Self-resetting joint with double reset system
The invention provides a self-resetting joint with a double reset system. The self-resetting joint comprises a square steel tube concrete column and a steel beam, a pin hole is formed in the middle ofa web at one end of the steel beam, a lug plate is fixedly connected to the inner side face of the square steel tube concrete column, the lug plate is provided with a pin hole and rotatably connectedwith the web at one end of the steel beam through a pin shaft, energy dissipation devices are distributed between the inner side face of the square steel tube concrete column and an upper flange of the steel beam as well as between the inner side face of the square steel tube concrete column and a lower flange of the steel beam correspondingly, and a first reset device and a second reset device are distributed on the web at one end of the steel beam. The self-resetting joint is provided with the double reset system and has the reset capability and energy dissipation capability after an earthquake, arc-shaped angle steel energy-dissipation parts are easy to replace after the earthquake, the web at the beam end adopts pin shaft connection, thus the rotating capability of the joint is improved, and the phenomenon of external expansion of the column is eliminated.
本发明是一种具有双重复位系统的自复位节点，该节点包括方钢管混凝土柱和钢梁，所述钢梁一端腹板中部设有销孔，所述方钢管混凝土柱的内侧面上固接有耳板，所述耳板上设有销孔并通过销轴与钢梁一端腹板相转动地连接在一起，所述方钢管混凝土柱的内侧面与钢梁的上翼缘和下翼缘之间分别布设有耗能装置，所述钢梁一端腹板处布设有第一复位装置和第二复位装置。本发明具有双重复位系统，在地震过后具有复位能力及耗能能力，弧形角钢耗能部件震后易于更换，梁端腹板采用销轴连接增加了节点的转动能力，消除柱子外扩现象。
