Novel self-resetting energy dissipation steel structure node
The invention discloses a novel self-resetting energy dissipation steel structure node. The steel structure node comprises an H-shaped steel column and an H-shaped steel beam, one end of the H-shaped steel beam is vertically connected with a flange of the H-shaped steel column through angle steel, energy dissipation dampers are symmetrically arranged between an upper flange and a lower flange of the H-shaped steel beam and the flange of the H-shaped steel column, the energy dissipation dampers are connected with the flange of the H-shaped steel column through damper upper supports, and the energy consumption dampers are connected with the flange of the H-shaped steel beam through damper lower supports; the steel structure node further comprises a plurality of prestressed cables, the prestressed cables are symmetrically arranged on the two sides of a web plate of the H-shaped steel beam and are parallel to the span direction of the H-shaped steel beam; and a plurality of prestressed cables vertically penetrate through the flange of the H-shaped steel column at the same time and are fixedly installed on the outer side, away from the H-shaped steel beam, of the flange of the H-shaped steel column. According to the novel self-resetting energy dissipation steel structure node, the energy dissipation dampers are additionally arranged to dissipate earthquake energy, the prestressed cables are additionally arranged to improve the structure recovery performance, and the residual deformation of the structure after an earthquake is reduced.
本发明公开了一种新型自复位耗能钢结构节点，包括H型钢柱和H型钢梁，H型钢梁的一端与H型钢柱翼缘通过角钢垂直相连，H型钢梁的上下翼缘与H型钢柱翼缘之间对称设置有耗能阻尼器，耗能阻尼器通过阻尼器上支座与H型钢柱翼缘连接在一起，耗能阻尼器通过阻尼器下支座与H型钢梁翼缘连接在一起；还包括若干个预应力索，若干个预应力索对称置于H型钢梁的腹板两边，且其平行于H型钢梁跨度方向；若干个预应力索同时垂直穿过H型钢柱翼缘，并固定安装H型钢柱翼缘在远离H型钢梁的外侧。本发明一种新型自复位耗能钢结构节点通过增加耗能阻尼器来耗散地震能量，并增加预应力索来提高结构恢复性能，减小震后结构残余变形。
