THE SUGGESTIONS ON COMPUTING CRITICAL REINFORCEMENT RATIO FOR CONCRETE BEAM REINFORCED WITH FRP BARS
-
摘要: 在明确定义FRP筋混凝土梁两种破坏模式的基础上,给出了FRP筋普通混凝土及预应力混凝土梁的界限配筋率的计算建议,可为今后的研究与设计提供参考。Abstract: Based on the definition of two failure modes of concrete beam reinforced with FRP bars,the suggestions on computing critical reinforcement ratio for concrete beam reinforced with FRP bars and that of concrete beam reinforced with prestressed FRP bars are presented,which may be use for reference to further study and design.
