The ESIS-Technical Committee 9 on Concrete was established in 1990 and has met seven times. A proposal was put to European and extra-European laboratories entitled "Scale effects and transitional failure phenomena of reinforced concrete beams in flexure" which lead to several positive responses.

The central topic discussed by the committee was that of the minimum reinforcement in concrete members. The minimum amount of reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behaviour is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale, within which the plastic limit analysis may be applied with its static and kinematic theorems.

Carpinteri, Ferro, Bosco and El-Katieb propose a LEFM model, according to which reinforcement reactions are applied directly on the crack surfaces and a compatibility condition is locally imposed on the crack opening displacement in correspondence with the reinforcement. The theoretical model is found to provide a satisfactory estimate of the minimum percentage of reinforcement that depends on the scale and enables the element in flexure to prevent brittle failure.

Over the last several years, the four authors have jointly conducted research into the analysis of vibrating Mindlin plates as a collaborative project between Nanyang Technological University, The National University of Singapore, and The University of Queensland. The research was prompted by the fact that there is a dearth of vibration results for Mindlin plates when compared to classical thin plate solutions. To generate the vibration results, the authors have successfully employed the Ritz method for general plate shapes and boundary conditions. The Ritz method, once thought to be awkward for general plate analysis, can be automated through suitable trial functions (for displacements) that satisfy the geometric plate boundary conditions "a priori." This work has been well-received by academics and researchers, as indicated by the continual requests for the authors' papers and the Ritz software codes. This monograph is written with the view to share this so-called "p"-Ritz method for the vibration analysis of Mindlin plates and its software codes with the research community. To the authors' knowledge, the monograph contains the first published Ritz plate software codes of its kind.

Structural Studies, Repairs and Maintenance of Heritage Architecture XVII The importance of retaining the built cultural heritage cannot be overstated. Rapid development and inappropriate conservation techniques are threatening many heritage unique sites in different parts of the world. Selected papers presented at the 17th International Conference on Studies, Repairs and Maintenance of Heritage Architecture are included in this volume. They address a series of topics related to the historical aspects and the reuse of heritage buildings, as well as technical issues on the structural integrity of different types of buildings, such as those constructed with materials as varied as iron and steel, concrete, masonry, wood or earth. Restoration processes require the appropriate characterisation of those materials, the modes of construction and the structural behaviour of the building. This knowledge can be gained through a series of material characterisation techniques, preferably via non-destructive tests. Modern computer simulation can provide accurate results demonstrating the stress state of the building and possible failure mechanisms affecting its stability. Of particular importance are studies related to their dynamic and earthquake behaviour aiming to provide an assessment of the seismic vulnerability of heritage buildings. Contributions originate from scientists, architects, engineers and restoration experts from all over the world and deal with different aspects of heritage buildings, including how to formulate regulatory policies, to ensure effective ways of preserving the architectural heritage. Earthquake Resistant Engineering Structures XIII Papers presented at the 13th International Conference on Earthquake Resistant Engineering Structures form this volume and cover basic and applied research in the various fields of earthquake engineering relevant to the design of structures. Major earthquakes and associated effects such as tsunamis continue to stress the need to carry out more research on those topics. The problems will intensify as population pressure results in buildings in regions of high seismic vulnerability. A better understanding of these phenomena is required to design earthquake resistant structures and to carry out risk assessments and vulnerability studies. The problem of protecting the built environment in earthquake-prone regions involves not only the optimal design and construction of new facilities but also the upgrading and rehabilitation of existing structures including heritage buildings. The type of highly specialized retrofitting employed to protect the built heritage is an important area of research. The included papers cover such topics as Seismic hazard and tsunamis; Building performance during earthquakes; Structural vulnerability; Seismic isolation and energy dissipation; Passive earthquake protection systems.

Composite materials have been used more and more during the last decade to lighten structures. But until now, there has been no clear way of establishing how to design properly optimised laminated composite plates with no reduction in strength. Most modern references lack adequate information for the designer wanting to tailor or synthesise a design. This exciting package offers a solution. It relates the theory of composite materials to real life and provides 'rules' for designing composites structures properly and in an optimum way.
In the book, Professor Miravete demonstrates the optimisation of beams, plates and sandwich constructions in the designs of advanced composite materials. He also illustrates optimal material systems, fibre orientations and lay-up through functions of geometry, load type and boundary conditions. The associates software, on two disks, will enable
users to adapt the information to their own requirements and is very user-friendly with helpful manuals. This will be an essential package for designers and engineers in a wide range of areas, from aeronautics to automotive and
marine as well as general industry.
Chapter 1 provides a general background on composite materials.
Chapters 2, 3, 4, and 5 are concerned with constant thickness composite structures, and provide a survey of various design methodologies of shells, plates and sandwich constructions.
Chapters 6, 7, 8 and 9 examine variable thickness composite structures, and consider beams, plates and sandwiches.
A completemanual for anyone concerned with designing composite structuresIncludes book and used-friendly softwareCan be easily applied to any area - aeronautics, automotive, marine or general industry

Bridging the gap between theoretical texts and the massive and expensive software packages, this handbook covers finite element programming in a wide range of problems in mechanical, civil, aeronautical and electrical engineering. Comprehensive, it ranges from the static analysis of two- and three-dimensional structures to stress analysis of thick slabs on elastic foundations, and from two- and three- dimensional vibration analysis problems to two-dimensional field problems including heat transfer and acoustic vibrations.
The 24 printouts of powerful and valuable engineering computer programs, written in QUICK BASIC, are introduced by a preliminary chapter giving useful hints and formulae intended for structural design. The programs are capable of analysing problems in engineering design and manufacture, with text fully describing how to use the computer programs for their particular problems or tasks. The finite element method is used in all the programs, and the problems for analysis can be of quite complex design and shape and with complex boundary conditions.

In one of the greatest engineering feats of his time, Claudius Crozet led the completion of Virginia's Blue Ridge Tunnel in 1858. Two centuries later, the National Historic Civil Engineering Landmark still proudly stands, but the stories and lives of those who built it are the true lasting triumph. Irish immigrants fleeing the Great Hunger poured into America resolute for something to call their own. They would persevere through life in overcrowded shanties and years of blasting through rock to see the tunnel to completion. Prolific author Mary E. Lyons follows three Irish families in their struggle to build Crozet's famed tunnel and their American dream.

Modern society too often views water as a convenient vehicle for disposing of waste and the results are becoming increasingly apparent. Analysis of freshwater supplies frequently reveals disturbing levels of pollution, including human waste, heavy metals and synthetic chemicals, to the detriment of our health, and the health of entire ecosystems. The Water Crisis examines the roots of freshwater pollution urbanization, industrialization and intensive farming supported by case studies from the Rhine and the Great Lakes. It explores the impact of major pollutants and discusses methods of prevention. The final section provides a detailed overview of possible solutions, including soil-based treatment systems and constructed wetlands. A separate chapter is devoted to the important issue of groundwater pollution. Practical concise and accessible, this is ideal for students in environmental studies and environmental science, biology and geography, and general readers. Originally published in 1998

In the summer of 1893, at the Columbian Exposition in Chicago, an engineering marvel was unveiled and immediately captured the world's attention. It was a towering, web-like giant wheel, standing upright and rotating high above the city. Several stories taller than any existing American building, the Ferris Wheel carried adventure-seeking passengers to the dizzying height of 264 feet and provided panoramic views never before possible. George W. G. Ferris Jr. and his wheel helped usher America - eager to identify itself with ingenuity, entrepreneurialism, and innovation - into the 20th century. Yet the very wheel that came to define George Ferris in the end consumed him, leaving him ruined. This book is the first full-length biography of George Ferris. He was a civil engineer, an inventor, and a pioneer for his development of structural steel in bridge building. ""Circles in the Sky"" chronicles the life of the man responsible for creating, designing, and building the Ferris Wheel, the only structure of its time to rival the Eiffel Tower. It is, at the same time, the story of the Ferris clan, one of the nation's oldest and most fascinating families. The London Eye, erected in 1999 to welcome the new millennium, the Star of Nanchang, and most recently, the Singapore Flyer, have revived our love affair with Ferris wheels. Circles in the Sky will enchant anyone interested in engineering marvels, history, and the Ferris wheel, which reminds us that America was built by dreamers and innovators such as George W. G. Ferris Jr.
