Despite the killing of Osama bin Laden, the Al-Qaeda network he inspired is still alive and well and in some places, thriving. The rise and persistence of the radical threat must be viewed through a fusion of psychology, sociology, and organization development and human behavior theory. Breaking Al-Qaeda Psychological and Operational Techniques, Second Edition serves to educate those on the front line, as well as strategic planners and thinkers on the subject. Focusing on the background and history of Al-Qaeda, developments in recent years, and how and where Al Qaeda is spreading, it examines the current state of the terrorist network and what the organization and individual cells are doing to recruit, plan, and carry out attacks against the West. The book also investigates intelligence and counterterror methods to garner information on Al Qaeda and steps that are being taken to counter the continuing threat. The author explores recent developments related to the Arab spring, and addresses how the Al-Qaeda network continues to expand especially in Egypt, Yemen, Somalia, Mali, and Syria.Illustrating the shifting message and ideology of Al-Qaeda since the death of Osama bin Laden, the text describes how regional and international governments can utilize intelligence and apply counterterror measures to break relationships between groups.

Understand the impact of fatigue on high strength steel joints with this comprehensive overview High strength steels are highly sought after for industrial and engineering applications ranging from armored vehicles to welded engineering components built to withstand considerable stress. The mechanical properties of welded joints made from high strength steel are integrally linked to the specific welding process, which can have an enormous impact on fatigue performance. Welded High Strength Steel Structures: Welding Effects and Fatigue Performance provides a comprehensive analysis of high strength steel joints and the ramifications of the welding process. It guides readers through the process of performing thermal analysis of high strength steel structures and evaluate fatigue performance in the face of residual stress. The result is a volume with innumerable use cases in engineering and manufacture. Welded High Strength Steel Structures readers will also find: An author with decades of experience in research and engineering Numerous studies of various classes of high strength steel joints Studies on tubular structures for welding residual stress Welded High Strength Steel Structures is a must-own for welding specialists, materials scientists, mechanical engineers, and researchers or industry professionals in related fields.

This book is the companion volume to Design of High Strength Steel Reinforced Concrete Columns - A Eurocode 4 Approach. This book provides a large number of worked examples for the design of high strength steel reinforced concrete (SRC) columns. It is based on the Eurocode 4 approach, but goes beyond this to give much needed guidance on the narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete. Special considerations are given to resistance calculations that maximize the full strength of the materials, with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. These examples build on the design principles set out in the companion volume, allowing the readers to practice and understand the EC4 methodology easily. Structural engineers and designers who are familiar with basic EC4 design should find these design examples particularly helpful, whilst engineering undergraduate and graduate students who are studying composite steel concrete design and construction should easily gain further understanding from working through the worked examples which are set out in a step-by-step clearly fashion.

This book is the companion volume to Design Examples for High Strength Steel Reinforced Concrete Columns - A Eurocode 4 Approach. Guidance is much needed on the design of high strength steel reinforced concrete (SRC) columns beyond the remit of Eurocode 4. Given the much narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete, there is a clear need for design beyond the guidelines. This book looks at the design of SRC columns using high strength concrete, high strength structural steel and high strength reinforcing steel materials - columns with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. The companion volume provides detailed worked examples on use of these high strength materials. This book is written primarily for structural engineers and designers who are familiar with basic EC4 design, and should also be useful to civil engineering undergraduate and graduate students who are studying composite steel concrete design and construction. Equations for design resistances are presented clearly so that they can be easily programmed into design spreadsheets for ease of use.

Completely revised and updated, this fourth edition of Structural Steelwork: Design to Limit State Theory describes the design theory and code requirements for common structures, connections, elements, and frames. It provides a comprehensive introduction to structural steelwork design with detailed explanations of the principles underlying steel design.

See what’s in the Fourth Edition:

All chapters updated and rearranged to comply with Eurocode 3

Compliant with the other Eurocodes

Coverage of both UK and Singapore National Annexes

Illustrated with fully worked examples and practice problems

The fourth edition of an established and popular text, the book provides guidance for students of structural and civil engineering and is also sufficiently informative for practising engineers and architects who need an introduction to the Eurocodes.
