Self-resetting swinging lattice type column with replaceable corrugated steel plate damper
The invention belongs to the field of earthquake prevention and disaster reduction of building structures, and discloses a self-resetting swinging lattice type column with a replaceable corrugated steel plate damper. Anchoring supporting plates are arranged in a crane limb and a roof limb, and the anchoring supporting plates and a rigid ground beam are connected through prestressed high-strength steel bars; the bottom of the crane limb and the bottom of the roof limb are fixed through a separated crane limb shoe beam column foot and a separated roof limb shoe beam column foot respectively, and the crane limb shoe beam column foot and the roof limb shoe beam column foot swing and lift under the action of strong shock; controllable swing of lifting and resetting motion of the column feet is achieved through elastic restoring force of the prestressed high-strength steel bars and vertical axial pressure of the column limbs, and the self-resetting capacity of the lattice type column under strong shock is enhanced. Two sets of replaceable low-yield-point corrugated steel plate dampers are arranged on the inner side of the crane leg shoe beam column foot and the inner side of the roof leg shoe beam column foot, the corrugated steel plate dampers are made of low-yield-point steel, and the good fatigue performance, welding performance and plasticity development capacity of the low-yield-point steel can be brought into full play.
本发明属于建筑结构防震减灾领域，公开了一种带可更换波纹钢板阻尼器的自复位摇摆格构式柱，本发明通过在吊车肢和屋盖肢内设置锚固支承板，通过预应力高强钢棒连接锚固支承板和刚性地梁，并且吊车肢和屋盖肢的底部分别通过分离式的吊车肢靴梁柱脚和屋盖肢靴梁柱脚固定，强震作用下，吊车肢靴梁柱脚和屋盖肢靴梁柱脚发生摇摆抬升，通过预应力高强钢棒的弹性恢复力以及柱肢竖向轴压力实现柱脚抬升与复位运动的可控摇摆，增强了格构式柱在强震下的自复位能力。吊车肢靴梁柱脚和屋盖肢靴梁柱脚内侧设置有两组可更换低屈服点波纹钢板阻尼器，波纹钢板阻尼器采用低屈服点钢材制作，可充分发挥低屈服点钢材良好的疲劳性能、焊接性能以及塑性发展能力。
