Abstract
An investigation procedure was proposed by the authors to study the
vulnerability of the diffused historic building patrimony in the seismic area. The
"minimal" investigation program is to support the designers in their projects. The
knowledge of existing buildings is approached by considering different analysis
levels: history, materials, structural morphology of the wall section, observed
damage mechanisms and effectiveness of retrofitting techniques.
This paper extensively describes the investigation carried out on one of the
pilot sites, Castelluccio di Norcia. The research was carried out within the frame
of a project supported by the Civil Protection Department of the Italian Minister
Council aimed at the vulnerability analysis of the historic centres.
Keywords: masonry structures, on site and laboratory investigation,
vulnerability analysis, historic centres.
1 Introduction
The 1997 earthquake gave the occasion to learn about the effectiveness of the
repair and retrofitting techniques used on historic buildings. In fact most
retrofitting mainly performed with upgrading interventions (substitutions of
timber floors and roofs with r.c., jacketing, etc.), have caused unforeseen and
serious out-of-plane effects (large collapses, local expulsions), due to the
\“hybrid” behaviour activated between the new and the old structures [1]. That
effect was not clearly predictable by the existing assessment methods suggested
by the Italian standards, which proposed at the time analytical procedures based
on hypotheses often not easy to be satisfied in old historic stone masonry
buildings, as the effective strong connection among the structural components
