开展了不同配筋情况下FRP筋增强混凝土结构抗弯性能试验,系统地研究了试验梁在各级荷载作用下刚度和挠度的变化规律,并分析了结构受力特性对刚度变化的敏感性,在试验的基础上,确定了FRP筋混凝土梁的短期刚度的理论计算公式。计算结果与试验结果符合良好。

The flexural capacity experiment of concrete with FRP tendons under different reinforcement conditions has been carried out.The change law of test beam stiffness under different load levels has been systematically studied.Furthermore,the sensitivity of structural mechanical performance to stiffness change has been analyzed and its effectiveness and feasibility have been proved by experiments.Based on the experiment,theoretical calculation formula of concrete with FRP tendons on short-term stiffness has been derived.The calculation results correspond with the experimental results.
