| 摘 要： | 对混凝土结构用CFRP筋及其加筋混凝土梁的力学性能和感知性能进行试验研究。自行研制开发了不同直径和表面处理形式的CFRP筋。在此基础上,制作了三组各6个标准受拉试件,分别测试了CFRP筋的弹性模量、极限抗拉强度和电阻变化率,得到了相应的变化曲线;其次制作了两组各3根CFRP加筋混凝土梁,测试了梁中CFRP筋电阻随载荷增加的变化曲线。研究表明,CFRP筋具有很好的力学性能和感知性能,对于混凝土结构加强筋和结构受力状态监测具有广泛的应用前景。

| Abstract: | This paper presents test results on the mechanical and self-sensing properties of CFRP bars and concrete beams reinforced with CFRP bars. The CFRP bars were produced in different diameters and with different surface treatments. Eighteen CFRP bar specimens in three series are tested for elastic modulus, ultimate tensile strength and electrical resistance change. Six concrete beams reinforced with CFRP bars under third-point loading were tested. The curves of electrical resistance change of CFRP bars in concrete beams versus load were presented. The test results show that CFRP bars can be used as reinforcement and monitor the concrete structures mechanical properties. |
