Reinforcing structure for improving earthquake resistance of earthquake-damaged RC frame structure and construction method
The invention relates to a reinforcing structure for improving earthquake resistance of an earthquake-damaged RC frame structure and a construction method. The reinforcing structure comprises frame columns and frame beams, the adjacent frame columns are connected through the frame beams, a plurality of layers of frame beams are arranged between the adjacent frame columns at intervals from top to bottom, and the adjacent frame beams are connected through buckling restrained supporting rods; and concrete is removed from seriously-damaged positions of damage positions of plastic hinge areas on beam-column joints, the frame columns and the frame beams, a repair area is formed, a cement-based composite material without the coarse aggregate is poured into the repair area for repair, the reinforcing structure is simple in structure and reasonable in design, construction is easy, the cement-based composite material without the coarse aggregate is adopted to be combined with BRB for reinforcing, and the reinforced RC frame structure can greatly enhance the bearing capacity and the lateral stiffness, improve the seismic performance of the seismic damage structure and remarkably achieve the reinforcing effect of the seismic damage RC frame structure.
本发明涉及一种提高震损RC框架结构抗震性能的加固构造及施工方法，包括框架柱、框架梁，相邻的框架柱经框架梁相连接，相邻的框架柱之间由上至下间隔设置若干层框架梁，相邻的框架梁之间经屈曲约束支撑杆相连接，梁柱节点、框架柱与框架梁上塑性铰区的破损处破损严重处剔除混凝土后形成修补区，修补区内浇筑无粗骨料的水泥基复合材料进行修补，本加固构造结构简单，设计合理，易于施工，采用无粗骨料的水泥基复合材料与BRB进行复合加固，加固后RC框架结构能大幅度增强承载力与抗侧刚度，改善震损结构的抗震性能，能显著达到震损RC框架结构的加固效果。
