Abstract

The cyclic behaviour of plain cylindrical concrete subjected to multidirectional compression was investigated experimentally. A total of 42 cylindrical concrete specimens from three different concrete mixes were tested. This test program was particularly focused on the strength and deformation aspects of the concrete response and the process of damage build-up. From this study, it was found that the most important response index for concrete subjected to cyclic loading was the history of damage accumulated in the microstructure which was measured in terms of volumetric strain. The degradation of the elastic stiflhess due to cyclic loads was found to be primarily a func
