AbstractA procedure for non-proportional size scaling of the strength of concrete based on the weakest-link statistics is proposed to synchronize strength data from specimens of different geometries and different loading modes. The procedure relies on proportional size scaling of strength to determine the parameters of the statistical model and often on finite element analysis to calculate the coefficient of the equivalent strength. The approach for non-proportional size scaling is capable to synchronize the uniaxial strength data of concrete from uniaxial tensile specimens and 3-point bending specimens, or the biaxial tensile strength data of circular plates in different loading mode. The non-transference of the uniaxial strength data to the biaxial strength data is unclear in its mechanism but possibly due to the variation of statistical distribution of microcracks with stress states in different specimens.
