Concrete folded plate roofs used to cover large open expanses of space can pose complex design problems soluble only through detailed mathematical analysis. This book introduces the engineer to practical schemes and practicalities, and goes on to provide multitudes of useful design tables, which allow linear interpolation, for a large range of various schemes of folded plate roofs to help the engineer with his designs. Design examples using both SI and USA (British Imperial) units are provided using these tables.

The great cathedrals and churches of the medieval West continue to awe. How were they built, and why do they remain standing? What did their builders know about what they were doing? These questions have given rise to considerable controversy, which is fully reflected in the papers selected here. The first section of the book is concerned with the medieval builders and their design methods; the second focuses on engineering issues in the context of the infamous collapse of the choir at Beauvais in 1284. The following papers extend the analysis into the 15th century, looking for example at Brunelleschi's dome for Florence Cathedral, and deal with the often neglected structures of roofs, towers and spires.

The application of a new production philosophy, leading to "lean production" (using less space, less human effort, less product development time etc), is expected to change almost every industry and bring about radical changes in the organization of work. This text examines this process.

Reflecting current techniques and practical experience of continued deterioration of reinforced concrete structures, this revised and updated edition brings together the fundamental aspects of this worldwide problem, and offers advice on how investigations, diagnosis and consequent remedial work should be carried out. It covers reinforced concrete buildings, water-retaining and water-excluding structures, marine structures and bridges. The nine chapters also cover deterioration and renovation of concrete floors, repair and waterproofing of concrete roofs. The deterioration of concrete liquid retaining structures, including sewers, caused by chemical attack is also discussed and suggestions made for remedial work. The author discusses the newer methods of cathodic protection, realkalization and desalination to inhibit corrosion of reinforcement in existing structures.

Although first published nearly thirty years ago, this book remains up-to-date, intellectually stimulating and realistic. Unlike most texts in the field, it relates design closely to the science and mathematics that are students' chief concern, and shows their relevance. It shows how to make simple but illuminating calculations, and how to achieve the insight and the invention that often result from them. Covering design principles in depth, this is, and remains, an original book: although some of the ideas which were novel in 1971 are now widely accepted, others remain new.

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

The reader will learn how to implement new models and algorithms in a robust, efficient manner. A large number of numerical examples are included, all fully equipped with code and data so that the reader can reproduce the results and use them as a starting point for their own work. Like the original textbook, this book will prove invaluable for researchers, professionals and advanced students using reservoir simulation methods. This title is available as Open Access on Cambridge Core.

This volume contains the lectures presented at the NATO ADVANCED STUDY INSTITUTE that took place at Newark, Delaware, U. S. A. , July 14-23, 1985. The objective of this meeting was to present and discuss selected topics associated with transport phenomena in porous media. By their very nature, porous media and phenomena of transport of extensive quantities that take place in them, are very complex. The solid matrix may be rigid, or deformable (elastically, or following some other constitutive relation), the void space may be occupied by one or more fluid phases. Each fluid phase may be composed of more than one component, with the various components capable of interacting among themselves and/or with the solid matrix. The transport process may be isothermal or non-isothermal, with or without phase changes. Porous medium domains in which extensive quantities, such as mass of a fluid phase, component of a fluid phase, or heat of the porous medium as a whole, are being transported occur in the practice in a variety of disciplines.

Entre Meeanique et Arehiteeture: e'est-a-dire, entre les proeedes teehniques qui, depuis des temps immemoriaux eonforment l'art et la scienee de la eonstruetion au developpement de la scienee physique et mathematique la plus generale et, peut-etre, la plus abstraite, subalternata tanturn geometriae et philosophiae naturalis, eomme le disait Tartaglia, bien que liee aux faits les plus farniliers: la statique et la meeanique des mareriaux et des struetures. Le theme qui nous eoneeme est done la relation entre la technique et la scienee dans son exemple le plus important, je crois, du point de vue historiographique mais aussi epistemologique: a savoir, la relation entre le savoir faire, qui se eonforme a la norme, en respeetant une determination et une eongruenee parfaites avee son objectif, et la theorie, qui eonfirme la norme et temoigne la neeessite de la determiner eongrfiment avec les lois de la nature. Avee une extreme perspieaeite, quelque peu offusquee par une frivolite erudite, l' Abbe Franeeseo Maria Franeesehinis, mathematieien et adepte de la philosophie des lurnieres, se peneha sur la question dans un bref traite qu'il publia a Padoue en 1808 sous 1 le titre Des Mathematiques appliquees , soutenant la nouvelle tendanee didaetique introduite a l'Universite de Padoue par l'ephemere Regne d'Italie. Simulant un eonflit entre plusieurs auteurs, Franeesehinis exposait une premiere these dans un Discours inaugural qu'il reeita peut-etre reellement en 1807, lorsqu'il devint titulaire de la Chaire de Mathematiques appliquees.

It will help to stimulate co-operative research efforts among investigators in the USA and China and other countries.

This work provides comprehensive guidance on maintaining old waterfront walls, especially gravity walls constructed with stone masonry, brick blocks or mass concrete. It should be of use to engineers and owners responsible for such structure. Many existing waterfront structures (harbour and dock walls, breakwaters, seawalls, flood defences, skin walls, bridge piers and abutments) are crucial parts of industrial or environmental facilities. Many date back to the 19th century and earlier, and information on their design and construction is often incomplete. They are often massive structures, and the problems of working over or under water and on the buried back of the wall mean that they are difficult and expensive to investigate and maintain, yet they represent substantial capital assets and appropriate management and maintenance are essential. This work draws together a wealth of information and experience on the types of wall that were constructed up to the earlier part of this century. It includes numerous drawings and illustrations of these walls and reviews their performance. It goes on to identify and describe the most suitable techniques available for their inspection, struct

The developments of the late 1990s in the structural analysis of aluminium components are presented with particular reference to work in Europe. This text brings together European experts who are actively engaged in the formulation of design rules and in the writing of codes of practice. The text is written against a background of the British Standard on the structural use of aluminium, BSB8118; the development of an equivalent Eurocode; and the noticeable increase in research on the performance of aluminium structural components leading to useful advances in analysis and design philosophies. The book opens with a chapter on loading, safety and design principles and includes a discussion of fatigue and fracture. This is followed by a series of chapters on particular components such as beams, beam columns and plate girders which highlight advances in research. The problem of welded aluminium joints is discussed in depth, as are the design rules for bolted joints. Each chapter gives the background to design rules giving designers the confidence to follow progressive ideas and to support these by accurate and perceptive structural analysis.
