摘要： 结合已有的国内外学者的研究成果, 针对F R P筋的受力性能和F R P筋混凝土梁的受力特点, 对3根
F R P筋混凝土连续梁和2根F R P筋简支梁的受弯性能进行了试验研究。考察了F R P筋配筋率的变化对梁变形性
能的影响, 得出裂缝发展规律, 总结了 F R P筋混凝土连续梁的荷载 - 挠度变化规律; 利用试验结果, 计算和分析了
F R P筋混凝土梁的延性。

关键词:  F R P, 连续梁, 挠度, 延性, 配筋率

Abstract:

n this paper, according to the domestic and foreign scholars on the research status of FRP concrete continuous beam, the mechanical performance of FRP and loading characteristics of FRP concrete beams, the following aspects are worked. This paper makes flexural property research by means of 3 FRP continuous beams and 2 FRP simple supported beams test, this test considers reinforcement ratio impact on the beams and measures cracking load, crack propagation law, midspan and support strain, and summarize the loaddeflection of FRP concrete continuous beams. Basing on the results of the test and the research of scholars at home and abroad, this paper calculates and analysis the ductility of the FRP concrete beams.

Key words: FRP, Continuous beam, Deflection, Ductility, Ratio of reinforcement
