Il progetto ADRISEISMIC: ricognizione delle tecniche costruttive nei centri storici dell’area Adriatico-Ionica. The ADRISEISMIC Project: a survey on the building techniques in the historic centres of the Adriatic-Ionian area.

The research herein presented was carried out within the issues of the Adriseismic project, funded by the Interreg Adrion program, to address seismic vulnerability through a multidisciplinary approach. The project aims at developing new integrated approaches to innovate and harmonise the normative, technical and training frameworks in the ADRION area, providing ready-to-use methods, tools and procedures that will be integrated into the existing policies and practices, thus strengthening local responses and reducing vulnerability to natural hazards. The starting point of the activities was to deepen the knowledge of the built heritage in each country involved in the project, especially the local building techniques in the historic centres of the Adriatic-Ionian area, then qualitatively correlate them to possible seismic weaknesses. The typical construction characteristics of the buildings present in these Countries, both traditional and more recent ones, were analysed. In the first phase, the investigations were conducted by collecting all possible data in the six countries involved in the project: Italy, Croatia, Albania, Serbia, Slovenia and Greece. Then, the building techniques were divided according to their structural function, defining four macro-categories: vertical masonry structures, vertical reinforced concrete structures, horizontal structures and foundation structures. In the last phase, the results collected for each country were compared, highlighting a common general framework with substantial similarities between the various countries’ construction characteristics, despite different historical-cultural events and distant regulatory practices. This result demonstrates how the availability of the same building material governs construction solutions, even though human events are very different.
