摘要

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-a-vis all other building typologies on the island. However, promisingmeans in strengthening the existingmasonry 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.
