| 摘 要： | 用耐腐蚀性纤维聚合物材料FRP筋替代钢筋为遭受钢筋锈蚀问题严重的桥梁等基础设施提供了解决问题的根本途径。对照钢筋和FRP筋的性能差异,在分析了已有的FRP加筋混凝土受弯构件的变形性设计指标基础上,依据FRP加筋混凝土受弯构件裂缝宽度的限制要求,提出了适合FRP加筋混凝土梁的设计指标,为FRP加筋混凝土梁桥的设计提供参考。

| Abstract: | The substitution of corrosion-resistant fiber reinforced polymer(FRP) bars for steel bars provides a good way for thoroughly resolving the problem of the infrastructure like the bridges with their steel bars subjected to severe corrosion.In this paper,by comparison to the differences between the performance of the FRP bars and steel bars,the design indices appropriate to the concrete beams to be reinforced by the FRP bars are proposed for reference to the design of concrete beam bridges to be reinforced by the bars on the basis of analysis of the deformability design indices of the existing concrete flexural members reinforced by the FRP bars and also in accordance with the limitations for allowed crack width in the flexural members. |
