Observation codes: development for a method of visual inspection and damage assessment in unreinforced masonry during a post-seismic emergency

Examining a particular tradition of visual inspection methodologies based on empirical evidence represents the basis for developing a method of evaluating simple masonry structural damages during post-seismic emergencies. Integrating these observation codes allows the calibration and analysis of the survey and its measurement techniques. By taking advantage of the technologies widely available, the digital assistant (App) integrates both specialized knowledge and traditional techniques that derive from directly surveying as an analytical basis for assessing the damage. The representation of this analytical dimension of the damage is a critical aspect of establishing the correlations between the visual codes and the algorithm’s scaled assessment that determine the seismic risk and the degree of the structural integrity of the houses.
