Table 15.1 summarises the parameters used in the meso-structural models for con-
ventional concrete.
Huang et al. (2015) developed a finite elements model based on X-ray computed
tomographic (XCT) imaging to assess crack initiation and propagation in a cubic
concrete specimen compression-tested to failure. Their study showed that the joint
