| Abstract: | When the deformation of carbon fiber reinforced concrete (CFRC) was within the range of elasticity,its resistance increased reversibly under tension strain and decreased reversibly under compression strain. According to the stress-strain condition at different parts,when CFRC was laid selectively,not only the self-monitoring of the deformation in smart concrete structure was attained,but also the sensitivity and the stability were improved greatly. This approach was verified theoretically and experimentally and some ideas of further investigations of smart concrete structures were provided. |
