Process Modeling and Photogrammetric Production for Structural Investigations Concerning to the Collapse of Palazzo Edilizia in Salerno (Italy)

We presents some results of a survey aimed to representation of collapse of a building and the feasibility of the modellation as support of structure analysis. The survey was made on a building in Salerno, built in Art Nouveau style, named after the “Società Anonima per l’Edilizia”, which undertook its construction. The city has considerable public and residential buildings in an eclectic style, and Liberty. In June 2007 the corner part of Palazzo Edilizia fell down suddenly. The collapse occurred at the sunup, but no victims or injured people were caused only because that part of the building contained living rooms of apartments, rather than bedrooms. Was realized an integrated survey with topographic, photogrammetric and terrestrial laser scanner techniques in order to obtain the 3D model, plans and prospects and the particular of area collapsed. The results has been an aid for the structural engineers.
