Surface cracks on concrete are obvious and easily identified, which could be adopted as a failure index. Monitoring the characteristics and distribution of surface cracks of concrete is conducive to understand the mechanical behaviors and potential failure mechanism of concrete structures. In measurement of the cracks, the digital image measurements, compared with traditional artificial techniques, have advantages in terms of automation and accuracy. As a result, digital image measurements are applied in this research to measure the characteristics of surface cracks during the failure of concrete samples. The crack characteristics include crack density, maximum crack length, maximum crack width, and crack spacing, etc. With the data of uniaxial compressive tests of concrete samples, we can obtain the regressive laws between concrete strength and crack characteristics. These results can be verified with the surface cracks obtained from large-scale experiments of reinforced concrete structures. Chang-Wei Huang 黃仲偉 2013 學位論文 ; thesis 123 zh-TW |
