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.

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.

In the United States today, our highway infrastructure system as a whole is need of repair. This is a major issue as the American people are highly dependent upon our highway infrastructure system to keep society functioning. In 2015, the U.S. Federal Highway Administration (FHWA) reported that of America's 614,387 bridges, 20% are either structurally deficient or functionally obsolete. Also, approximately 39% of America's bridges are 50 years old and approaching the end of their design lives (ASCE, 2017). This indicates that in the coming decades, an even larger number of bridges will be demanding attention.

Explore Historic Bridge Design through the Perspective of Modern Engineering Historic Bridges:Evaluation, Preservation, and Management provides both an admiring and a technical account of bridge engineering through an exploration of several remarkable examples. From ancient China to modern-day Minnesota, the book discusses the history and structural evaluation of bridges, as well as their preservation, and restoration. With chapters written by renowned engineers, this unique resource — Compares the techniques and materials used in building three railroad bridges that traversed the Mississippi at the same site in 1865, 1887, and 1910 Investigates a legendary stone-arch bridge constructed in Ancient China in 606 A.D. Demonstrates how historians and engineers in Milwaukee found an approach to new bridge design that balances modern design standards with aesthetic interpretation Details a collaborative team approach to historic bridge management in Minnesota Considers the design and repair process of rapidly disappearing wrought iron bridges Discusses preservation of stone masonry aqueducts on the Chesapeake and Ohio Canal An educational treatise for engineers and historical preservationists, this work includes a wealth of illustrations and scientific tables. Demonstrating historic engineering significance beyond their utilitarian function, the bridges encountered in these pages are true landmarks, as worthy of emulation as they are preservation.

This report presents a literature search, findings of a survey on the current state of historic bridge rehabilitation or replacement decision making by state and local transportation agencies, and nationally applicable decision-making guidelines for historic bridges. The guidelines are intended to be used as the protocol for defining when rehabilitation of historic bridges can be considered prudent and feasible and when it is not based on engineering and environmental data and judgments. The guidelines include identification of various approaches to bringing historic bridges into conformance with current design and safety guidelines/standards, and the effect or implications of remedial action on historical significance. There are currently no such nationally applicable decision-making guidelines, but there are a variety of state and local processes and policies for managing historic bridges. Effective practices for the various processes inform the nationally applicable guidelines. The guidelines are in narrative and matrix format.
