Influence of stones size on the collapse of masonry bridges Influence of stones size on the collapse of masonry bridges Αφίσα σε Συνέδριο Conference Poster 2015-10-132015enMasonry bridges have been measured with geomatic techniques, including terrestial photogrammetry and terrestrial laser scanning. The collapse mechanism and load has been calculated by using finite element analysis with unilateral contact and limit analysis estimation. From parametric analysis we can prove that the minimum size of the stone near to a hinge in the arising collapse mechanism has a decisive effect on the collapse load. Nevertheless, reinforcing this weak point, could lead to a different collapse mechanism.http://creativecommons.org/licenses/by/4.0/8th GRACM International Congress on Computational Mechanics Stavroulakis Georgios Σταυρουλακης Γεωργιος Borja Conde Georgios A.
