Valutazione del rischio sismico assistita dalla termografia IR

Masonry buildings conservation in areas of seismic risk requires the knowledge of structural geometry, details of construction and properties of materials. Heritage buildings must be safeguarded through non-destructive approaches. Thermography allows recognizing the structural damage below plaster, detecting discontinuities for added floors, cavity, filled openings, and repairs, but a precise procedure is needed. The identification and classification of masonry is addressed by means of a dedicated algorithm to find shape, type and size of elements assemblage. Both passive and active thermographic techniques have been applied in different weather conditions and time schemes.
