In the twentieth century bridge engineers have seen many changes. Advances in technology, materials and engineers understanding of structural behaviour and methods of analysis has presented opportunities for innovation and have led to increasingly sophisticated solutions to the basic problem of providing a bridge over an obstacle. However, despite these innovative technological changes, the masonry arch bridge has shown itself to be a durable, cost-effective structure, tolerant of its modern environment and out-performing many of its competitors. In recent years arch bridges in the West have been built using reinforced concrete or steel construction; whilst in China, masonry arch bridges have continued to enjoy popularity, and there is a growing realisation in the UK that masonry arch bridges offer longevity and environmental acceptance. Arch bridges brings together current knowledge on all aspects of bridge behaviour. Leading experts from over ten counties give details of the latest developments in construction, design, analysis, repair, and maintenance. Using case histories to illustrate the methods used, this book provides an authoritative source of information which is vital to the industry if the current renaissance in arch bridge building is to be sustained.

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.

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.

Emphasis in this paper is on aspects of arch design which are not covered in many text books, such as wind stress analysis and deflection, stress amplification due to deflection, consideration of rib shortening moments, plate stiffening, and calculations for preliminary design.
