| Abstract: | 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. |
