现有钢筋混凝土框架结构中梁、柱、节点因设计不当或施工事故，发生梁、柱、节点不能满足强柱弱梁、强节点弱构件的抗震设计原则，针对强柱弱梁、梁弱弯弱剪、梁纵筋锚固不足等４个节点试件进行了低周反复加荷对比试验，从破坏过程分析了梁、柱、节点核心区不同粘钢加固方案的效果。试验结果表明：粘钢加固对提高构件强度、改变框架破坏机制及增加变形能力具有良好的效果。并全面地分析了试件加固方案的优劣，初步给出了粘钢加固节点的构造措施和更合理的加固方法。
In the existing reinforced concrete frame structure, the beams, columns, and nodes are not suitable for the seismic design of beams with weak columns and strong nodes due to improper design or construction accidents. Weak shear and insufficient longitudinal anchorage of the longitudinal reinforcement were tested in the low-cycle repeated loading test. The effects of different reinforcement schemes in the core of the beam, column and node were analyzed from the failure process. The experimental results show that the sticking steel reinforcement has a good effect on improving the strength of the component, changing the failure mechanism of the frame and increasing the deformation capacity. The advantages and disadvantages of the reinforcement scheme of the test piece are analyzed comprehensively. The construction measures and the more reasonable reinforcement methods are given preliminarily.
