  9. Análisis del comportamiento cíclico de soportes híbridos fabricados con hormigón armado y nuevos materiales. Aplicación práctica a un edificio.

    MARTÍNEZ JAÉN, BEGOÑA
    [EN] The conventional seismic design approach used in recent years relies on the ability of structures to dissipate earthquake energy through inelastic deformations in specifically designed regions of the structural system, avoiding at the same time a general loss of stability and integrity of the structure. However, the experience of the last earthquakes shows the formation of plastic hinges located in the column-beam or column-foundation connections. For this reason, a study of columns under constant compression load and cyclic lateral loading is carried out in the present document. To ensure a dissipative and ductile overall behavior, fragile breaks or the formation of...

  12. Diseño de un dique para una defensa longitudinal en la costa de Ostende (Bélgica)

    FRUTOS PÉREZ, VÍCTOR ALBERTO DE
    [EN] Extreme storm events and a potential sea level rise are great threats for low lying areas, e.g. in Belgium, the Netherlands and parts of Germany. The wave overtopping of vertical coastal structures is identified as the main challenge of this research field that deals with coasts in low-lying countries. A typical coastal defense cross section along the Belgian coast contains a shallow foreshore (slope of up to 1:50) with sandy beaches and a steep dike (slope about 1:2) followed by a horizontal promenade (up to 30 m) in front of the cities. Storm walls of different heights and designs...

    RIOS MOSQUERA, GILBERTO JUNIOR
    [EN] Infrastructures are the main axes of development of societies, so that tending to build, improve, maintain and maintain them, is a necessary workforce. Considering that within the set of works and constructions that make up the infrastructures, there are the ports, which, when are developed efficiently, can bring benefits to the regions where they exert influence. Ports are ambitious infrastructures, because they are not composed of them in themselves, but of an entire network, which feed and support them for their correct functioning. In this context, an infrastructure management model, centered on ports, is proposed as the main axis for...

    GAMÓN OLMO, ANNA
    [ES] La Geosmina y el 2-metil-isoborneol (2-MIB) son los compuestos que generan olor y sabor más comunes que se pueden encontrar en el agua bruta. Estos compuestos son difíciles de eliminar mediante los tratamientos de agua convencionales, siendo su extremadamente bajo umbral de percepción uno de sus aspectos más retadores. A pesar de que estos problemas de olor y sabor en el agua no representan un peligro para la salud humana, causan una alerta en los consumidores, que dejan de utilizar esta agua. Tal es su detectabilidad que en cuanto aparece un episodio de sustancias sápidas, las quejas por parte...
