The effects of cutouts in joists on the vibrational response of wood floors
… root-mean-squared (RMS) acceleration, log-decrement damping ratio, and modal damping ratios. Included in the thesis are the results of a static test (load sharing) performed on the floors with and without cutouts in the joists.

Statnamic Lateral Load Testing and Analysis of a Drilled Shaft in Liquefied Sand
… is within the range of values derived from the log decrement method. The computer program LPILE was then used to compute the load-deflection curves in comparison with the response from the field load tests. Analyses were performed using a variety of p-y curve shapes proposed for liquefied sand. …

Evaluation of analytical and experimental methods to predict constrained layer damping behavior
… developed by Han [30] and the time domain of log decrement. Model comparison of finite elements to experimental results showed good trend prediction correlation. Only fair prediction of absolute loss factors was achieved, possibly due to the difficulty in characterization of viscoelastic …
