Degradation of mechanical properties of FRP bars under coupled environmental and load effects: A review
Source abstract
Abstract
Fiber-reinforced polymer (FRP) bars, with their high strength, good durability, and excellent corrosion resistance, have been identified as a suitable alternative of steel bars for addressing corrosion issues in concrete structures exposed to harsh environments. However, FRP bars are not entirely immune to environmental effects, and the degradation rate of their mechanical properties accelerates under the coupled effects of environment and loading. Consequently, the durability performance of FRP bars under such coupling effects is a critical aspect for their widespread applications. This paper reviews and summarizes the research on the degradation of FRP bars in simulated and natural environmental effects, exploring the mechanisms of performance deterioration such as the dissolution of fibers, epoxy resin matrices, and their interfaces. Furthermore, it summarizes the impact of coupled environmental and loading conditions, including the effect of stress levels, on FRP bars. The paper systematically examines and evaluates the applicability and comparability of FRP bar degradation models and offers suggestions for future research.
