We present the Master Theses incorporated into UPM Digital Archive for April.
Pérez Soriano, Laura Illeana (2014) Seguridad estructural para construcciones en zonas inundables : criterio de diseño : soluciones de minoración del riesgo de fallo. Tesis Master.
Resumen: La gestión de riesgos debe ser entendida como una determinación de vínculos entre lo que se asume como vulnerabilidad, y la forma en la que se determinarían o estimarían la probabilidad en la concurrencia de un determinado hecho, partiendo de la idea de la concurrencia de un fenómeno y las acciones necesarias que deberán llevarse a cabo. El tema de vulnerabilidad y riesgo, cada día toma más importancia a nivel mundial, a medida que pasa el tiempo es más notoria la vulnerabilidad de ciertas poblaciones ante la presencia de determinados peligros naturales como son: inundaciones, desbordes de ríos, deslizamientos de tierra y movimientos sísmicos. La vulnerabilidad aumenta, a medida que crece la deforestación. La construcción en lugares de alto riesgo, como por ejemplo, viviendas a orillas de los ríos, está condicionada por la localización y las condiciones de uso del suelo, infraestructura, construcciones, viviendas, distribución y densidad de población, capacidad de organización, etc. (ver más)
Abstract: Risk management should be understood as a determination of links between what is assumed to be vulnerable , and how that would be determined or would estimate the probability in the occurrence of a certain event, based on the idea of the occurrence of a phenomenon and necessary actions to be carried out. The issue of vulnerability and risk, every day takes more importance globally, as time passes is more notorious vulnerability of certain populations in the presence of certain natural hazards such as floods, swollen rivers, landslides and earthquakes. Vulnerability increases as it grows deforestation. The construction in high-risk locations, such as homes on the banks of rivers, is conditioned by the location and conditions of land use, infrastructure, construction, housing, distribution and population density, organizational skills, etc. (see more).
Tejerina, Adrian (2014) Seismic performance case study of bridge pile cap foundation. Tesis Master.
Abstract: The purpose of this report is to build a model that represents, as best as possible, the seismic behavior of a pile cap bridge foundation by a nonlinear static (analysis) procedure. It will consist of a reproduction of a specimen already built in the laboratory. This model will carry out a pseudo static lateral and horizontal pushover test that will be applied onto the pile cap until the failure of the structure, the formation of a plastic hinge in the piles due to the horizontal deformation, occurs. The pushover test consists of increasing the horizontal load over the pile cap until the horizontal displacement wanted at the height of the pile cap is reached. The output of this model will be a Skeleton curve that will plot the lateral load (kN) over the displacement (m), so that the maximum movement the pile cap foundation can reach before its failure can be calculated. This failure will be achieved when the load at that specific shift is equal to 85% of the maximum. The pile cap foundation finite element model was based on pile cap built for a laboratory experiment already carried out by the Master student Deming Zhang at Tongji University. (see more)
Villanueva Llauradó, Paula (2014) Condicionantes de la adherencia y anclaje en el refuerzo de muros de fábrica con elementos de fibras. Tesis Master.
Resumen: Es cada vez más frecuente la rehabilitación de patrimonio construido, tanto de obras deterioradas como para la adecuación de obras existentes a nuevos usos o solicitaciones. Se ha considerado el estudio del refuerzo de obras de fábrica ya que constituyen un importante número dentro del patrimonio tanto de edificación como de obra civil (sistemas de muros de carga o en estructuras principales porticadas de acero u hormigón empleándose las fábricas como cerramiento o distribución con elementos autoportantes). A la hora de reparar o reforzar una estructura es importante realizar un análisis de las deficiencias, caracterización mecánica del elemento y solicitaciones presentes o posibles (ver más).
Abstract: Rehabilitation of built heritage is becoming increasingly frequent, including repair of damaged works and conditioning for a new use or higher loads. In this work it has been considered the study of masonry wall reinforcement, as most buildings and civil works have load bearing walls or at least infilled masonry walls in concrete and steel structures. Before repairing or reinforcing an structure, it is important to analyse its deficiencies, its mechanical properties and both existing and potential loads (see more)
