Book excerpt: En los ultimos anos a cobrado gran impulso una rama de la ingenieria conocida como Optimizacion Estructural, donde los problemas de diseno se reformulan en base a una o mas funciones objetivo, las cuales se quiere minimizar o maximixar, mientras se las sujeta a una serie de restricciones. Tecnicas de programacion matematica suelen ser la herramienta basica de los ingenieros que trabajan en esta area y una gran cantidad de metodos numericos y heuristicas se han desarrollado para enfrentar la alta no-linealidad de estos problemas, caracterizados por tener un gran numero de minimos locales. En esta publicacion se presenta una metodologia para el Diseno de Costo Optimo (DCO) de porticos planos de hormigon armado de edificios sometidos a cargas estaticas, basado en los requerimientos de la norma ACI 318-08. La metodologia propuesta no solo es aplicable a disenos existentes, sino que tambien puede utilizarse para hacer predisenos de proyectos en desarrollo y comprobar que las secciones no esten sobredimensionadas, llegando a considerarla como una alternativa tecnica y economicamente viable para dimensionado de proyectos de edificacion."

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Debido a ésto, se propone utilizar topologías optimizadas con respecto a su rigidez usando el método de full homogeneización, para derivar un modelo de strut-and-tie adecuado. Usando un modelo de elementos finitos no lineales para modelación de hormigón armado se comprueba la optimalidad de los elementos diseñados a partir de modelos strut-and-tie derivados de topologías óptimas usando full homogeneización, obteniéndose elementos más económicos, eficientes y con un buen comportamiento en deflexiones y fracturamiento. Además, se obtiene un ahorro sustancial del tiempo de diseño. El proceso propuesto es aplicable a elementos tridimensionales, usando diversos métodos de optimización estructural disponibles.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La corrosión del acero de refuerzo es una de las principales causas de deterioro en las estructuras de hormigón. Las principales consecuencias de la corrosión de las armaduras son la reducción de la sección transversal de la barra, el desprendimiento y fisuración del recubrimiento y el deterioro de las características de adherencia entre el hormigón y el acero. Dichas consecuencias conllevan a la disminución de la capacidad portante máxima, la pérdida de la capacidad de servicio y la seguridad estructural. En la actualidad existen dos teorías sobre si afecta o no la fisuración en la corrosión de las armaduras, llegando a ser contradictorias. La normativa española, EHE‐08 (Gobierno de España, 2008) trata la fisuración con una de las teorías en el artículo 49o del Capítulo 11, prescribiendo anchos de fisura variables en función del ambiente, que pueden llegar a condicionar el diseño, mientras que en el método del Anejo 9 no considera la influencia de la fisuración. Los códigos y normativas consideran que los criterios de durabilidad se deben satisfacer en términos de ancho de fisura, recubrimiento del hormigón y cantidad de cemento, los cuales deben ser satisfechos independientemente. Por este motivo, la fisuración tiene una gran influencia en la comprobación de la durabilidad y limitar la fisura es fundamental. Sin embargo, estos parámetros interactúan entre sí, abriendo la posibilidad de un diseño optimizado para una vida útil equivalente, no considerada en las normativas actuales, que pueden hacer que, aunque aparezcan microfisuras, la estructura siga teniendo la durabilidad adecuada para el tiempo para el que ha sido proyectado. El objetivo de este TFM es estudiar cómo afecta la fisura en el cálculo de la durabilidad y determinar cuáles son los criterios para un diseño optimizado, en el que se tengan en cuenta factores como el recubrimiento y las características del hormigón, con un ancho de fisura menor que 0,5 mm. De este modo, se hará una comparativa sobre la armadura necesaria para cumplir con la normativa y la armadura necesaria en el caso del diseño optimizado.

This book was released on 1991-02-28 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.

This book was released on 2012-01-01 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of MC2010 are to (a) serve as a basis for future codes for concrete structures, and (b) present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. MC2010 includes the whole life cycle of a concrete structure, from design and construction to conservation (assessment, maintenance, strengthening) and dismantlement, in one code for buildings, bridges and other civil engineering structures. Design is largely based on performance requirements. The chapter on materials is extended with new types of concrete and reinforcement (such as fibres and non-metallic reinforcements). The fib Model Code 2010 also gives corresponding explanations in a separate column of the document. Additionally, MC2010 is supported by background documents that have already been (or will soon be) published in fib bulletins and journal articles. MC2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement.

Book Synopsis Optimization for Decision Making by : Víctor Yepes
Download or read book Optimization for Decision Making written by Víctor Yepes and published by . This book was released on 2020-10-08 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current context of the electronic governance of society, both administrations and citizens are demanding greater participation of all the actors involved in the decision-making process relative to the governance of society. This book presents collective works published in the recent Special Issue (SI) entitled "Optimization for Decision Making". These works give an appropriate response to the new challenges raised, the decision-making process can be done by applying different methods and tools, as well as using different objectives. In real-life problems, the formulation of decision-making problems and application of optimization techniques to support decisions are particularly complex and a wide range of optimization techniques and methodologies are used to minimize risks, improve quality in making decisions, or, in general, to solve problems. In addition, a sensitivity or robustness analysis should be done to validate/analyze the influence of uncertainty regarding decision-making. This book brings together a collection of inter-/multi-disciplinary works applied to the optimization for decision making in a coherent manner.

Available in PDF, EPUB and Kindle. Book excerpt: Vacant urban land--the product of land market activity, the actions of private agents, and the policies of public agents--is an important challenge for policy makers. Vacant lots on the urban fringe and in central and interstitial areas have affected growth patterns in Latin America. Contributors to this book analyze the problems and opportunities related to vacant urban land in five cities: Buenos Aires, Argentina; Rio de Janeiro, Brazil; Quito, Ecuador; Lima, Perú; and San Salvador, El Salvador.
