Fabricated steel frame beam-column node with double energy dissipation and shock absorption of friction and metal
The invention relates to a fabricated steel frame beam-column node with double energy dissipation and shock absorption of friction and metal. The fabricated steel frame beam-column node with double energy dissipation and shock absorption of friction and metal comprises a frame column, a frame beam, a beam-column connecting plate, a high-hardness friction plate and a metal energy-dissipation connecting assembly, wherein the frame beam is disconnected; a top flange of the frame beam is fixedly connected with a side flange of the frame column; a web of the frame beam is fixedly connected with theside flange of the frame column through the beam-column connecting plate and the high-hardness friction plate; the beam-column connecting plate is superimposed over the outer side of the high-hardness friction plate; the high-hardness friction plate and the web of the frame beam are in trapezoid shapes; a bottom flange of the frame beam is connected with the side flange of the frame column through the metal energy-dissipation connecting assembly; and the connecting assembly comprises a beam bottom flange connecting angle steel support, hemispheric cushion blocks and mini metal energy-dissipation rods. According to the beam-column node provided by the invention, the double energy dissipation and shock absorption structure of the friction plate and the metal rods is adopted, and componentswith bearing and energy dissipating capacities are used, so that a plastic rotation capacity and an energy-dissipating capacity of the node are effectively improved; and the beam-column node and a main body are connected by adopting all bolts, so that fabricated construction can be realized, and post-earthquake repair is conveniently carried out.
本发明涉及一种装配式摩擦金属双耗能减震钢框架梁柱节点，包括框架柱和框架梁、梁柱连接板、高硬度摩擦板和金属耗能连接组件，框架梁为断开式，框架梁的上翼缘与框架柱侧翼缘固定连接，框架梁的腹板通过梁柱连接板、高硬度摩擦板与框架柱的侧翼缘固定连接，梁柱连接板叠置于高硬度摩擦板外侧，高硬度摩擦板和框架梁腹板为梯形，框架梁的下翼缘通过金属耗能连接组件与框架柱的侧翼缘相连接，连接组件包括梁下翼缘连接角钢支座、半球形垫块和迷你金属耗能棒。本发明梁柱节点采用摩擦板和金属棒双耗能减震结构，使用兼具承载与耗能的构件，有效提高节点的塑性转动能力和耗能能力，梁柱节点与主体采用全螺栓连接，可实现装配式施工，且便于震后修复。
