Abstract
New globally oriented design methods and construction techniques have been devised in recent years to improve the seismic safety of buildings. In particular, it is now well acknowledged that seismic design must consider the system ability to dissipate energy and the effects of the lateral deformation on the response of the entire building.Two fundamental principles regarding the characteristics buildings and their resistance to seismic events has been recognized and pointed out by Latina [1] for masonry buildings. The first is the morphological and constructive regularity, with homogeneous and uninterrupted passageways, which are capable of directing and opportunely involving the actions induced by the earthquake. The second consists of the correct use of materials, which can make the walls adequately resistant to the solicitations produced by the horizontal actions of the building. These design criteria, singularly present or synergistically coexisting, are the main reason that many ancient buildings are still standing and continue to be the two fundamental principles for the sound design and construction of buildings with bearing walls in seismic areas. Studies on the effects produced by numerous earthquakes have confirmed how much of the damage and subsequent building collapses can be attributed to a structure’s irregular configuration and morphology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
