Abstract

High temperatures during fires pose a serious threat to the safety of building structures, significantly degrading the mechanical properties of construction materials and potentially triggering major accidents. Elevated thermal exposure reduces the mechanical performance of reinforced concrete (RC) elements, substantially undermining their overall behavior. Moreover, under high-temperature conditions, the epoxy-based bond between carbon fiber fabric and the concrete substrate undergoes pronounced thermal degradation, placing unprotected, strengthened structures at significant risk of compromised structural integrity. This study systematically reviews the existing literature, focusing on RC members strengthened with carbon fiber fabric to investigate their fire resistance limits and failure mechanisms under fire-induced high temperatures. Several insights and recommendations are proposed based on this review.
