Experimental Investigation of Energy Damping in Masonry Mechanisms

Abstract:

Severe earthquakes throughout the world show that existing masonry buildings are prone to suffer out-of-plane local-collapse mechanisms. In such mechanisms energy dissipation is mainly due to impacts against the remainder of the structure. Using data from an experimental campaign on free-rocking walls, estimation are suggested for the coefficient of restitution in both two-sided (façade resting on a foundation) and one-sided (façade adjacent to transverse walls) rocking. Both brick and tuff elements are considered, and the relevance of test repetition and wall height-to-thickness ratio is addressed.
