Product Description:
For buildings and factories located near railway or subway lines, the vibrations caused by the moving trains, especially at high speeds, may be annoying to the residents or detrimental to the high-precision production lines. However, there is a lack of simple and efficient tools for dealing with the kind of environmental vibrations, concerning simulation of the radiation of infinite boundaries; irregularities in soils, buildings and wave barriers; and dynamic properties of the moving vehicles. This book is intended to fill such a gap.
Compared with the boundary element method (BEM) for solving the half-space problems, the finite/infinite element method (FIEM) presented in this book has the following advantages:
* It requires less effort in formulation and computation.
* It can be directly incorporated in an existing FEM analysis program.
* It is capable of simulating the irregularities in buildings, soils and tunnels.
* It can be used to evaluate the efficiency of various wave barriers for vibration reduction.
The methodology presented in the book can be adopted to analyze the vibrations caused by road traffic as well.

After the Earth Quakes: Elastic Rebound on an Urban Planet

Book Description:
Earthquakes rank among the most terrifying natural disasters faced by mankind. Out of a clear blue sky-or worse, a jet black one-comes shaking strong enough to hurl furniture across the room, human bodies out of bed, and entire houses off of their foundations. When the dust settles, the immediate aftermath of an earthquake in an urbanized society can be profound. Phone and water supplies can be disrupted for days, fires erupt, and even a small number of overpass collapses can snarl traffic for months. However, when one examines the collective responses of developed societies to major earthquake disasters in recent historic times, a somewhat surprising theme emerges: not only determination, but resilience; not only resilience, but acceptance; not only acceptance, but astonishingly, humor. Elastic rebound is one of the most basic tenets of modern earthquake science, the term that scientists use to describe the build-up and release of energy along faults. It is also the best metaphor for societal responses to major earthquakes in recent historic times. After The Earth Quakes focuses on this theme, using a number of pivotal and intriguing historic earthquakes as illustration. The book concludes with a consideration of projected future losses on an increasingly urbanized planet, including the near-certainty that a future earthquake will someday claim over a million lives. This grim prediction impels us to take steps to mitigate earthquake risk, the innately human capacity for rebound notwithstanding.

Avoiding Claims in Building Design: Risk Management in Practice
Avoiding Claims in Building Design: Risk Management in Practice
By Malcolm Taylor
Publisher: Wiley-Blackwell
Number Of Pages: 304
Publication Date: 2000-06-15
ISBN-10 / ASIN: 0632053267
ISBN-13 / EAN: 9780632053261
The chance of being claimed against is now a major risk factor for every building designer, engineer, quantity surveyor and project manager. Apart from the cases that go to court, many other claims are settled before they reach that stage. The cost of insurance to meet claims is now a substantial component of every practice’s overheads. Sensible risk management can identify the potential sources of claims, reduce their likelihood, warn of impending trouble and control how the claim is to be defended.
This book explains how to plan a risk management strategy and suggests techniques that can supplement the practice’s existing management procedures without imposing unnecessary bureaucracy. It attaches as much importance to the interaction of risk between members of the design team as to the risk profile of the practice itself.
The first part defines risk and its origins, discusses how risk can arise in the various professions and types of practice, and how it interacts between the professions, compares quality assurance with risk management, and advises on the relations between the practice, its insurers and its lawyers. It concludes with advice on how to create a risk strategy and system for the office.
The second part is devoted to techniques and covers: setting up the appointment; creation of the team; managing the project; the risks of CDM; the complications of procurement; and drafting, awarding and administering the building contract. Risk implications of the major contract forms are discussed in detail. It concludes with advice on the handling of claims.
The book contains references to a number of legal cases to illustrate the risks discussed. It is recommended reading not only for the individual professions (architect, engineer, QS, project manger), but for all of them collectively in understanding how the risk of one profession can become the risk of any of his fellow team members.

Dynamic and Mobile GIS: Investigating Changes in Space and Time
Dynamic and Mobile GIS: Investigating Changes in Space and Time
CRC | November 10, 2006 | ISBN 0849390923 | PDF | 310 pages | 10.6MB
With the widespread use of PDAs, wireless internet, Internet-based GIS, and 3G and 4G telecommunications, the technology supporting mobile GIS is rapidly gaining popularity and effectiveness. Dynamic and Mobile GIS: Investigating Changes in Space and Time addresses Web GIS, mobile GIS, and the modeling, processing, and representation of dynamic events, as well as current demands to update GIS representations.
Providing a comprehensive overview of this emerging technology, this book highlights innovations, new ways of modeling both spatial objects and dynamic processes affecting them, and advances in visualization. Featuring contributions from established GIS workers, it begins with an introduction of extant technology and previews future developments. The book examines challenges to security and privacy and presents practical solutions to these problems while focusing on modeling approaches and exploring the need to display an appropriate level of information in a mobile environment. Concluding with a study of mobility, the book also contains practical examples of applications of mobile devices for disaster management and environmental monitoring.
Dynamic and Mobile GIS: Investigating Changes in Space and Time offers detailed cases of successful applications and identifies the current cutting-edge aspects of mobile and dynamic GIS. The book also looks to the future, investigating important research directions and potential challenges.

This book is the outcome of eleven years of continuous effort (1974-1985). Late in 1973, some members of Technical Committee 8 (Stability) of the ECCS (at that time chaired by Dr. D. SFINTTSCO), decided to create a Technical Working Group called PLATE BUCKLING, in order to promote knowledge in the field of steel plated structures as used 1n structural engineering. One main original aim was the development of research work in the general field of stiffened and unstiffened plate elements, enabling the preparation of a set of European Design Recommendations covering problems in plate and box girders. The language used in all documents and discussions had to be exclusively English, for obvious reasons of economy. The basic format adopted was. that of limit states. This decision was greatly influenced by the four big accidents which had occured, between 1969 and 1971, to box girder bridges in the process of erection and by all the subsequent enquiries and studies.
