This practical handbook is a comprehensive guide to the conservation of older bridges, commissioned by the UK Highways Agency. It provides essential guidance and recommendations for bridge conservation, repair and maintenance strategies, and proposes a new approach to best practice for bridge conservation. Conservation of Bridges covers all types of highway, foot, railway, river and canal bridges built before 1960. It comprehensively deals with state-of-the-art methods of conservation, as well as structural form and behaviour, architecture, archaeology, legislation, and attitudes to conservation. With case studies from all over the world and full colour illustrative photographs throughout, the book demonstrates what has, and can continue to be achieved in the pursuit of excellence in this field. Conservation of Bridges is essential reading for all engineers, architects and other professional groups responsible for the ongoing maintenance of a diverse bridge heritage.

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.

Structural interventions to historic buildings are however an integral part of the effort to select and update their design, historic and cultural values. Structural Design in Building Conservation deals with such design issues and shows how technical choices integrate with the planning and architectural outcomes in a conservation project. It brings together theory with current conservation technology, discussing the possibilities of structural details and strategies in architectural expression and is particularly directed at students of architectural conservation technology and practicing engineers and architects--

An Insiders’ Guide to Inspecting, Maintaining, and Operating Bridges Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present day span lengths close to two kilometers. Offers Insight from Bridge Owners across the Globe Many of these bridges carry significant traffic, and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Inspection, Evaluation and Maintenance of Suspension Bridges Case Studies gives detailed case studies of the Manhattan, Akashi Kaikyo, Tsing Ma, Storebælt East, Forth Road, Bronx–Whitestone, George Washington, Angus L. Macdonald, Mid-Hudson, Shantou Bay, and Kingston–Port Ewen Bridges. It is written by the owners and practitioners who strive to cost-effectively manage them, and applies all the inspection, evaluation, and rehabilitation methods discussed in the companion volume to give a comprehensive picture of how suspension bridges are managed. It is invaluable to everyone interested not only in suspension bridges but also in the upkeep of any bridges – students, designers, maintenance personnel, contractors, and owners.

Governments in countries like India have launched ambitious efforts to conserve natural habitats and wildlife. While in many cases achieving considerable success, these efforts have also caused serious conflicts between wildlife officials and local communities who are traditionally dependent on these resources for their livelihood. These conflicts, along with increasing developmental and commercial pressure, are threatening the future of virtually all wildlife habitats, including protected areas. The suffering that local people have been subjected to has also been enormous. Over the first half of the 1990s, alternative paths to conservation have increasingly been discussed in India and other tropical countries. To a limited extent, such alternatives arc also being tried out on the ground. A part of their inspiration comes from widespread efforts by communities themselves to regenerate and protect their surrounding areas, but there are also examples of bold initiatives by government officials to meaningfully involve people in their work. As part of a 14-month project carried out by a team at the Indian Institute of Public Administration, New Delhi, the above issues were explored through action research in three specific protected areas (Dolma Sanctuary, Rajaji National Park, Kailadevi Sanctuary) and through conceptual work on several issues related to people's involvement in conservation. A survey was also done on experiences of people's involvement in other countries, and lessons from these relevant for India. Possibilities for changing the relevant laws, including suggestions for an expanded system of protected area categories, were explored. The book contains results from all the above, a detailed bibliography on the subject, and related statements from dialogues initiated by the research team. The book will be of use to protected area managers, NGO activists, researchers, and others who are working on issues of conservation and livelihood rights.

Bridges built in timber are enjoying a significant revival, both for pedestrian and light traffic and increasingly for heavier loadings and longer spans. Timber's high strength-to-weight ratio, combined with the ease and speed of construction inherent in the off-site prefabrication methods used, make a timber bridge a suitable option in many different scenarios. This handbook gives technical guidance on forms, materials, structural design and construction techniques suitable for both small and large timber bridges. Eurocode 5 Part Two (BS EN 1995-2) for the first time provides an international standard for the construction of timber bridges, removing a potential obstacle for engineers where timber construction for bridges has not – in recent centuries at least – been usual. Clearly illustrated throughout, this guide explains how to make use of this oldest construction material in a modern context to create sustainable, aesthetically pleasing, practical and durable bridges. Worldwide examples include Tourand Creek Bridge, Canada; Toijala, Finland; Punt la Resgia, Switzerland; Pont de Crest, France; Almorere Pylon Bridge, the Netherlands.
