Abstract

The main objective of this work is to study the size effect on the nominal strength of concrete disc specimens in Mode I loading condition. As the size of the specimens increases, the nominal strength decreases for all notched specimens. The decrease is more noticeable in the specimens with small notches. The results are also compared with the findings of the approaches based on two types of fractal based models. The test results obtained from the notched disc specimens confirm the existence of the Size Effect Law, the Multifractal Scaling Law, and the Modified Fractal Method proposed in this work.
