Importancia de la modelación numérica en la puesta en valor de estructuras patrimoniales de mampostería en zona sísmica

A numerical modeling of an artisanal ceramic brick masonry building dated from the late nineteenth century in the area of the highest seismic hazard of Argentina by the finite element method is applied. A nonlinear model is formulated, using shell elements that simulate the nonlinear behavior of the masonry structure in order to verify some actions considering existing damage. On the other hand, the structure is analyzed elastically for design and verify the proposed reinforcement. The soil foundation behavior is modeled by elastoplastic Mohr Coulom. The validity of the results obtained from field studies and laboratory tests, where low walls are made of similar thickness parameters. The efficiency of the enhancement is analyzed using identifying system techniques prior to rehabilitation and post it.
