臂墙的中部形成断口；阻尼器分别与断口的上下断面固定连接。本发明在常遇地震作用时，依靠结构的弹性变形抵抗地震作用；罕遇地震作用时，结构结点张开，自复位结构与阻尼器塑性变形耗散地震能量，共同保证节点和柱脚具有良好的自复位性能，实现整个体系的抗侧力、耗能与自复位功能。
