Self-resetting steel column foot
The invention discloses a self-resetting steel column foot. The self-resetting steel column foot comprises a basic part, the steel bottom plate is arranged on the top surface of the basic part; the steel columns are fixed to the steel bottom plate, and the side walls of the bottom ends of the steel columns are provided with radially-protruding energy dissipation steel plates. The anchor rods are divided into two groups and are respectively arranged on the inner side and the outer side of the steel column; the bottom ends of the anchor rods on the inner side of the steel column are fixed into the foundation part, upwards penetrate through the steel bottom plate and are sleeved with disc springs, the bottom ends of the anchor rods on the outer side of the steel column are fixed into the foundation part and upwards penetrate through the steel bottom plate and the energy dissipation steel plate, and the anchor rods on the outer side of the steel column are arranged on the outer side of the steel column in a surrounding mode; the top ends of the anchor rods are all fastened through bolts. According to the self-resetting steel column base, damage to the structure is relieved through bottom lifting after an earthquake, the structure swings under the action of the earthquake, the structure is reset through prestress to form a self-resetting structure, the self-resetting steel column base is high in energy dissipation capacity and has excellent self-resetting capacity, the anti-seismic capacity is improved, overall residual deformation of the structure is small, and damage to structural components is low.
本发明公开了一种自复位钢柱柱脚，包括基础件；钢底板布置在基础件的顶面；钢柱固定在钢底板上，钢柱底端侧壁具有径向凸出的消能钢板；锚杆的数量为多根，且分为两组，并分别布置在钢柱的内侧和外侧；钢柱内侧的锚杆底端固定基础件内部，且向上穿过钢底板，并套设有碟型弹簧，钢柱外侧的锚杆底端固定基础件内部，且向上穿过钢底板和消能钢板，钢柱外侧的多根锚杆环绕布置在钢柱外侧；多根锚杆的顶端均通过螺栓紧固。本发明震后通过底部抬升来减轻结构的破坏，则结构在地震作用下发生摇摆，通过预应力使结构复位形成自复位结构，该自复位钢柱柱脚耗能能力强，且具备优良的自复位能力，提高了抗震能力，结构整体残余变形较小，结构构件的损伤较低。
