摘要

本文通过对四根大尺寸梁进行四点弯曲试验，验证了数字图像相关（DIC）技术在评估竣工梁和碳纤维增强聚合物（CFRP）加固钢筋混凝土（RC）梁的弯曲性能方面的适用性。试验期间获得的 DIC 数据与使用位移传感器和电子应变仪等传统技术测量的结果以及有限元（FE）数值模拟得出的结果进行了比较。局部位移和应变测量结果与 DIC 数据之间在所加载荷的函数关系上达到了很好的一致。此外，有限元建模生成的裂纹模式也得到了 DIC 得出的相应模式的验证。这项适用性研究预计将有助于未来实地应用 DIC 技术来监测桥梁等关键结构的 CFRP 加固构件。

Suitability of DIC in Capturing Flexural Behaviour of As-built and CFRP‑Strengthened RC Beams

In this paper, the suitability of digital image correlation (DIC) technology in evaluating the flexural behaviour of as-built and carbon fiber reinforced polymer (CFRP) strengthened reinforced concrete (RC) beams was verified by conducting a 4-point bending test on four large-size beams. The DIC data obtained during the tests were compared to the results measured using traditional techniques such as displacement sensors and electrical strain gauges, as well as the findings derived from finite element (FE) numerical simulations. A good agreement was achieved between the local displacement and strain measurements and the data from DIC as a function of the applied load. Moreover, the crack patterns generated by the FE modelling were validated by the corresponding patterns derived from DIC. This suitability study is expected to contribute to the future field implementation of DIC technology to monitor the CFRP-strengthened members of critical structures such as bridges.
