Abstract

[automatically translated] This work deals with the numerical modeling of the constitutive behavior of the so-called time sheet (the Bóvedas tabicadas) representing a traditional Catalan building techniques most widely employed by some of the greatest Spanish architects (first of all Gaudí) in the late nineteenth century [1-3]. These times are basically formed by alternate layers of approximately equal thickness in general of brick and mortar. This particular feature is studied in this work in which you want to compare the modeling of constitutive behavior considering the material as a homogeneous ideal with that obtained by shaping the material as stratified. This study allows to assess in more realistic load-bearing capacity of the Catalan vaults, the role played by the different layers of mortar and, for the purposes of structural rehabilitation, the increase of the bearing capacity of the structure itself reinforced by adding a suitable number of layers of the same material. The physical-chemical and petrographic characterization of materials is carried out by taking appropriate constituents samples a real structure, while the mechanics of structural elements is made through compression tests centered, bending and compression bending of elements taken from real and representative structures of masonry walls. Still, the mechanical characteristics of the bricks are obtained from compression and bending tests on samples extracted from real elements, while those of the mortar are obtained in accordance with current regulations. Once you determine the constitutive behavior of the experimental tests materials are played using the finite element program ADINA 8.6.1 shaping the material is as homogeneous or stratified as with the mechanical parameters obtained previously. The modeling obtained are implemented to perform computational analysis of real time on what were previously made of the load tests. The comparison between the results obtained allows to evaluate the role played by layers of mortar and their influence on the overall behavior of the material. The modeling obtained are implemented to perform computational analysis of real time on what were previously made of the load tests. The comparison between the results obtained allows to evaluate the role played by layers of mortar and their influence on the overall behavior of the material.
