The objective of the experimental program was to conduct tests on concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars, which were exposed to severe simulated marine conditions and subjected to flexural loads. Three GFRP-RC beams, all with identical dimensions (cross-section of 300 × 200 mm and a length of 3000 mm), were utilized for this study. This included an unconditioned reference specimen, along with two conditioned beams that had undergone an accelerated aging process designed to replicate the behavior of concrete components exposed to seawater. To achieve this, all the bars and stirrups in the two conditioned beams were submerged in a tank containing a 3.5% salt solution and placed in a high-temperature chamber at 60 °C for periods of 3 and 6 months, respectively. The experimental results were presented in terms of the flexural behavior of the tested specimens, load-bearing capacity, propagation of cracking patterns, and modes of failure. The results of this study demonstrate the feasibility and effectiveness of using GFRP bars to reinforce structural elements in environments susceptible to external aggression.

摘要

The objective of the experimental program was to conduct tests on concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars, which were exposed to severe simulated marine conditions and subjected to flexural loads. Three GFRP-RC beams, all with identical dimensions (cross-section of 300 × 200 mm and a length of 3000 mm), were utilized for this study. This included an unconditioned reference specimen, along with two conditioned beams that had undergone an accelerated aging process designed to replicate the behavior of concrete components exposed to seawater. To achieve this, all the bars and stirrups in the two conditioned beams were submerged in a tank containing a 3.5% salt solution and placed in a high-temperature chamber at 60 °C for periods of 3 and 6 months, respectively. The experimental results were presented in terms of the flexural behavior of the tested specimens, load-bearing capacity, propagation of cracking patterns, and modes of failure. The results of this study demonstrate the feasibility and effectiveness of using GFRP bars to reinforce structural elements in environments susceptible to external aggression.
