ABSTRACT = {The most popular expression that considers the size effect showed in concrete structures is the size effect law of Bazant. This law depends on two coefficients <i>G<sub>f</sub></i> and <i>c<sub>f</sub></i>. For the experimental determination of these coefficients is necessary obtaining the ultimate loads, in three points bending tests, of notched beams with different sizes. In this work, a method to determine the coefficients about the results on identical beams varying the deep of the notch, is presented. The necessary values of loads are obtained by a numerical analysis with FEM that considers non linear behaviour of the concrete material. Next the proposed method is applied to experimental results of concrete specimens with different relative notch depth.},
