The invention discloses a semi-rigid anti-seismic reinforcing assembly and a reinforcing method for a beam-column joint, and belongs to the technical field of building earthquake resistance, the anti-seismic reinforcing assembly comprises a stress rod, a reset mechanism and a base, the stress rod comprises a front rod, the front rod is clamped by a rear cylinder, the front end of the front rod extends out of the rear cylinder, the rear cylinder comprises two clamping pieces which are in butt joint, and the two clamping pieces are in butt joint. A gap is formed between the two clamping pieces, and the two clamping pieces are fixedly connected through a high-strength bolt; the front end of the front rod is hinged to the base, and the connecting component at the rear end of the rear cylinder is hinged to the base. The reset mechanism is used for resetting the bolt when the load borne by the reinforcing assembly is increased to the maximum value corresponding to the static friction force between the front rod and the rear cylinder and then reduced to 20%-40% of the maximum value, and after the anti-seismic reinforcing assembly is used for reinforcing, the rigid area of the beam column joint cannot be obviously expanded. The rigidity of the structure cannot be obviously changed, and the overall reinforcing effect of the frame structure is better.
本发明公开了一种用于梁柱节点的半刚性抗震加固组件及加固方法，属于建筑抗震技术领域，所述抗震加固组件包括受力杆、复位机构和底座，所述受力杆包括前杆，所述前杆被后筒夹持，且前端伸出后筒，所述后筒包括两个对接的夹持件，两个夹持件之间具有间距，两个夹持件通过高强螺栓固定连接；所述前杆前端和底座铰接连接，后筒后端的连接构件和底座铰接连接；所述复位机构用于在加固组件受到的荷载增大至对应于前杆和后筒之间的静摩擦力的最大值后又降低到该最大值的20％‑40％时，复位螺栓，使用该抗震加固组件加固后不会使梁柱节点的刚性区域发生明显的扩出，结构的刚度不会发生明显的改变，框架结构的整体加固效果更好。
