This paper presents an extensive shaking table campaign conducted on free-standing rocking blocks subjected to recorded earthquakes. The campaign investigates different sources and degrees of variability in the rocking response, considering material irregularities, differences in block aspect ratios, and variability in the input ground motions. The experimental programme consists of the development of experimental incremental...

This study focuses on the experimental response of free-standing hard limestone blocks under free vibration. The campaign includes 120 tests, varying the block’s height-to-width ratio and considering multiple specimens to account for the aleatoric variability of the phenomenon. The study offers full reconstruction of the three-dimensional free-rocking motion, giving insights into the influence of unintended geometrical asymmet...
