机敏混凝土结构变形的自诊断

Self-monitoring of the deformation in smart concrete structures

从理论和实验两方向证明 :利用结构的受力变形特点和CFRC的功能特性 ,合理地敷设CFRC ,不但可实现机敏混凝土结构变形的自诊断 ,而且可大大提高其灵敏系数和稳定性 ,同时也实现了温度补偿 .

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.
