Arch Bridges And Their Builders 1735 1835

This book is a comprehensive history of bridge building during the century.

This book explores what remains an under-studied aspect of Samuel Johnson’s profile as a person and writer – namely, his attitude to social improvement. The interpretive framework provided here is cross-disciplinary, and applies perspectives from social and cultural history, legal history, architectural history and, of course, English literature. This allows Johnson’s writings to be read against the peculiarities of their historical milieu, and reveals Johnson in a new light – as an advocate of social improvement for human betterment. Considering the multiplicity of narrative modes that have been employed, the book points to the blurred boundaries and overlapping between history, testimony and fiction, and argues that a future biography of Samuel Johnson has to recognise that throughout his life he valued the utilitarian aspect of his manifesto as a writer to impart a more charitable attitude in the pursuit of a more caring society.

First published in 1999, this book explores how, from the stone bridges of neoclassicism which soar out of wild woods to span pastoral valleys to the post-1750 engineer’s bridge with its links to the more industrial landscape, the bridge was a popular feature in painting throughout the period 1700-1920. Why did so many artists choose to portray bridges? In this lavishly illustrated and intriguing book, John Sweetman seeks to answer this question. He traces the history of the bridge in painting and printmaking through a vast range of work, some as familiar as William Etty’s The Bridge of Sighs and Claude Monet’s The Railway Bridge at Argenteuil and others less well known such as Wassily Kandinsky’s Composition IV and C.R.W. Nevinson’s Looking Through the Brooklyn Bridge. Distinctive characteristics emerge revealing the complex role of the bridge as both symbol and metaphor, and as a place of vantage, meeting and separation.

This text brings together current knowledge on all aspects of bridge behaviour, covering developments in construction, design, analysis, repair and maintenance. Case histories are used to illustrate the methods used.

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.
