PHILANTHROPIC FOUNTAIN OF KORNAROU SQUARE: USING SFM TO CALCULATE THE FOUNTAIN’S GEOMETRIC CHARACTERISTICS IN ORDER TO DETERMINE ITS INELASTIC DYNAMIC RESPONSE

[EN] This paper proposes the use of Structure from Motion (SfM) techniques to survey inaccessible monument structures and presents its application on capturing Kornarou Square's philanthropic fountain in Heraklion, Crete. A series of aerial and terrestrial photos of the fountain were combined in order to build the 3D geometry of the monument using Agistoft's Photoscan. This 3D model was used to study the dynamic behavior of the fountain. Its response was determined through multiple inelastic dynamic analyses. The analysis results were summarized in the average dynamic curve
