Influence of Very Old Masonry in the Seismic Damage of an Historic Tower

This paper examines the causes and the collapse of an historic masonry tower, underlining the influence of material's resistance and in particular its state of conservation. NDT tests such as sonic test on masonry evaluates wave propagation's speed through the surface layers to investigate the state of material and stratification. A FE model has been used to determine dynamic parameter of the structure, and to make a comparison than effective damages. The investigation face the relation between the material and the structural seismic response of the tower.
