Self-resetting assembly type UHPC frame beam-column joint and construction method thereof
The invention relates to the field of civil engineering fabricated building structures, in particular to a self-resetting fabricated UHPC (Ultra High Performance Concrete) frame beam-column joint and a construction method thereof.The self-resetting fabricated UHPC frame beam-column joint comprises a prefabricated frame beam component, a prefabricated frame column component, ultra-high performance concrete and a self-resetting friction energy dissipater; and the prefabricated frame beam component and the prefabricated frame column component are connected at the joint by post-pouring ultra-high performance concrete. The high-strength steel bar section in the prefabricated frame beam component is arranged at the position close to the joint and extends into the frame column, the section bearing capacity is improved, and damage to the frame beam is reduced. The common reinforcing steel bar non-bonding section can release interaction between the reinforcing steel bar and concrete in the section, and damage is intensively generated in a specified area of the frame beam; the self-resetting friction energy dissipater is used for sharing energy dissipation of the connecting joint, providing certain self-resetting capacity and controlling residual deformation of the structure.
本发明涉及土木工程装配式建筑结构领域，尤其涉及一种自复位装配式UHPC框架梁柱节点及其施工方法，包括有预制框架梁构件、预制框架柱构件、超高性能混凝土、自复位摩擦耗能器，预制框架梁构件和预制框架柱构件在节点处后浇超高性能混凝土连接。预制框架梁构件内的高强钢筋区段设置在靠近节点部位并伸入框架柱内，提高截面承载能力，降低框架梁的损伤；普通钢筋非粘结区段可以释放该区段钢筋与混凝土的相互作用，将损伤集中出现在框架梁指定区域内；自复位摩擦耗能器用于分担连接节点能量耗散，并提供一定的自复位能力，控制结构残余变形。
