Abstract
This paper examines the dynamic sliding response between two drums that are
basic components in forming free-standing rigid bodies that are practically
non-deformable when considering their sliding capabilities. The sliding response
of such drums is investigated experimentally and numerically. Both during the
experiments as well as in the numerical simulation specimens of such drums are
subjected to a variety of horizontal sinusoidal and simulated earthquake base
motions; these motions were generated by the Earthquake Simulator at the
Laboratory of Strength of Materials of Aristotle University of Thessaloniki,
Greece.
Keywords: rigid bodies, sliding response, coefficient of friction, sinusoidal and
earthquake excitation, shaking table.
1 Introduction
For contemporary conventional structural systems the sliding response during
strong ground motions, either at the foundation level or at the various structural
components, is ignored. However, there are important structural systems where
sliding, either at the interface between structural elements or at the supports, can
be a significant part of their earthquake response and of their overall stability.
Moreover, sliding – friction devices have been recently introduced as means of
protecting structural systems from developing undesirable performance during
expected strong ground motion.
Keywords
rigid bodies, sliding response, coefficient of friction, sinusoidal and
earthquake excitation, shaking table.
