Original Abstract

Testing of concrete to assess its mechanical properties is inherent to any concrete structure’s design and production process. Eurocode defines standardized dimensions of specimens to be used, cubes and cylin- ders, to ensure representative results. However, occasionally it may be necessary to use smaller specimens, especially if testing is done with cylindrical drill-core specimens, obtained from an existing structure. The crucial geometry parameter which defines a cylindrical specimen is the slenderness ratio. It has been shown in the literature that specimens of slenderness ratios lower than two experience different mechanism of failure because of the effect of friction between the specimen and the loading platens and subsequently withstand a higher load. The effect is quantified in Eurocode by a correcting coefficient. The present contribution aims to model the phenomena with a mesoscale lattice discrete model of concrete, evaluate correcting coefficients based on the obtained data, and compare the result with experimental values and the correcting coefficients given by czech national annex to Eurocode, ČSN.
