Self-resetting fabricated beam-column joint with replaceable energy-consuming elements and construction method thereof
The invention discloses a self-resetting assembly type beam-column joint with replaceable energy dissipation elements and a construction method of the self-resetting assembly type beam-column joint, and belongs to the technical field of structural engineering. The beams, the columns and the connecting pieces are manufactured in a factory, the friction energy dissipation elements are arranged at the web plates of the connecting pieces and connected through the high-strength bolts, in order to prevent the flange cover plate from interfering with other structural and non-structural members and limiting the building function, the flange cover plate is arranged to be in an inner arc shape, and good performance visibility and replacement judgability are achieved; multiple energy dissipation is achieved through friction sliding of the friction energy dissipation element and the connecting plate and deformation of the arc-shaped energy dissipation cover plate and the high-performance spring. The steel strand and the high-performance spring provide reset capacity, and the using function of the main body structure can be recovered only by replacing the arc-shaped energy dissipation plate and the high-performance spring after an earthquake; by means of the design, shaping damage occurs in the joint splicing area easy to replace, post-earthquake repair is facilitated, and the development requirement of an assembly type structure with the recoverable function is met.
可更换耗能元件自复位装配式梁柱节点及其施工方法，属于结构工程技术领域，由预制混凝土柱、预制混凝土梁及连接件装配组成。本发明梁、柱及连接件在工厂制作完成，连接件腹板处设有摩擦耗能元件并通过高强螺栓连接，为避免翼缘盖板干扰其它结构和非结构构件、限制建筑的功能将翼缘盖板设置为内弧形，且具有良好的性能可视性及更换可判性；通过摩擦耗能元件与连接板摩擦滑移、弧形耗能盖板、高性能弹簧变形的多重耗能；钢绞线及高性能弹簧提供复位能力，震后只需更换弧形耗能板及高性能弹簧即可恢复主体结构使用功能；通过设计使塑形破坏发生在易于更换节点拼接区，便于震后修复，适应于可恢复功能的装配式结构的发展需求。
