    Hace justo dos años que editamos el libro Puentes (tomo I y II) Evolución-Tipología-Proyecto y Cálculo con el objetivo de poner a disposición de los alumnos de la primera promoción del Título de Graduado en Ingeniería Civil por la Escuela Técnica Superior de Ingeniería Civil de la Universidad Politécnica de Madrid un texto que cubriera de manera completa el contenido de la asignatura de Puentes de nueva creación de la que me encargué como Coordinador y Responsable. El texto se preparó para que sirviera asimismo a los profesionales de lengua castellana, considerando que había algunos aspectos en el proyecto de puentes que podrían tratarse en siguientes volúmenes.
    Por este motivo se edita este libro Puentes (tomo III) Cimentaciones-Cálculo Sísmico-Conservación/Mantenimiento con el objeto de profundizar en tres de los temas más importantes que implican el proyecto de un puente:
    - Cimentaciones de Puentes
    - Cálculo Sísmico de Puentes
    - Conservación, Mantenimiento y Rehabilitación de Puentes
    Cimentaciones de Puentes. En los capítulos 7 y 8 dedicados al cálculo de estribos y pilas se ha tratado inevitablemente el proyecto de las cimentaciones superficiales y profundas de puentes. Sin embargo el tema es de una gran amplitud que incluye muchos otros tipos de cimentación de puentes ( micropilotes, micropilotes de gran capacidad portante, pilotes de gran diámetro, elementos portantes, cajones abiertos o indios, cajones de aire comprimido, etc.) así como mejoras del terreno de cimentación de pilas y estribos (precarga, mechas drenantes, vibroflotación, compactación dinámica, jet-grouting, columnas de grava, etc.) que el autor el su experiencia profesional ha tenido que acometer en diversas ocasiones.
    Al mismo tiempo quedaban algunos aspectos como el estudio de la erosión fluvial en pilas, los recalces de cimentación y la auscultación de la cimentación, que el autor deseaba tratar en este volumen.
    Por este motivo este capítulo 11 se desarrolla con un carácter globalizador, tratando de recoger todas las técnicas existentes en la actualidad en el Proyecto y la Construcción de cimentaciones de puentes, que complementarán los aspectos iniciales tratados en los temas 7 y 8. El capítulo comienza con una introducción a las tipologías de cimentación de puentes (superficiales y profundas), continuando con las técnicas clásicas y avanzadas de reconocimiento del terreno sobre el que se va a cimentar un puente.
    Se dedica un apartado para describir las técnicas de mejora del terreno de cimentación, situación usual en los puentes que cada vez deben emplazarse en terrenos que pueden presentar cierta dificultad de soporte.
    Se dedican los dos siguientes apartados a las Cimentaciones superficiales cobre suelos y sobre rocas, con los criterios a considerar en cada caso.
    El apartado siguiente es una recopilación muy completa de los aspectos a considerar en el caso de Cimentaciones profundas tanto en los aspectos de proyecto como de construcción.
    Finalmente en el apartado 11.8 se describen las Cimentaciones especiales y en los apartados 11.9 a 11.11 aspectos relacionados con la patología de cimentaciones como la erosión fluvial, los recalces y la auscultación de cimentaciones.
    Capítulo 12: Cálculo sísmico de puentes.
    El capítulo comienza con una introducción a las Ondas Sísmicas y a la Tectónica de Placas, para continuar con el mecanismo de generación de los Terremotos y las características de los mismos. Continua con un repaso de los fallos sísmicos de puentes en los terremotos más importantes del siglo XX que dan una visión de cuáles son los elementos característicos de los puentes que suelen fallar durante la actuación de un terremoto. El apartado siguiente se dedica a describir los requisitos básicos del Proyecto Sísmico de puentes.
    Se continúa con la caracterización de la acción sísmica a considerar en función del terreno y de la aceleración del terremoto, finalizando con el procedimiento de generación de los Espectros de respuesta elástica para el caso de la Península Ibérica. En el caso de otros emplazamientos diferentes habrá que atender a la definición del espectro de respuesta elástica definido en las Normativas Nacionales.
    Se sigue con una descripción de los diferentes métodos de cálculo sísmicos.
    Los dos siguientes apartados se dedican al estudio de las comprobaciones resistentes, a las condiciones que deben cumplir los elementos resistentes de hormigón, metálicos y mixtos.
    Finalmente en los apartados 12.11 y 12.12 se estudian los elementos de unión del tablero con las pilas o estribos de los puentes y las condiciones que deben cumplirse y a los cimientos y estribos.
    Capítulo 13: Conservación, mantenimiento y rehabilitación de puentes.
    Este capítulo se dedica al importante aspecto de la conservación, mantenimiento y rehabilitación de puentes, que hoy en día con el gran acervo de estructuras de obra civil, cada vez es más necesario acometer, sobre todo el países desarrollados, así como las consideraciones de proyecto a tener en cuenta para una mayor duración de este tipo de estructuras, a tener en cuenta en fase de proyecto y construcción.
    El capítulo comienza con un repaso de la tipología de este tipo de estructuras y de las definiciones a tener en cuenta.
    A continuación se desarrollan los diferentes tipos de inspecciones a realizar en la obras de paso de carreteras y ferrocarriles, de acuerdo con un sistema global de mantenimiento.
    En función de las distintas tipologías los tres siguientes apartados se dirigen hacia las Tres tipologías básicas, dejando los puentes de fábrica que requieren un estudio especial a juicio del autor para el final:
    - Pequeñas obras de fábrica
    - Puentes de Hormigón
    - Puentes metálicos y mixtos
    En el apartado 13.7, se incide de nuevo en la socavación de pilas en ríos. Los siguientes apartados se dirigen hacia los tipos de daños más comunes en los diferentes elementos del puente:
    - Aparatos de apoyo y juntas de dilatación
    - Sistemas de contención
    - Estribos de suelo reforzado
    En el apartado 13.12 se analizan los daños producidos por impactos sobre la estructura y por último se ha dejado para el final el apartado correspondiente a las patologías de los puentes de fábrica que suelen ser los más numerosos por el gran espacio temporal durante el cual se han construido, analizando los diferentes elementos del puente y los daños que suelen producirse en ellos:
    - Cimentaciones
    - Pilas y Estribos
    - Arcos y Bóvedas
    - Rellenos
    - Tímpanos
    Terminando con los mecanismos de deterioro y los posibles procedimientos de reparación de este tipo de puentes.

    SHOCK TRANSMISSION UNITS IN CONSTRUCTION

    Shock Transmission Units in Construction

      ingenieria_arte: Shock Transmission Units in Construction

    Shock Transmission Units in Construction 
    Autor: Patel, Dinesh J

    Recent earthquakes around the world have confirmed the potential for a large seismic event to cause unprecedented levels of destruction. Shock transmission units (STUs) have been used in several projects as one of the most effective instruments in preventing widespread damage from seismic activities and structural movement. Shock Transmission Units in Construction is the first book to explore the procurement, selection, testing, installation and maintenance processes of STUs, as well as technological developments in the field of seismic protection.
    This book covers the use of STUs as both a preventative measure, fitted to a structure before a seismic occurrence, and as a seismic protection system, retrofitted to prevent further damage. Drawing on his experiences of supervising the construction of the first bridges in India and the Philippines to use STUs, Dinesh Patel explores the application of STUs on a number of different projects, including new and existing highway and rail bridges, suspension and cable stayed bridges, buildings, structures, nuclear power plants and pipelines.
    Shock Transmission Units in Construction contains case studies, photographs and illustrative diagrams to provide a clear guide to the application of STUs in numerous construction projects, as well as:
        A thorough introduction to this widely-practiced, but still little understood engineering practice, challenging critics by demonstrating the benefits and reliability of STUs in various contexts.
        A study of current STU brands and manufacturers, and the ways in which different types of STUs have been used in existing projects.
        Examples of STU application in India, Taiwan, Indonesia, Malaysia, South Korea, Hong Kong, Denmark, Rome, Italy, UK, Saudi Arabia, Turkey, Laos, Indonesia, Canada, USA and the UK.
        An analysis of the cost efficiency of retro-fitting practices.
    Shock Transmission Units in Construction aims to provide best practice guidance in helping both new and experienced engineers to select the most appropriate STU for construction projects, thus ensuring that they are used to their full potential. It is hoped that this will lead to more varied usage and the development of innovative STU derivatives for application in future projects
    About the author:
    Dinesh J. Patel graduated from the University of London, UK with a degree in Civil Engineering and obtained his Masters in Structural Engineering from the University of New South Wales, Sydney, Australia. He then supervised the design and construction of bridge structures across the world, including projects in the UK, Canada, Australia, Nigeria, Saudi-Arabia, Indonesia, India, British Guyana and the Philippines, as well as working with various international consulting engineering firms on bridge projects funded by the World Bank, the Asian Development Bank and the Japanese Government.
    Mr Patel supervised the construction of the Badiwan Bridge, Baguio - the first bridge in the Philippines to use Shock Transmission Units – an experience which enabled him to procure, select, test and install the STUs on the Second Bassein Creek Bridge, Mumbai, India. He was employed by N. D. Lea International, Canada, as resident Engineer/Team Leader to supervise the construction of this project, the first bridge in India to use Shock Transmission Units. The bridge was also awarded the first prize for innovation in construction engineering in 2001 by the Indian Institution of Bridge Engineering.
    Mr Patel has written and presented many papers on bridge engineering and shock transmission units. His paper entitled “Shock transmission units (STUs) for earthquake load distribution on the World Bank funded Second Bassein Creek Bridge in Maharashtra”, published in the Journal of the Indian Roads Congress, was awarded a certificate of merit by the Indian Road Congress in 2002.
    Mr Patel’s involvement in the Second Bassein Creek Bridge made him realise the potential for retrofitting STUs to bridges in countries with revised and upgraded earthquake zones to strengthen bridges for earthquake loading. In the absence of technical literature or specification in the Indian bridge design code on the subject of STUs, Mr Patel hopes to use this book to share his experience and best practice guidance to help future bridge engineers to procure, test and install STUs to a high standard ensure that they select the most appropriate STUs for their projects.

    STEEL CONCRETE COMPOSITE BRIDGE








    Steel-concrete Composite Bridges, 2nd edition
     Steel-concrete Composite Bridges
     Autor: Collings,David

    Steel-concrete Composite Bridges is an essential guide to the latest methods in the design and construction of steel-concrete composite bridges. Containing precise data, in-depth examples and numerous illustrations, the second edition offers guidance from the first step in bridge design through to the construction process.
    From their historic roots in post-Industrial Revolution Britain through to their modern-day use in the fast-moving and technologically changing Asian landscape, David Collings uses numerous examples from his own experience to examine how bridges can be designed and constructed to Eurocode standards using basic concepts.
    Steel-concrete Composite Bridges also covers simple beam bridges, integral bridges, continuous bridges, viaducts, haunches and double composite action, box girders, trusses, arches, cable-stayed bridges, prestressed steel-concrete composite bridges and life cycle considerations, as well as a new section on environmental issues.
    The second edition includes
        in-depth coverage of Eurocodes, their implementation and effect on new bridge-design techniques and a comparison with other international codes
        examples of ways in which theory can be combined with the practical implications of bridge construction, enabling the reader to put design concepts into practice
        comparisons of composite bridges with other types of bridges, particularly concrete structures
        an evaluation of environmental issues surrounding steel-concrete composite bridges and ways in which their carbon footprint can be lowered at the design stage.
    Steel-concrete Composite Bridges is a valuable tool for readers with an interest in the building as well as the design of bridges, providing a deeper understanding of the methods used and how they are verified against design codes.

    Combining a theoretical background with engineering practice, Design of Steel-Concrete Composite Bridges to Eurocodes covers the conceptual and detailed design of composite bridges in accordance with the Eurocodes. Bridge design is strongly based on prescriptive normative rules regarding loads and their combinations, safety factors, material properties, analysis methods, required verifications, and other issues that are included in the codes. Composite bridges may be designed in accordance with the Eurocodes, which have recently been adopted across the European Union. This book centers on the new design rules incorporated in the EN-versions of the Eurocodes.
    The book addresses the design for a majority of composite bridge superstructures and guides readers through the selection of appropriate structural bridge systems. It introduces the loads on bridges and their combinations, proposes software supported analysis models, and outlines the required verifications for sections and members at ultimate and serviceability limit states, including fatigue and plate buckling, as well as seismic design of the deck and the bearings. It presents the main types of common composite bridges, discusses structural forms and systems, and describes preliminary design aids and erection methods. It provides information on railway bridges, but through the design examples makes road bridges the focal point.
    This text includes several design examples within the chapters, explores the structural details, summarizes the relevant design codes, discusses durability issues, presents the properties for structural materials, concentrates on modeling for global analysis, and lays down the rules for the shear connection. It presents fatigue analysis and design, fatigue load models, detail categories, and fatigue verifications for structural steel, reinforcement, concrete, and shear connectors. It also covers structural bearings and dampers, with an emphasis on reinforced elastomeric bearings. The book is appropriate for structural engineering students, bridge designers or practicing engineers converting from other codes to Eurocodes.

    PEDESTRIAN BRIDGES RAMPS WALKWAYS STRUCTURES


    PEDESTRIAN BRIDGES RAMPS WALKWAYS STRUCTURES
    Andreas Keil

    Ramps, walkways, structures
    Creating integrated connections

    Pedestrian bridges need to be above all functional, but beyond this they should also relate to that which makes a location special, to its pathways, topography and context. Through their presence in the public realm, they offer the opportunity of not only connecting areas separated from each other, but also of giving a place its own identity. To draft a good pedestrian bridge, a great deal of design sensitivity is required, particularly when the bridge is being built in an inner-city area or in a sensitive landscape.But since less restrictive functional and structural requirements apply to pedestrian bridges than to road or rail bridges, pedestrian bridges offer the required design latitude for reacting to the place and use with individual solutions.
    The book at hand provides an overview of current tendencies in pedestrian bridge construction, of fundamental structural and functional requirements, of the various load-bearing systems, of application areas of the various materials and of important economic aspects. Successful real-life examples round out the volume and are meant to provide motivation to make fascinating designs a reality in interdisciplinary collaboration.

    • Fundamental knowledge ranging from design to structural support systems, from spatial installations to hanging rope constructions
    • Materials for the various design principles provide inspiration and guidance when you put them into practice
    • Successful project examples in urban and natural environments

    Gongkang Fu
     
    A succinct, real-world approach to complete bridge system design and evaluation
    Load and Resistance Factor Design (LRFD) and Load and Resistance Factor Rating (LRFR) are design and evaluation methods that have replaced or offered alternatives to other traditional methods as the new standards for designing and load-rating U.S. highway bridges. Bridge Design and Evaluation covers complete bridge systems (substructure and superstructure) in one succinct, manageable package. It presents real-world bridge examples demonstrating both their design and evaluation using LRFD and LRFR. Designed for a 3- to 4-credit undergraduate or graduate-level course, it presents the fundamentals of the topic without expanding needlessly into advanced or specialized topics.Important features include:

    • Exclusive focus on LRFD and LRFR
    • Hundreds of photographs and figures of real bridges to connect the theoretical with the practical
    • Design and evaluation examples from real bridges including actual bridge plans and drawings and design methodologies
    • Numerous exercise problems
    • Specific design for a 3- to 4-credit course at the undergraduate or graduate level
    • The only bridge engineering textbook to cover the important topics of bridge evaluation and rating
    Bridge Design and Evaluation is the most up-to-date and inclusive introduction available for students in civil engineering specializing in structural and transportation engineering.

    AERODINAMICA CIVIL EFECTOS DEL VIENTO EN EDIFICACIONES



    AERODINAMICA CIVIL.
    EFECTOS DEL VIENTO EN EDIFICACIONES Y ESTRUCTURAS
    Jose Meseguer Ruiz, Anges Sanz Andres, Santiago Pindado Carrion

    El objetivo de la aerodinámica civil es la estimación de las cargas aerodinámicas (fuerzas y momentos) que genera el flujo del aire alrededor de los cuerpos inmersos en la capa límite terrestre.

    Para determinar estas cargas de viento, en la práctica de la ingeniería existen tres posibles métodos: analítico, numérico y experimental, y el procedimiento de cálculo suele ser una combinación racional de los tres métodos y además, obviamente, de la experiencia acumulada.

    En esta línea, este libro, supone un documento básico que facilita el entendimiento de la compleja interacción entre viento y edificaciones y estructuras, y también sobre las consecuencias de las acciones del viento que es preciso encarar cuando tales acciones afectan a los usuarios de las construcciones y de sus entornos.

    WIND EFFECTS ON CABLE-SUPPORTED BRIDGES

    Wind Effects on Cable-Supported Bridges (1118188284) cover image
    WIND EFFECTS ON CABLE-SUPPORTED BRIDGES
    You-Lin Xou

    An in-depth guide to understanding wind effects on cable supported bridges, this book uses analytical, numerical and experimental methods to give readers a practical understanding. It is structured to systemically move from introductory areas through to advanced topics currently being developed from research work. The book concludes with the application of the theory covered to real-world examples, enabling readers to apply their knowledge.
    The author provides background material on the topic first of all, covering areas such as wind climate, cable-supported bridges, wind-induced damage, and the history of bridge wind engineering. Wind characteristics in atmospheric boundary layer, mean wind load and aerostatic instability, wind-induced vibration and aerodynamic instability, and wind tunnel testing are then described as the fundamentals of the subject. State-of-the-art contributions include wind and rain-induced cable vibration, wind-vehicle-bridge interactions, wind-induced vibration control, wind and structural health monitoring, and probabilistic evaluation and reliability analysis.Finally the theory is applied to the Tsing Ma suspension bridge and the Stonecutters cable-stayed bridge in Hong Kong. Amongst the world’s longest bridges, both are located in one of the world’s most active typhoon regions and equipped with incredibly comprehensive structural health monitoring systems. The book will therefore bridge the gap between the theoretical research and practical applications.
