Aplicaciones del análisis modal a la peritación de edificios civiles con estructura de fábricael caso de la edificación civil sevillana

Abstract

During the professional activity of building technicians usually appears the need to ensure the structural safety of domestic buildings with masonry structure. This activity is usually not ad¬dressed with the same intensity that in other more important buildings in which a comprehensive recognition and a large number of destructive or not destructive tests are performed Masonry structure buildings have low stresses and a stable and monolithic spatial configurations. However, they can be affected by pathological processes, which may end in a dislocation of the elements. This greatly affects the stability of the whole structure. Unlike in monumental building, in residential buildings damages may have been "camouflaged" by users. It is difficult to find them hidden by wallpaper, paneling, or behind a wardrobe. The author of the thesis is member of the research group TEP-114 which is developing a damage detection method by using simple dynamic tests to be applied in residential buildings with ma¬sonry structure. In order to produce concise results, the scope of this study has therefore been confined to the topic: the traditional sevillian domestic building. This building type has quite homogeneous mor¬phological, constructive and structural characteristics. This has allowed us to systematize the re¬search through the study of various archetypes. Theoretical studies in this thesis provide references that will allow to analyze the dynamic tests to be performed to complete the research project A review of current methods of research in this field is presented after the introductory chapter. The third chapter describes the features of the object of study, the traditional sevillian domestic building. Its geometric configuration, building characteristics and common damages. Chapter four shows the theoretical framework for selecting and evaluating the set of parameters that will be used to create the models. In addition, it displays the calculation method chosen to obtain the results that this thesis analyzes. Chapter five describes the construction of the models, by parametric design tools: Rhinoceros and Grasshopper. Models have been calculated using Sap2000 v16, performing two analysis methods, modal and PSD. Results are shown in annex 3 and discussed in Chapter 6. Chapter 7 presents the conclusions and proposes next steps to be taken to complete the research project
