| 摘 要： | 对配筋相同的9块碳纤维布加固的RC双向板和1块同规格的对比板进行了抗弯试验，试验板采用四点加载、简支支承。依据试验板的实际破坏形态模拟出三种塑性铰线破坏模式并提出相应的实用计算公式，计算结果与试验结果较吻合，且偏于安全，可供工程设计参考。

| Abstract: | An experimental research was carried out on the flexural behavior of nine RC two-way slabs rein- forced with CFRPS and one contrasting RC slab. The load was distributed to each slab through 4 loading points. According to the type of failure of the reinforced slabs, three yield line patterns were presented, and simple and practical calculating methods were proposed. The calculation results were in agreement with the experimental results and when the modified coefficient was considered, as compared with experimental value, the calculation results were on the conservative side. The proposed conclusion can be used for reference in design and construction of reinforcement structures. |
