Popis:	To evaluate how the size effect affects the stresses developed along the compression chord in a beams subjected to shear forces, a simplified experimental program was developed on 50 prismatic specimens subjected to a splitting test. The studied parameters were: dimensions, slenderness, concrete compressive strength, and maximum aggregate size. To capture the post-peak behavior of the concrete, the load was introduced as a function of the crack width, through appropriate control algorithms. Digital Image Correlation (DIC) in a 2D configuration has also been used to accurately capture the formation, width and propagation of cracks to corroborate the experimental measurements. The financial support provided by the Spanish Ministry of Economy and Competitiveness (MINECO) and the European Funds for Regional Development (FEDER), through the Research projects: BIA2015-64672-C4-1-R and BIA2017-84975-C2-2-P and through the Excellence network BIA2015-71484-REDT.
