$f_{cu}^0$ is the cubic compressive strength of concrete by the test, respectively; $f_{cu,m}^0$ is the average cubic compressive strength; $f_c^0$ is the calculation of the prism compressive strength, which is used in the finite element models; $E_c^0$ is the elastic modulus measured by the test, respectively.
