Extreme event populations are encountered in all domains of civil engineering. The classical and Bayesian statistical approaches for describing these populations are described and compared. Bayesian frameworks applied to such populations are reviewed and critiqued. The present Bayesian framework is explained from both theoretical and computational points of view. Engineering judgement and regional analyses can be used to yield a distribution on a parameter set describing a population of extremes. Extraordinary order events, as well as known data, can be used to update the prior parameter distribution through Bayes theorem. The resulting posterior distribution is used to form a compound distribution, the basis for estimation. Quantile distributions are developed as are linear transformations of the parameters. Examples from several domains of civil engineering illustrate the flexibility of the computer program which implements the present method. Suggestions are made for further research. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

El Perú presenta diversas eventualidades como las lluvias, que retrasan distintas actividades que promueven el crecimiento económico del país. Las zonas urbanas necesitan una mejora continua del entorno con mejores infraestructuras para promover el crecimiento y reducir los accidentes. En la actualidad, se necesita fomentar por el medio local soluciones innovadoras para la evacuación de altas precipitaciones. El concreto permeable es un tipo de concreto cuya tecnología permite que el agua discurra a través de su estructura por la alta porosidad que posee a diferencia del concreto tradicional. Es fabricado de agregado grueso y material cementante, con un bajo porcentaje de finos de hasta el 10%. Esta investigación consiste en proponer un diseño de mezcla de concreto permeable de f’c=175kg/cm² aplicado en veredas que satisfaga distintos requerimientos establecidos por las normas CE010 de Pavimentos Urbanos, ACI 211.3R, ACI 522R-10 y los propios de la zona de aplicación. Para ello se realizó una batería de 12 diseños de mezcla con relaciones a/c 0.30, 0.35 y 0.38; agregados de HUSO 7 y 67; cementos portland tipo 1 Sol y Quisqueya; y aditivo Z fluidizante SR. Se realizaron ensayos en estado fresco: Slump, peso volumétrico y contenido de vacíos; y en estado endurecido: Resistencia a la compresión y flexión, y permeabilidad. Finalmente se realizó un prototipo con el diseño que presentó mejores características con el propósito de validar la investigación y se realizo un comparativo entre las veredas de concreto permeable y tradicional. / Peru presents various eventualities such as rainfall, which delay different activities that promote the country's economic growth. Urban areas need continuous improvement of the environment with better infrastructure to promote growth and reduce accidents. At present, innovative solutions for the evacuation of high rainfall need to be promoted through the local environment. Permeable concrete is a type of concrete whose technology allows water to flow through its structure due to the high porosity it possesses, unlike traditional concrete. It is made of coarse aggregate and cementitious material, with a low percentage of fines of up to 10%. This research consists in proposing a permeable concrete mix design of f'c = 175kg / cm² applied in sidewalks that satisfies different requirements established by the CE010 standards of Urban Pavements, ACI 211.3R, ACI 522R-10 and those of the area of application. For this, a battery of 12 mixing designs with a / c ratios of 0.30, 0.35 and 0.38; aggregates of HUSO 7 and 67; portland cements type 1 Sol and Quisqueya; and fluidizing Z additive SR. Fresh tests were performed: Slump, volumetric weight and void content; and in a hardened state: resistance to compression and flexion, and permeability. Finally, a prototype was made with the design that presented better characteristics with the purpose of validating the research and a comparison was made between the permeable and traditional concrete sidewalks. / Tesis
