When bridges fail, often with loss of human life, those involved may be unwilling to speak openly about the cause. Yet it is possible to learn from mistakes. The lessons gained lead to greater safety and are a source of innovation. This book contains a systematic, unprecedented overview of more than 400 bridge failures assigned to the time of their occurrence in the bridges' life cycle and to the releasing events. Primary causes are identified. Many of the cases investigated are published here for the first time and previous interpretations are shown to be incomplete or incorrect. A catalogue of rules that can help to avoid future mistakes in design analysis, planning and erection is included. A lifetime's work brilliantly compiled and courageously presented – a wealth of knowledge and experience for every structural engineer.

The comprehensive reference on the basics of structural analysis and design, now updated with the latest considerations of building technology Structural design is an essential element of the building process, yet one of the most difficult to learn. While structural engineers do the detailed consulting work for a building project, architects need to know enough structural theory and analysis to design a building. Most texts on structures for architects focus narrowly on the mathematical analysis of isolated structural components, yet Building Structures looks at the general concepts with selected computations to understand the role of the structure as a building subsystem—without the complicated mathematics. New to this edition is a complete discussion of the LRFD method of design, supplemented by the ASD method, in addition to: The fundamentals of structural analysis and design for architects A glossary, exercise problems, and a companion website and instructor's manual Material ideally suited for preparing for the ARE exam Profusely illustrated throughout with drawings and photographs, and including new case studies, Building Structures, Third Edition is perfect for nonengineers to understand and visualize structural design.

Passive and active safety systems (ABS, ESP, safety belts, airbags, etc.) represent a major advance in terms of safety in motoring. They are increasingly developed and installed in cars and are beginning to appear in twowheelers. It is clear that these systems have proven efficient, although there is no information about their actual operation by current users. The authors of this book present a state of the art on safety systems and assistance to driving and their two-wheeled counterparts. The main components constituting a driving simulator are described, followed by a classification of robotic architectures. Then, a literature review on driving simulators and two-wheeled vehicles is presented. The aim of the book is to point out the differences of perspectives between motor vehicles and motorcycles to identify relevant indicators to help in choosing the mechanical architecture of the motorcycle simulator and appropriate controls. Contents 1. Driving Simulation. 2. Architecture of Driving Simulators. 3. Dynamics of Two-Wheeled Vehicles. 4. Two-Wheeled Riding Simulator: From Design to Control.

In recent years, the systems designed to support activity in the fields of banking, health, transportation, space, aeronautics, defense, etc. have become increasingly larger and more complex. With the growing maturity of information and communication technologies, systems have been interconnected within growing networks, yielding new capabilities and services through the combination of system functionalities. This has led to a further increasing complexity that has to be managed in order to take advantage of these system integrations. The book is divided into two parts. The first part addresses the concept and practical illustrations of a “system of systems” and is a multidisciplinary introduction to the notion of a “systems of systems” that is discussed extensively in the current scientific and technical literature. After a critical comparison of the different definitions and a range of various practical illustrations, this part provides answers to key questions such as what a system of systems is and how its complexity can be mastered. The second part, described as “systems-of-systems engineering: methods and tools”, focuses on both engineering and modeling, and standardization issues that are critical to deal with the key steps in systems of systems engineering: namely eliciting stakeholder needs, architecture optimization, integration of constituent systems, qualification, and utilization.
