A State-of-the-Art Review on Deformation Performance of Concrete Beams Prestressed with FRP Tendons Under Sustained Loading

College of Civil Engineering, Tongji University, Shanghai 200092, China

摘要

摘要: 持续荷载作用下,纤维增强复合材料(FRP)筋蠕变松弛和混凝土收缩徐变引起的过大的附加变形将影响预应力FRP筋混凝土(FRP-PC)梁的正常使用。通过对FRP-PC梁长期性能及其设计方法的最新研究进展进行综述,归纳了不同FRP筋的蠕变和松弛特性及其预测方法,总结了有关有黏结FRP-PC梁和体外FRP-PC梁的长期性能试验结果,介绍了基于按龄期调整有效模量法(AEMM)或基于积分型徐变表达式的FRP-PC梁变形性能时随有限元分析方法,以及相应的多参数分析结果,分析了FRP-PC梁长期变形的计算理论与简化设计方法。最后,对今后FRP-PC梁长期性能的研究方向进行了展望。

Abstract: The serviceability of FRP prestressed concrete (FRP-PC) beams under sustained loading would be affected by the excessive long-term additional deflection, which is caused by the coupled effect of creep and relaxation of FRP tendons, and shrinkage and creep of concrete. A systematic review of the research progress on the long-term performance and design methods of FRP-PC beams was carried out. Firstly, the creep and relaxation properties of FRP tendons were introduced and the prediction methods were summarized. Secondly, the relevant results related to the past 20-year-research on the experiments of long-term performance of bonded prestressed concrete beams and externally prestressed concrete beams were concluded. The time-dependent finite element analysis method based on the age-adjusted effective modulus method (AEMM) or the integral-type creep model was summarized, and the corresponding parametric results were introduced. In addition, the similarities and differences of calculation theories and the simplified methods were analyzed. Finally, the future research on the long-term performance of FRP-PC beams was suggested.
