中文摘要：

为了研究玻璃纤维布的拉伸强度，通过5个涂浸渍胶和未涂胶的试件进行了轴向拉伸实验。结果表明，环氧树脂不仅有粘贴和保护玻璃纤维布的作用，而且能够提高其拉伸强度。为进一步分析玻璃纤维强化塑料（GFRP）板对加固结构的影响，特制备9个单层GFRP板加固混凝土梁试件，对其进行四点弯曲加载实验，并在其中一个试件的GFRP表面粘贴了应变片，进行电测跟踪测试，从而得到结构损伤破坏过程曲线和应变片粘贴处的应变值。对比两种实验得知，GFRP板轴向拉伸强度比四点弯曲实验得到的强度大。又由测试数据和力学模型，得到FRP板轴力以及与混凝土间界面上的切应力分布曲线。

英文摘要：

To investigate the tension strength of glass fiber, axial tension experiments were carried out for five specimens with or without impregnating compounds： The experiments indicated that the epoxy resin could not only stick and protect glass fiber plates, but also increase its tensile strength. To deeply understand mechanical behavior of GFRP strengthening concrete structure, nine specimens were tested by beams＇ four-point bending experiments. One of the specimens was stick with strain gauges for tracking the failure process. Then, the damage process curves of the experiments and strain values were obtained. Comparison with two kinds of experiments, axial tension strength of glass fiber plates was greater than the strength of four-point bending test. Through the test data of concrete beam with GFRP and mechanics model analysis, the axis force and shear stress distribution of GFRP were analyzed respectively.
