Sliding friction energy dissipation beam column joint
The invention discloses a sliding friction energy dissipation beam column joint. A rigid beam-column joint is prone to brittle fracture, a hinged beam-column joint is allowed to rotate but cannot transmit bending moment, and the rigidity is small. The device comprises an H-shaped steel beam and an H-shaped steel column which are vertically arranged, flange positions of the H-shaped steel beam and the H-shaped steel column are connected with flange cover plates through bolts, and the flange cover plates of an upper flange and a lower flange are connected through screws; the flange cover plates at the joints of the H-shaped steel beams and the H-shaped steel columns are welded and connected through triangular steel; a connecting rod is arranged between the H-shaped steel beam and the H-shaped steel column and connected with a sliding support, and the sliding support is fixedly connected to the flange cover plate. The connecting rods are independently arranged, the using function of the structure can be recovered by replacing the connecting rods after an earthquake, earthquake energy is consumed through sliding friction of the connecting rods, and residual deformation of the structure after the earthquake can be effectively reduced through the sliding supports at the connecting positions.
本发明公开了一种滑动摩擦的耗能梁柱节点。刚性梁柱节点易发生脆性断裂，铰接梁柱节点允许发生转动，但不能传递弯矩，刚度较小。本发明包括垂向设置的H型钢梁和H型钢柱，H型钢梁和H型钢柱的翼缘位置处通过螺栓连接有翼缘盖板，上、下翼缘的翼缘盖板间通过螺杆连接；H型钢梁和H型钢柱连接处的翼缘盖板间通过三角钢焊接连接；H型钢梁和H型钢柱间设有连杆，连杆与滑动支座连接，滑动支座固定连接于翼缘盖板上。本发明连杆独立设置，震后可通过更换连杆恢复结构使用功能，通过连杆的滑动摩擦消耗地震能量，且连接处滑动支座能够有效减小结构震后的残余变形。
