Abstract

The increasing tendency for the use and application of non – invasive strategies for structural inspection mainly on patrimonial buildings, has permitted the development of several geophysical techniques and methodologies. Current geophysical techniques, normally require a post-processing of the collected data, in which interpretation is usually not direct or trivial, and as a consequence, require experience, calibration of the results, and dedication. Of course, traditional invasive methods normally provide direct results, however, normally this kind of strategies for patrimonial structures is not desirable or not permitted, which is one of the best advantages of non invasive geophysical surveys. In this prsentation, the main geophysical methodologies for structural surveys are showed and explained, and specially, those requeird for masonry structures in seismic areas. Some real cases are shown for masonry patrimonial structures in southern Chile.
