Structural Analysis of Historical Constructions

Abstract

Finally, the nonlinear numerical simulations have been carried out to the collapse of the structure in order to provide an assessment of the safety factor of the structure. (a) (b) Figure 1 : Aerial view of the building (a), inside picture of the vault (b). 2 GEOMETRICAL SURVEY The geometry of the masonry vault is probably the most important factor influencing the mechanical behavior of the structure. Therefore, we started from a detailed 3D acquisition of more than 400 points, performed with an automated optical instrument (Sokkia SEF 4110R). Fig. 2a shows a section of the building, while Fig. 2b details the position of the water cushions used for the loading test, and the measurement points where displacement and/or deformations were recorded.
