Book excerpt: Les ponts en arc font actuellement face au double défi de protéger leur patrimoine et de rivaliser avec d'autres formes plus récentes de structures. La conservation des ponts en arc implique de multiples impératifs : une politique saine d'inspection et de suivi, des méthodes précises d'investigation, une évaluation fiable et un éventuel diagnostic, des moyens efficaces de maintenance, de réparation, de renforcement et d'élargissement. Pendant que des ouvrages existants sont réparés et revalorisés, de nouveaux ponts en arc, de -nies traditionnelles et à " l'échelle humaine ", continuent à se construire, en utilisant des matériaux et procédés améliorés et rentables, assurant longévité et respect de l'environnement. Au premier plan de cette continuité, les concepteurs des ponts en béton, dans les hémisphères Nord et Sud, s'efforcent avec succès de réaliser des portées en arc de plus en plus longues, frôlant les 400 mètres dans les années 1980. Récemment, sur d'autres sites spectaculaires, des records de portées ont été battus par trois ponts en arc respectivement en pierre, en béton, en tubes d'acier remplis de béton. Une telle avancée ne manquera pas d'inciter les ingénieurs à rechercher des formes d'arc encore plus audacieuses et élégantes. Sur le large éventail des thèmes proposés, de nombreux auteurs, de plus de vingt-cinq pays, ont apporté des contributions majeures rappelant que les ponts en arc n'ont rien perdu de leur actualité et que, malgré les leçons assimilées de leur prestigieux héritage, leur conception stimule toujours la créativité des ingénieurs et des architectes. Ces contributions sont réunies dans le présent volume édité à l'occasion de la Troisième Conférence internationale sur les Ponts en Arc, tenue à Paris en septembre 2001. Arch bridges face at present the double challenge of protecting their heritage and competing with other more recent structural forms. The conservation of the arch bridge heritage successively requires sound inspection and monitoring policies, accurate investigative methods, reliable assessment and eventual diagnosis, efficient means for maintenance, repair, strengthening and widening. While existing structures are being repaired and upgraded, new arch bridges, of traditional forms and on a "human scale", continue to be constructed, using improved and cost-effective materials and procedures, ensuring longevity and respect for the environment. In the forefront of this continuity, concrete bridge designers, in the northern and southern hemispheres, have successfully been striving for ever larger arch spans, closely approaching 400 m in the 1980's. Lately, at other spectacular sites, span records were beaten in three arch bridges respectively using stone, concrete and slender concrete-filled steel tubes. This breakthrough may encourage engineers to seek more daring and elegant forms of arch. On the broad spectrum of the suggested topics, numerous authors, from more than twenty-five countries, have recently offered major contributions, reminding that arch bridges have nothing lost of their appeal and that, for all the lessons learnt from their prestigious heritage, their design still simulates the creativity of engineers and architects. These contributions are put together in the present volume edited on the occasion of the Third International Arch Bridge Conference held in Paris in September 2001.

Book excerpt: Modern structural engineering surprises us with the mastery and certainty with which it plans and carries out daring projects, such as the most recent metal or concrete bridges, whether they be suspension or arch bridges. On the other hand, little is yet known about the state of knowledge of construction science and techniques which, well before the arrival of modern methods based on the mechanics of deformable continua, made it possible in the past to erect the vaulted masonry structures rthat we have inherited. The fact that these have lasted through many centuries to our time, and are still in a fairly good state of conservation, makes them competitive, as far as stability and durability are concerned, with those constructed in other materials. Although it is known that the equilibrium of the arch is guaranteed by any funicular whatsoever of the loads, contained inside the profile of an arch, finding the unique solution is not such a certainty. In other words, the problem of the equilibrium of vaulted structures is 'Poleni's problem', the one for which the Venetian scientist was able to give an exemplary solution on the occasion of the assessment of the dome of St. Peter's. Arch Bridges focuses on the main aspects of the debate about the masonry arch bridge: History of structural mechanics and construction, theoretical models, analysis for assessment, numerical methods, experimental and non-destructive testing, maintenance and repair are the topics of the Conference. The breadth and variety of the contributions presented and discussed by leading experts from many countries make this volume an authoritative source of up-to-date information.

This book was released on 2009-09-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical stone arch bridges are still a major part of the infrastructure in many countries. Although this type of bridge has proven to be an efficient construction type, it often poses the problem of insufficient numerical models of the load bearing behavior. Therefore the book introduces methods to adapt life loads and introduces different types of numerical models of the load resistance respectively. The book continues with the introduction of specific damages and strengthening techniques. The book particularly focuses on the probabilistic safety assessment of historical arch bridges, for which often only limited material and structural data is available.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Masonry arch bridges which are one of the oldest forms of bridges constitute a big part of the railway and roadway network of Europe. Thus the economical, functional and social value of these structures is of great importance. Moreover, because of their esthetic and technical value they constitute part of our cultural heritage which needs to be preserved. The durability of these bridges which rises from the materials used for their construction but also from their structural behavior is remarkable. Nevertheless, they were not designed to carry the increased loads of the modern service demands. This is the reason why a big number of masonry arch bridges need to be assessed and then repaired or strengthened in order to be functional under the new necessities. It is therefore necessary to understand the constitutive structural elements of the masonry arch bridges and how each of them contributes to the overall structural behavior of the bridge. In this way, experimental methods as well as analytical ones which can predict the behavior of these structures are needed. Aiming to the better understanding of the structural behavior of masonry arch bridges, the Technological Laboratory of Structures of the Construction Engineering Department of UPC carried out an experimental campaign on real-scale bridges focusing mostly on the ultimate capacity and the collapse mechanisms. This thesis is dealing with one of those experiments on a semi-circular masonry bridge. Firstly, the structural behavior as well as the current analytical methods used to evaluate the condition of masonry arch bridges are presented. Next, a summary of the design and the construction of the bridge is described as well as the instrumentation used to record the results and the loading until failure of the structure. Then, experimental results are compared with those results provided by different analytical methods. Limit analysis using RING 2.0 was the first approach of interpreting the results. But the actual objective of this thesis is to present a finite element model able to predict the behavior of the masonry arch bridge and which can help us understand the contribution of each structural element. The results of the finite element analyses are compared with the experimental ones and some important conclusions are reached regarding the capabilities of different analytical approaches that have been used. Finally based on the gained experience some recommendations for future analytical study are given.

Available in PDF, EPUB and Kindle. Book excerpt: With majority of the Earth’s people now urban dwellers, and cities being the most efficient habitat for the utilisation of resources, it is imperative that we continue to support standards of living and efficiencies of urban areas. However, the urbanisation process has not been without its problems. While much has been done to address the original issues surrounding the quality of urban life, new challenges continue to arise. It is no longer sustainable to achieve improvements by means that require greater and greater energy consumption as we did in the past. Despite their complexity, however, cities are a great laboratory for architects, engineers, and other key professionals to apply new ideas and new technology to meet our requirements for more sustainable city environments. Containing papers presented at the latest in a series of conferences organised by the Wessex Institute of Technology, these proceedings, split in to two volumes address not just environmental, architectural, and engineering concerns, but also quality of life, security, risk, and heritage. The diversity of topics and the case studies based on existing projects make the book an important contribution to the literature on urban planning.

Download or read book 3D Numerical Simulation of Experiments on Masonry Arch Bridges written by Ignacio Brunet Coll and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Masonry arch bridges are one of the oldest civil engineering heritage preserved until today. Besides having great historical and engineering value, most are still functional and come to be approximately 60% of the total European masonry railway bridge stock. Most of these structures have to withstand increased axle loads higher than the designed ones. Consequently, many masonry bridges are damaged and need to be refurbished and in worst cases replaced. The Construction Engineering Department of the Polytechnic University of Catalonia carried out a real-scale masonry arch bridge aiming to improve the understanding of these types of structures. Since this experimental test, and based on previous studies of the same case of study, this dissertation has the objective to set up a three-dimensional numerical model to reproduce the same results obtained in the laboratory. First, a current state of the art about these types of structures is presented including a brief description of the main structural elements and their typologies, the main characteristics of masonry and a brief history of the analysis of these structures, from its beginnings in the seventeenth century till the implementation of finite element method. Moreover, the construction, material characterization and test instrumentation of the experimental test is described. The results are analysed and compared with previous analytical and numerical predictions. Finally, a non-linear analysis of a new three-dimensional model including all the main structural elements and interactions between them through the use of interface elements is performed.
