Le cupole in terra cruda dei villaggi della regione di Aleppo (Siria):conoscenza dei dispositivi architettonici come base della prevenzione

The case of the corbelled domed buildings of the villages in the region of Aleppo is described. These buildings are made of earth bricks according to architectural solutions of particular complexity associated with building practices going into disuse and deserving to be safeguarded. The main character of these buildings is the cover system of the inhabited space (a square box of earth brick or stone) that is resolved with a paraboloid shape dome built in earth bricks arranged in rings jutting out gradually according to the scheme known as "false" dome. The study enabled to understand the peculiarity of the dome systems from the static and mechanical point of view, the realization procedures and the importance of the building materials. These data made it possible to identify the elements of weakness on which to act during maintenance in order to plan a correct prevention of damage.
