Investigating the Durability of Bent and Straight Glass Fiber Reinforced Polymer (GFRP) Rebars in Harsh Marine Environments: Pilot Study

Le résumé fourni par la source

This pilot study investigates the durability of bent and straight glass fiber reinforced polymer (GFRP) rebars in challenging marine environments.The reduction in tensile strength observed in bent rebars compared to the strength of the straight rebars is on average lower by 40%, which is considered significant.In addition, there is a lack of studies in the literature that examined the durability of bent FRP bars in harsh environments, as encountered in the UAE and Gulf region.To address this gap, an outdoor set of durability test was conducted with a specific focus on performance in saline environment.A comparative analysis will be conducted among the results of unconditioned (control) samples with those exposed to outdoor saline environment of the UAE.The output from this warranted study will answer many questions related to the utilization of such GRRP rebars in RC structural members when exposed to harsh marine environments.
