Contribution to the seismic analysis of industrial brickwork chimneys through the finite element method (Spanish text)

There are many masonry historical constructions which stability is so weak that they could fail under the action of light earthquakes, strong winds or unexpected actions.; The goal of this work is to go deep into the knowledge and understanding of the masonry behaviour and to propose a suitable constitutive model valid to be applied to the industrial chimneys from the XIX century, which are protected elements in the Comunidad Valenciana.; All this things and the clear set of the seismic behaviour of several industrial chimneys, their failure modes using different cracking criteria and making a comparison among them, finding the maximum earthquake that can be stood by these chimneys, and the proposal of a spectrum for the maximum tensile stress achieved for a particular chimney are the core and main contributions of this Thesis.; To achieve all these goals, an extensive overview of the main constitutive models collected from the scientific literature is presented and two different failure criteria are selected to be applied to all the chimneys.; All of them try to pick the low tensile resistance that characterize masonry, the non linear problem and the damage induce in the structures.; Several artificial accelerograms are generated to be introduced to the structures and the failure modes are studied.; In addition, the response spectrum for tensile stresses is generated as the medium value obtained for all the chimneys and the maximum peak ground acceleration level that each industrial chimney can stand is obtained.
