Most part of Mediterranean area has been classified seismic. If for the new buildings a suitable code can be adopted and the material and the technology can give an effective contribution to the seismic resistance of the structure, for the old masonry monument only a reliable structural analysis and some specific and not much invasive retrofitting can be adopted. Among all the monumental masonry structures existing in Mediterranean area the towers have been chosen not only because more vulnerable to the horizontal actions, but also because more emblematic to study some peculiar behavior of the material. In the paper the seismic behavior of some Middle Age’s towers has been presented and analyzed. One of the most important aspect studied is the seismic vulnerability, considering also the specific non linear behavior of the material with a limited tensile resistance.

Abstract
Most part of Mediterranean area has been classified seismic. If for the new buildings a suitable code can be adopted and the material and the technology can give an effective contribution to the seismic resistance of the structure, for the old masonry monument only a reliable structural analysis and some specific and not much invasive retrofitting can be adopted. Among all the monumental masonry structures existing in Mediterranean area the towers have been chosen not only because more vulnerable to the horizontal actions, but also because more emblematic to study some peculiar behavior of the material. In the paper the seismic behavior of some Middle Age’s towers has been presented and analyzed. One of the most important aspect studied is the seismic vulnerability, considering also the specific non linear behavior of the material with a limited tensile resistance. Localization of the peak stress under horizontal loads will be discussed for this kind of structures. Some remarks and comparison on traditional and innovative reinforcing technology adopted to improve seismic resistance of the towers will be presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
