Book excerpt: Actualmente, el cálculo de las deformaciones se ha convertido en uno de los aspectos claves en el diseño de piezas de hormigón armado, principalmente a causa de la reducción en el espesor de losas y el aumento de las longitudes de vano. A los efectos visuales negativos que el incremento de flechas origina se deben sumar los daños en tabiques u otro tipo de elementos no estructurales, siendo estos los problemas más comunes relacionados con las deformaciones. Los métodos de cálculo no lineales basados en un análisis paso a paso en el tiempo, de elementos lineales tipo viga, permiten determinar con rigor las curvaturas seccionales. La deformación total del elemento se obtiene mediante la integración numérica de todas las curvaturas seccionales a lo largo del elemento. Estos métodos debido a los requerimientos de tiempo y conocimiento necesarios, no suelen ser utilizados en diseño. Métodos simplificados, correctamente ajustados, son generalmente las herramientas incorporadas en las normativas a fin de realizar las verificaciones de los estados límites de servicio. Las deformaciones instantáneas están directamente relacionadas con la rigidez del elemento, por ello cuando las cargas de servicio producen fisuración en la pieza, los sistemas de análisis deben ser más precisos. Las deformaciones a largo plazo, especialmente las producidas en piezas fisuradas o esbeltas de hormigón armado, pueden causar daños en elementos no estructurales, debiendo ser estimadas con mayor precisión en la fase de diseño. La respuesta de una pieza fisurada a lo largo del tiempo, es compleja, ya que los fenómenos de fluencia y retracción conllevan modificaciones de la posición del eje neutro de la pieza, y la curvatura diferida se ve significativamente afectada por las cuantías de armadura dispuestas a tracción y compresión. En este trabajo, se proponen dos métodos simplificados para el cálculo de las deformaciones instantáneas y diferidas en elementos sometidos a flexión, los cuales están basados en el comportamiento mecánico de elementos de hormigón armado, incorporan de forma explícita, los parámetros más importantes que gobiernan el comportamiento instantáneo y el diferido de éstos. Para los métodos simplificados de cálculo de flechas diferidas, se considera que bajo carga sostenida la tensión en la armadura de tracción es constante, de acuerdo con lo observado experimentalmente y los resultados obtenidos de la simulación numérica de secciones fisuradas en el tiempo. Los resultados en las dos fórmulas simplificadas propuestas, se ajustan muy bien con aquellos obtenidos en análisis no lineal, realizado sobre un gran número de vigas virtuales. También se han obtenido resultados satisfactorios, para el método simplificado de cálculo de deformaciones a largo plazo, comparándolo con los resultados existentes de 217 ensayos realizados en vigas bajo carga sostenida, disponibles en la bibliografía.

This book was released on 2011-12 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: El presente trabajo trata sobre diferentes aspectos relativos al calculo de flechas en elementos de hormigon sometidos a solicitaciones de flexion. Se analiza la influencia de los procesos de calculo lineal y no lineal en el calculo de deformaciones y se elabora un modelo de analisis no lineal de esfuerzos. Tambien se propone un metodo simplificado de calculo de flechas instantaneas en elementos de hormigon armado, sometidos a flexion simple, considerando la influencia de la fisuracion y el efecto tension-stiffening. Otro tema abordado es la consideracion como criterio de diseno de los limites de deformacion. Por ultimo, con el apoyo de un plan experimental, se estudia el modulo de deformacion del hormigon y los valores obtenidos se contrastan con las expresiones recogidas en la normativa.

Available in PDF, EPUB and Kindle. Book excerpt: Esta nueva edición contiene ampliaciones numerosas y novedades importantes. En primer lugar se ha incorporado como Autor, Raúl Rodríguez Escribano, Ingeniero de Caminos, Canales y Puertos, y director del Área de Rehabilitación y Patología de INTEMAC. Une a su dilatada experiencia en el estudio de múltiples casos de patología motivados por las deformaciones excesivas una extraordinaria preparación informática. El libro ha pasado de catorce Capítulos y cinco Anejos de la Ia Edición a dieciocho Capítulos y siete Anejos en esta 2a Edición. Se abordan dos temas nuevos e importantes. Los Programas Informáticos incluidos con el libro permiten el cálculo de flechas de voladizos, caso no considerado en la anterior edición. Por otro lado se trata a fondo el problema del cálculo de las flechas en forjados bidireccionales (sin vigas), tema que ninguna normativa, ni nacional ni internacional, cubre. Las tablas para el dimensionamiento directo se han ampliado para cubrir estos forjados bidireccionales (sin vigas), tanto en la variante de losa maciza como en la variante aligerada. El CD que se incluye con el libro permite el cálculo de flechas mediante Programas Informáticos en entorno WINDOWS® para la Instrucción EHE-08, el Código ACI 318-08, el EUROCÓDICO EC-2 y el Método de Integración de curvaturas. Los Programas presentan siempre dos niveles. Uno simplificado (con condiciones de temperatura y humedad fijas) y otro general donde se pueden variar estas condiciones). En ambos casos los Programas contemplan el caso de cargas procedentes sólo de la planta considerada y también el caso de cimbrado de plantas sucesivas.

Book Synopsis Choice Theory: A Very Short Introduction by : Michael Allingham
Download or read book Choice Theory: A Very Short Introduction written by Michael Allingham and published by OUP Oxford. This book was released on 2002-08-22 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: We make choices all the time - about trivial matters, about how to spend our money, about how to spend our time, about what to do with our lives. And we are also constantly judging the decisions other people make as rational or irrational. But what kind of criteria are we applying when we say that a choice is rational? What guides our own choices, especially in cases where we don't have complete information about the outcomes? What strategies should be applied in making decisions which affect a lot of people, as in the case of government policy? This book explores what it means to be rational in all these contexts. It introduces ideas from economics, philosophy, and other areas, showing how the theory applies to decisions in everyday life, and to particular situations such as gambling and the allocation of resources. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Synopsis Building-in-time by : Marvin Trachtenberg
Download or read book Building-in-time written by Marvin Trachtenberg and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the pre-modern age in Europe, the architect built not merely with imagination, bricks and mortar, but with time, using vast quantities of duration as the means to erect monumental buildings that otherwise would have been impossible to achieve. Virtually all the great cathedrals of France and the rest of Europe were built by this deliberate practice, here given the name "Building-in-Time." It places an entirely new light on the major works of pre-modern Italy, from the Pisa cathedral group to the cathedrals of Milan, Venice and Siena, and from the monuments of fourteenth-century Florence to the new St Peter's. Even as this temporal regime was flourishing, the fifteenth-century Italian architect Leon Battista Alberti proposed a new one for architecture, in which time would ideally be excluded from the making of architecture ("Building-outside-Time"). Planning and building, which had always formed one fluid, imbricated process, were to be sharply divided, and the change that always came with time was to be excluded from architectural making.

Additional focus is placed on the ways occultism was implicated in Surrealist discourses on identity, gender, sexuality, utopianism and radicalism.
Book Synopsis Introduction to the Personal Software Process(sm) by : Watts S. Humphrey
Download or read book Introduction to the Personal Software Process(sm) written by Watts S. Humphrey and published by Addison-Wesley Professional. This book was released on 1996-12-20 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newest book from Watts Humphrey is a hands-on introduction to basic disciplines of software engineering. Designed as a workbook companion to any introductory programming or software-engineering text, Humphrey provides here the practical means to integrate his highly regarded Personal Software Process (PSP) into college and university curricula. The book may also be adapted for use in industrial training or for self-improvement by practicing software engineers. Applying the book's exercises to their course assignments, students learn both to manage their time effectively and to monitor the quality of their work, good practices they will need to be successful in their future careers. The book is supported by its own electronic supplement, which includes spreadsheets for data entry and analysis. A complete instructor's package is also available. By mastering PSP techniques early in their studies, students can avoid--or overcome--the popular "hacker" ethic that leads to so many bad habits. Employers will appreciate new hires prepared to do competent professional work without, as now is common, expensive retraining and years of experience.
