Abstract

fetched live from OpenAlex

As the use of Fibre-Reinforced Polymer (FRP) materials continues to expand into the structural repair market, concerns over the performance of these materials in fire conditions are now at the forefront of research. While externally bonded FRP sheets have been shown to successfully enhance the flexural and shear capacity of bridges and other structures, their application in interior spaces, where fire is a significant concern, remains questionable in light of these materials’ comparatively poor resistance to elevated temperatures. This paper presents the results of an ongoing study to document the performance of FRP-strengthened reinforced concrete beam-slabs exposed to fire. With such experimental results, fireproofing materials have the potential to earn standard performance ratings, which are essential to the design engineer and necessary for the continued increase of FRP applications worldwide. A brief synopsis of existing literature related to FRP behavior at high temperature is provided, in addition to a review of the current fire endurance criteria for structural members. Two large-scale concrete beam-slab assemblies were strengthened with FRP sheets and protected with a two-part patented fire insulation system. The results of fire tests performed on these specimens are presented herein, with emphasis placed on the temperatures measured in the specimens during fire exposure. The data obtained from the tests served to validate a numerical heat transfer model, which predicts the temperature within a strengthened and insulated reinforced concrete beam-slab assembly. Test results and model data indicate that appropriately designed and insulated FRP-strengthened beam-slab assemblies can achieve fire endurances of four hours or more.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
