Abstract

Carbon fiber reinforced polymer (CFRP) is commonly used in civil engineering in strengthening concrete structure such as slabs, beams, and columns using externally bonding reinforcement method (EBR) or near surface mounted method (NSM. Under thermo-mechanical condition that is close to fire case condition, CFRP reinforced structures are under actions of mechanical load and elevated temperature at the same time. In the literature, the evaluation of the thermo-mechanical performance (such as fire performance) of CFRP-reinforced concrete structures requires complicated-and-expensive experimental works on full scale or large scale structures and therefore this may exceed time limit and financial budget for multi-variables observation. This paper introduces a hybrid method (numerical based and experimental validated method) to evaluate the fire performance of CFRP reinforced concrete structure over a small scale laminate-CFRP reinforced concrete specimen which is then capable to evaluate fire performance of more general CFRP reinforced concrete structures.
