Effect of size on the response of cylindrical concrete samples under cyclic loading

Abstract

© 2015 Elsevier Ltd.All rights reserved. An experimental program is carried out to investigate the relation between size and the cyclic response of cylindrical concrete samples. For this purpose, normal strength concrete samples are cast in 9 different sizes and tested under strain-controlled cyclic loads. With the 9 sizes forming an array of samples with different diameters and aspect ratios, the effect of size on peak stress and peak strain is determined. Normalized cyclic stress-strain curves are then used to evaluate the variation of cyclic parameters in terms of the diameter and aspect ratio of the sample. The results of this study show that the diameter and the aspect ratio of the samp..
