Damping ratios in structures are the most challenging modal property to predict due to the perplexity of the contributing physical mechanisms. Consequently, the inability to quantify these sources has led to only approximate baseline inherent damping estimates, making the estimation of the damping ratio at larger amplitudes an even greater task. It was previously hypothesized that the main source of damping in structures resulting in amplitude-dependence was the stressing and subsequent microcracking in slabs.This thesis outlines the steps taken to monitor a tall structure, calibrate the structural model, and examine the experimental results to identify the reasons for the vastly different modal damping responses. Non-linear modelling proved that replicating the amplitude-dependent response could be accomplished and provided insight on why the slabs' modal responses were dissimilar. Lastly, strain energies for the stressed slab regions were calculated and plotted as functions of height and displacement, ultimately substantiating slab-induced inherent damping.
