Steel structure beam column connecting joint with metal round bar energy dissipation damper
The invention discloses a steel structure beam column connecting joint with metal round bar energy dissipation dampers. The connecting joint comprises a steel column, a steel beam, metal round bar damper bodies, angle steel, a web connecting piece, T-shaped connecting pieces and an auxiliary accessory. Relative movement occurs between a lower flange of the steel beam and the left T-shaped connecting piece and between a steel beam web and the web connecting piece, then friction force is generated for shock absorption, the earthquake capacity is further dissipated by combining the metal round bar energy dissipation damper bodies far away from a rotating center, a shock absorption effect is achieved, while a lower space of the beam is not excessively occupied, the rotating capacity of the joint is improved, internal force of a beam end is reduced, earthquake energy is consumed through friction between plate interfaces and metal plastic deformation of the damper bodies, the earthquake response of a structure is relieved, a structure function can be recovered only by replacing the angle steel and the metal round bar energy dissipation damper bodies after an earthquake, and very good post-earthquake repairability is achieved.
本发明公开了一种带金属圆棒消能阻尼器的钢结构梁柱连接节点，包括钢柱钢梁、金属圆棒阻尼器、角钢、腹板连接件、T形连接件及辅助配件。通过钢梁下翼缘与左侧T形连接件、钢梁腹板与腹板连接件之间发生相对的移动，继而产生摩檫力，进行减震；并结合离转动中心较远的金属圆棒消能阻尼器进一步耗散地震能力，达到减震效果。本发明在不过多占用梁的下部空间的同时，增大了节点的转动能力，减少梁端内力；利用板件界面之间的摩擦与阻尼器的金属塑性变形来消耗地震能量，减轻结构地震反应，震后只需更换角钢与金属圆棒消能阻尼器即可恢复结构功能，具有非常好的震后修复性。
