This study is an analytical research on the size effect of concrete flexural-compressive strength. The meso-scale finite element method was used to analyze various sizes of specimens. As a result of the analysis, the size effect that the flexural-compressive strength becomes smaller as the size of specimen becomes bigger is analytically confirmed.
