Novel fabricated reinforced concrete combined joint with large deformation and restorability
The invention relates to the field of building structures, and discloses a novel fabricated reinforced concrete combined joint with large deformation and restorability. The novel fabricated reinforcedconcrete combined joint comprises a combined steel and concrete column, a steel beam and a force transfer assembly, wherein the combined steel and concrete column comprises steel columns, longitudinal load-bearing rebars and stirrups, the force transfer assembly comprises an upper flange annular connecting plate, a lower flange annular connecting plate and a web connecting plate, the flange annular connecting plates both sleeve the steel columns, the web connecting plate is vertically connected between the upper and lower flange annular connecting plates, and the steel beam is connected withthe web connecting plate through a rotary shaft. According to the novel fabricated reinforced concrete combined joint, through the force transfer assembly, steel beams in different directions can be flexibly connected, the joint construction is simple, the force transfer path is definite, and through the plastic deformation of the flange connecting plates and the rotary performance of a beam-end rotating hinge, the purpose of large deformation and energy dissipation of the joint can be achieved. The novel fabricated reinforced concrete combined joint has good overall connectivity, bearing capacity, anti-seismic performance and durability, can be replaced after being damaged, and can restore the normal using function.
本发明涉及建筑结构领域，公开了一种具有大变形和可恢复功能的新型装配式钢混组合节点，其包括钢骨混凝土柱、钢梁和传力组件；钢骨混凝土柱包括钢骨柱、纵向受力钢筋和箍筋，传力组件包括上下两块翼缘环向连接板和腹板连接板，翼缘环向连接板均套在钢骨柱上；腹板连接板垂直固定在上下两块翼缘环向连接板之间；钢梁与腹板连接板通过转动轴连接。本发明通过传力组件可以灵活连接不同方向的钢梁，连接构造简单，传力路径明确，通过翼缘连接板的塑性变形以及梁端转动铰的转动性能，可以实现节点的大变形与能量耗散的目的；本发明具有良好的整体连接性、承载能力、抗震性能和耐久性能，发生破坏后可更换并恢复正常使用功能。
