Abstract

In order to analyze the whole corrosion cracking process of the cover on reinforced concrete beams, the development of generalized principle strain field on the surface of reinforced concrete beams under accelerated corrosion due to impressed current in chlorides environment was investigated through a matching pursuit processing on the digital speckle image based on digital image correlation (DIC) technology. The results indicate that the corrosion of longitudinal steel bars and stirrups in the beam both influence the generalized principle strain field on the surface of specimens. And Saint-Venant characteristics can be recognized from the distribution of generalized principle strain within the longitudinal initial cracking zone on the corroded reinforced concrete beam. DIC technology can precisely reflect the time, location and trend of cracking generation on the surface of concrete. The research method and results of this research are of great importance for the quantitative characterization on the whole cracking process due to corrosion of reinforced concrete structure.

基于DIC技术的锈蚀钢筋混凝土表面开裂

为研究钢筋混凝土梁混凝土保护层锈胀开裂的全过程,基于数字图像相关(DIC)技术,采用数字散斑图像的匹配追踪分析方法,揭示氯盐环境中外加电流加速锈蚀条件下钢筋混凝土梁表面广义主应变场的时变演化规律.结果表明：混凝土梁内纵筋与箍筋的锈蚀均对试件表面的广义主应变分布场产生影响,并且锈蚀混凝土梁表面纵向初裂位置附近的广义主应变分布具有圣维南特性；使用DIC技术可以准确判断混凝土梁表面初始开裂的时间、位置以及裂纹的走向.研究方法与成果对于量化表征钢筋混凝土结构的锈蚀开裂全过程具有重要意义.
