Seismic Vulnerability of the Dey's Palace (Algiers, Algeria)

摘要

For at least five hundred years, the majestic grange of St. Anne in Montauro (CZ) has been overlooking the wonderful gulf of Squillace, placed at the core of Calabrian Ionic Coast. Masonry ramparts size (more than 7 metres high and 1,60 wide at the basis) together with the massive presence of four angular towers immediately hit even an inattentive beholder. Unfortunately, the predominant presence of grange results damaged by a clearly visible crack outline, which turned a great part of surrounding wall into a perpendicular heap of huge masonry portions. They appear disconnected and sheer, so that some panel systems are already collapsed on the north-east side of the building, included many internal constructions such as the church. The serious damage is not only due to repeated seismic events of high magnitude, that systematically run over this zone of Calabria. This article will describe in detail the methodologies and techniques of its making safe, considering the seismic and geological risk of the zone.
