Links Geotechnics with Railway Track Engineering and Railway Operation
Good railway track and railway operations depend on good geotechnics, in several different ways and at varying levels.
Railway Geotechnics covers track, track substructure, load environment, materials, mechanics, design, construction, measurements, and management. Illustrated by case studies, with an emphasis on the geotechnical aspects of railway engineering, it discusses these topics from a historical perspective. It also presents the methodologies and best practices developed over the past 20 years.
Written by Four Experienced Professionals
This book:

Drystone Retaining Walls: Design, Construction and Assessment (Applied Geotechnics)
Author(s)/Editor(s): Paul F. McCombie and Jean-Claude Morel | Size: 7 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2015 | pages: 186 | ISBN: 1482250888
Take a Detailed Look at the Practice of Drystone Retaining Wall Construction
Drystone retaining walls make very efficient use of local materials, and sit comfortably in their environment. They make an important contribution to heritage and to the character of the landscape, and are loved by many people who value the skill and ingenuity that has gone into their construction, as well as simply how they look.
And yet, in engineering terms, they are complex. They can deform significantly as their loading changes and their constituent stones weather. This gives them ductility―they deal with changes by adapting to them. In some ways, they behave like conventional concrete retaining walls, but in many ways they are better. They cannot be designed or assessed correctly unless these differences are understood.
Implementing concepts that require no prior knowledge of civil engineering, the authors:
Explain the behavior of earth retaining structures
Provide a theoretical framework for modeling the mechanical stability of a drystone retaining wall
Outline reliable rules for constructing a drystone retaining wall
Include charts to support the preliminary sizing of drystone retaining walls
Examine the relevance of drystone in terms of sustainability
Describe more advanced methods of analysis
Drystone Retaining Walls: Design, Construction and Assessment draws on theoretical work and full-scale practical testing to explain how these structures work, without presuming that the reader has received an engineering education. The book goes on to give enough detail to give the professional engineer confidence in the methods used in design and assessment, and insight into what matters most in the way in which drystone retaining walls are built. It shows how to design new or replacement drystone retaining walls that are efficient, sustainable, attractive, and in keeping with the character of the area where they are built, and demonstrates how to make fair assessments of existing walls.

Inspection, Evaluation and Maintenance of Suspension Bridges Case Studies
Author(s)/Editor(s): Sreenivas Alampalli and William J. Moreau | Size: 9.6 MB | Format:PDF | Quality:Original preprint | Publisher: CRC Press | Year: 2015 | pages: 322 | ISBN: 1466596880
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.
Author(s): D. ZACCARIA, D. BIGONI, G. NOSELLI & D. MISSERONI.

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.
Author(s): D. Zaccaria, D. Bigoni, G. Noselli and D. Misseroni. | Size: 17,6 MB Format:AVI | Quality:360p | Publisher: The Royal Society | Year: 2011
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.
