ABSTRACT: This article aims to popularize the methods for determining the vibratory damping ratio, to explain the various mathematical and physical theorems
related to the establishment of literal expressions. Vibration damping is an essential parameter to
reduce the dynamic responses of structures. The study aimed at its
determination is necessary and essential for the safeguard of buildings and
human lives during the earthquake. Among the main methods studied in this article, the
free vibration attenuation method seems to be easy to implement but requires a
state-of-the-art device to capture the responses. In addition to this device,
the other methods require other equipment for the vibration of the system and the
transformation of the responses in the frequency domain.
