Fabricated steel structure beam-column joint with replaceable arc-shaped energy consumption plates
The invention relates to an assembly type steel structure beam-column joint with replaceable arc-shaped energy dissipation plates. The assembly type steel structure beam-column joint mainly comprises an H-shaped steel column, an H-shaped steel beam, a plurality of sets of arc-shaped energy dissipation plates and a plurality of connecting pieces. According to the technical scheme, the H-shaped steel column is connected with the upper flange and the lower flange of the H-shaped steel beam through the T-shaped piece and the energy consumption device composed of the multiple sets of arc-shaped energy consumption plates so as to bear the bending moment effect; the H-shaped steel column is connected with a web of the H-shaped steel beam through a T-shaped piece so as to bear vertical shearing force. Under the action of an earthquake, the beam component can rotate around the end part of the upper flange, so that the damage to a floor slab is effectively reduced; and the post-earthquake damage of the joint is concentrated on the arc-shaped energy consumption plate which is easy to detect and replace, and the main body beam column component is not damaged, so that the post-earthquake recovery capability of the joint is greatly improved. In addition, the geometric configuration of the arc-shaped energy consumption plate can be flexibly adjusted, so that the mechanical parameters of the joint have high adjustability.
本发明涉及一种带可更换弧形耗能板的装配式钢结构梁柱节点，主要包括H形钢柱、H形钢梁、多组弧形耗能板以及多个连接件。本技术方案的H形钢柱与H形钢梁的上翼缘和下翼缘分别通过T形件和多组弧形耗能板组成的耗能装置连接，以承担弯矩作用；H形钢柱与H形钢梁的腹板则通过T形件连接，以承担竖向剪力。地震作用下，梁构件可以绕着上翼缘端部转动，从而有效降低对楼板造成的损伤；并且节点的震后损伤集中于易检测、易可更换的弧形耗能板，而主体梁柱构件保持无损，极大提高了节点的震后恢复能力。此外，弧形耗能板几何构形可以灵活调节，从而使节点的力学参数具有高度的可调节性。
