Abstract
In this paper, the main characteristics of the historical structural system of the
island of Lefkada, Greece, are presented. The typical damage caused by a recent
strong earthquake (August 2003) are briefly described, since they allow for the
seismic behaviour of the system to be studied. The pathology of the structural
system seems to confirm that the structural system was conceived to sustain
earthquakes.
Keywords: earthquake, stone masonry, timber framed masonry, damages.
1 Introduction
The island of Lefkada, one of the Ionian Islands, is situated in one of the most
earthquake prone regions of Greece. A local structural system was developed
before the 19th century in Lefkada. The strong earthquake occurred in 1821
proved the adequacy of the system to sustain seismic actions. Thus, the British
Authorities (ruling the Ionian Islands at that time) imposed rules for the
construction of new houses following the main characteristics of the local
structural system. The rules, further developed and completed, constituted the
Code for Construction issued in 1827. That Code provided guidance on the
selection of building materials, on the thickness of stone masonry in the ground
floor, as well as on the maximum storey height. In addition, minimum distance is
required between adjacent buildings, to allow for better protection against fire
and earthquakes. A considerable number of buildings, built according to this
structural system are still in use in the city of Lefkada.
Keywords
earthquake, stone masonry, timber framed masonry, damages.
