| Abstract: | Earthquake damage data is of vital importance both as an indicator of the likely performance of buildings in future earthquakes,
as well as for the calibration of existing theoretical-analytical models regarding building vulnerability. The analysis of
damage data collected shortly after the August 14, 2003 Lefkada Island, Greece earthquake revealed the higher vulnerability
of masonry buildings vis-à-vis all other building typologies on the island. However, promising means in strengthening the
existing masonry stock emerge, when considering the improved performance of buildings of a dual-system of stone-masonry and
timber frame – a construction practice uniquely adopted in the island. Based on the parameterless seismic intensity scale
(psi) proposed by Spence et al. (1991) a set of preliminary vulnerability curves for the typologies of the island’s buildings are proposed. |
