DYNAMIC CHARACTERISTICS OF MALTESE BUILDINGS P.Galea 1 , T. Micallef 1 , M. Mucciarelli 2 , S.

The Maltese archipelago is classified as having low-to-moderate seismic hazard with agenerally low level of seismic activity around the island, while being exposed to rare, large events originating at nearby major tectonic features such as in SE Sicily. However, being exposed to a high building density means that the Maltese Islands are subjected to a considerable seismic risk. To reduce such risks it is important to understand how buildings will respond to seismic shaking and predict possible resonance phenomena. Building response to ground motion is as complex as the ground motion itself, and depends on numerous properties of the building. Seismic waves released at earthquake sources approach the base of a building from a given direction. Horizontal and vertical ground motions lead to different types of forces on the building, such as tension, shear, compression, bending or torsion forces. As discussed by Albarello (2013), ground shaking can be described as a linear combination of simple harmonic oscillations. For this reason, an earthquake’s effect on a structure can be mainly studied by considering the effect of a single oscillation.Buildings experience mo stly horizontal ground motion due to seismic body S waves generated during an earthquake. If these horizontal distortions are large, the damage may be disastrous. In fact, most buildings are designed to resist lateral forces in order to minimize the amount of damage GNGTS 2014 S essione 2.3 387
