纤维增强聚合物混凝土受弯构件受力性能分析

Analysis on seismic capacity for reinforced fiber-reinforced polymer concrete beam

假定其截面的弯矩—曲率关系为两折线,在此基础上确定了含纤维增强聚合物配筋混凝土受弯构件的荷载—挠度曲线,根据试验数据对建立的理论进行了验证,理论结果与试验结果具有较好的一致性,表明所采用的分析模型和分析方法具有较好的适用性。

The curve of load and deflection is predicted based on the moment-curvature relationship. The theory is verified by the experimental data and a good agreement has been found, which proves that the model and method presented here are suitable to analyze such beams with fiber reinforced polymer/plastics reinforcement.
