摘要
本文在国内外相关文献研究的基础上 ,先后分析了复合材料加固混凝土结构耐久性问题的由来 ,机理以及问题的解决途径。在初步的加速试验结果分析的基础上 ,研究了酸碱环境对一种高强复合纤维材料力学性能随时间的变化规律。最后 。
Based on the investigation of related references, this paper is engaged in the problem analysis on the durability of concrete structures retrofitted with fiber reinforced plastics (FRP). After the study on the mechanism of this kind of durability, some possible ways to solve this problem or extend the durability are proposed. Moreover, an accelerated laboratory testing method is conducted to investigate the basic mechanical behavior of one kind of strong glass fiber reinforced plastics (GFRP) under the corrosion environment of sulphuric acid and sodium hydroxide with different concentrations. Finally, some suggestions on design and construction are put forward to enhance the durability of concrete structures retrofitted with FRP.
