| 摘 要： | 为研究FRP(fiber reinforced plastics)加固在役混凝土柱轴压性能的试验方法,采用后张预应力法对混凝土柱施加初始应力,然后采用附加刚性千斤顶加载法进行模拟FRP加固混凝土柱轴压加载试验,得到应力-应变全曲线。研究结果表明,该试验方法能较好地实现FRP加固在役混凝土柱轴心受压试验。

| Abstract: | To study the experimental method of axial compressive test of concrete columns strengthened by bonded FRP(fiber reinforced plastics),the post-tensioned prestressing method was employed to exert initial stress to the specimens before FRP,then FRP was bonded.Axial loading method of the specimens were that one main jack exert that axial force and two jacks provided stiffness for the specimens.In this way the complete stress-strain curves of specimens were obtained.The results indicate the technical target of a... |
