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.

Design of Welded Steel Structures: Principles and Practice provides a solid foundation of theoretical and practical knowledge necessary for the design of welded steel structures. The book begins by explaining the basics of arc welding, describing the salient features of modern arc welding processes as well as the types and characteristics of welded joints, their common defects, and recommended remedial measures. The text then:
Addresses the analysis and design of welded structures
Explores the design of joints in respect to common welded steel structures
Identifies the cost factors involved in welded steelwork
Design of Welded Steel Structures: Principles and Practice draws not only from the author’s own experience, but also from the vast pool of research conducted by distinguished engineers around the globe. Detailed bibliographies are included at the end of each chapter

Structures buckling under tensile dead load - paper.

Abstract: Some 250 years after the systematic experiments by Musschenbroek and their rationalization by Euler, for the first time we show that it is possible to design structures (i.e. mechanical systems whose elements are governed by the equation of the elastica) exhibiting bifurcation and instability (‘buckling’) under tensile load of constant direction and point of application (‘dead’). We show both theoretically and experimentally that the behaviour is possible in elementary structures with a single degree of freedom
and in more complex mechanical systems, as related to the presence of a structural junction, called ‘slider’, allowing only relative transversal displacement between the connected elements. In continuous systems where the slider connects two elastic thin rods, bifurcation occurs both in tension and in compression, and is governed by the equation of the elastica, employed here for tensile loading, so that the deformed rods take the form of the capillary curve in a liquid, which is in fact governed by the equation of the elastica under tension. Since axial load in structural elements deeply influences dynamics, our results may provide application to innovative actuators for mechanical wave control; moreover, they open a new perspective in the understanding of failure within structural elements.

Structures buckling under tensile dead load - Video.

Buckling of a straight elastic column subject to compressive end thrust occurs at a critical load for which the straight configuration of the column becomes unstable and simultaneously ceases to be the unique solution of the elastic problem (so that instability and bifurcation are concomitant phenomena). Buckling is known from ancient times: it has been experimentally investigated in a systematic way by Pieter van Musschenbrok (1692–1761) and mathematically solved by Leonhard Euler (1707–1783), who derived the differential equation governing the behaviour of a thin elastic rod suffering a large bending, the so-called ‘elastica’ (see Love 1927).
This video shows bifurcation and instability experiments of elastic structures subject to tensile dead load. This research was published in the journal Proceedings of the Royal Society, in the paper: Structures buckling under tensile dead load by D. Zaccaria, D. Bigoni, G. Noselli and D. Misseroni.

The Encyclopedia of Earthquake Engineering is designed to be the authoritative and comprehensive reference covering all major aspects of the science of earthquake engineering, specifically focusing on the interaction between earthquakes and infrastructure. The encyclopedia comprises 271 contributions. Since earthquake engineering deals with the interaction between earthquake disturbances and the built infrastructure, the emphasis is on basic design processes important to both non-specialists and engineers so that readers become suitably well-informed without needing to deal with the details of specialist understanding. The content of this encyclopedia provides technically inclined and informed readers about the ways in which earthquakes can affect our infrastructure and how engineers would go about designing against, mitigating and remediating these effects. The coverage ranges from buildings, foundations, underground construction, lifelines and bridges, roads, embankments and slopes. The encyclopedia also aims to provide cross-disciplinary and cross-domain information to domain-experts. This is the first single reference encyclopedia of this breadth and scope that brings together the science, engineering and technological aspects of earthquakes and structures.

Engineers face numerous uncertainties in the design and development of products and processes. To deal with the uncertainties inherent in measured information, they make use of a variety of statistical techniques. This outstanding text presents single-variable statistical distributions that are useful in engineering design and analysis. It lists significant properties of these distributions and describes methods for estimating parameters and their standard errors, constructing confidence intervals, testing hypotheses, and plotting data. Each distribution is worked through typical applications. Figures are used extensively to clarify concepts. Methods are illustrated by numerous fully worked examples in the form of Mathcad documents that readers can use as templates for their own data, eliminating the need for programming. Intended as both a text and reference, the book assumes an elementary knowledge of calculus and probability. Graduate and advanced undergraduate students, as well as practicing engineers and scientists, will be able to use this book to solve practical problems connected with the uncertainty assessment in a wide range of engineering contexts.
