Proceedings of the 4th International Conference on Preservation, Maintenance and Rehabilitation of Historic Buildings and Structures

This paper deals with the topi c ofthe abandonment of small villages, characteristic of Apennine Italy, investigating the causes connected to this issue and the possible "reactivation" strategies. The aim is to reverse the negative demographic trend and to exploit the role of minor historical centres. The resident population involvement and the repopulation incentive are integral part of the project concept, in order to ensure the territory regeneration, to preserve and rediscover the cultural values and local crafts. The developed methodology applied on the village of San Benedetto in Perillis (AQ), was aimed at the creation of a social, educational and tourist centre, using the most reversible construction systems, without impact on the existent building heritage and with the application of principles such as environmental sustainability, building energy efficiency, re-use logic, use of renewable sources and the choice of environmentally friendly materials. The intervention strategy on the historical constructions was conceived in three different forms: inclusion (''box in the box" type ), addition of new volumes and overlap. For the existing masonry building it was elaborated a linear analysis of local kinematics to evaluate the collapse mechanism activation. The structures were improved from the seismic point of view, thanks to the introduction of anti-tipping systems. On the other hand, the performance quality of the walls was increased, maintaining the exterior facades unchanged. The new structures were designed in XLam Wood. The applied technologies, that are considered compatible, have been verified in terms of calculations and obtainable benefits.
