Structural Shear Joints: Analyses, Properties And Design for Repeat Loading
Author: George T. Hahn, Kaushik A. Iyer, Carol A. Rubin | Size: 21,4 MB | Format:PDF | Publisher: Woodhead Publishing Limited | Year: 2005 | pages: 267 | ISBN: 0791802388
This book describes the mechanical response of butt, lap and doubler joints. The findings apply to shear connections in civil, aerospace, and other mechanical structures subjected to repeated loading. The findings are intended for engineers and NDE practitioners concerned with the design of new, as well as inspection and maintenance of existing shear joints. Fatigue strengths of the joints are derived using conventional, material S-N data and the joint stress concentration factor. Structural Shear Joints treats the different modes of load transmission: the bearing, clamped, and adhesive modes, joint geometry: fastener spacing and number of fastener rows, and fastener geometry: standard and countersunk heads and self-piercing and interference fasteners. It contains analyses that relate global features with the local conditions that govern contact fatigue damage such as the contact pressures, interface slips and the intensity and locations of stress concentrations. The role of fretting wear is discussed. The estimates of joint fatigue strength are compared with a selection of fatigue strength measurements for aluminum and steel joints. In many cases, the method offers valid estimates and preliminary designs of joints meeting given fatigue strength requirements. The book incorporates the results of over 150 recent and detailed, 2D and 3D finite element analyses of aluminum and steel connections. It includes handbook-type summaries of the results of the finite element calculations, as well as modeling details such as finite element meshes, material models, boundary conditions and validation procedures to assist design engineers with computations. A simplified methodology for modeling joints that contain adhesive is also provided. Useful for all engineers concerned with structural fatigue, the book addresses riveted and bolted joints, aluminum connections for airframes and automotive bodies, and steel connections for machines and bridges.

Author: Ernest D. Werner (editor) and Hugh P. Friedman (editor) | Size: 19.3 MB | Format:PDF | Publisher: Nova Science | Year: 2010 | pages: 417 | ISBN: 1607412586
A landslide is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability. Typically, pre-conditional factors build up specific sub-surface conditions that make the area/slope prone to failure, whereas the actual landslide often requires a trigger before being released. This book discusses such triggers, as well as their outcomes.
Research studies of landslides that have occurred in various geographical settings are also among the topics examined in this book, as well as an analysis of the factors that caused them.

The independent airport planning manual >> By A L W Bradley, UK
Author: A L W Bradley, UK | Size: 2.9 MB | Format:PDF | Publisher: Woodhead Publishing Limited | Year: September 2010 | pages: 180 | ISBN: ISBN 1 84569 713 8 ISBN-13: 978 1 84569 713 6
- provides airport planners and architects with an essential guide and reference tool, based on the author’s extensive experience
- discusses key airport planning issues including forecasting demand, planning and strategic objectives and airport security
- outlines important airport planning principles specified by IATA for masterplan development featuring evaluation techniques and independent development planning
- focuses on the design of the terminal pier and satellite infrastructure with particular reference to effective passenger segregation and baggage handling system design concepts
This independent manual provides airport planners and architects with an essential guide and reference tool, based on the author’s extensive experience in the field and involvement in developing best practice airline and airport industry guidelines.
Chapter 1 discusses the key issues airport planners need to take account of, including forecasting demand, planning and strategic objectives, physical site constraints, airport security and the characteristics of terminals, satellites and piers. Chapter 1 also discusses cargo and aircraft maintenance facilities, general airfield infrastructure, landscaping and access provision. Chapter 2 refers to the outline development planning principles specified by IATA for masterplan development. Masterplan evaluation techniques are also explored and the author’s own approach to independent development planning is explained, setting the context for the chapters that follow.
Chapter 3 focuses on the design of the terminal pier and satellite infrastructure, particularly in the context of effective passenger segregation. This chapter also discusses and explains the various airside and landside retail models and shows how to obtain optimized landside and airside retail income. Chapter 4 reviews baggage handling system design concepts, referencing the three categories of baggage handling system and the technologies that support them. The pros and cons of different hold baggage screening locations and technologies are explored, including next generation baggage handling systems. Chapter 5 covers apron design, including such features as passenger airbridges and Multi-Aircraft Ramping Systems (MARS) for aircraft parking. The needs of both low-cost and legacy carriers are explored. Chapter 6 focuses on airport security, discussing potential threats to aircraft and airports, including the potential impact of explosives on airport infrastructure. The chapter also explains best practice for improving security in terminals, piers, satellites, car parks and forecourts as well as the airport perimeter. The final chapter comprises a series of airport case-studies, including airports processing predominantly low-cost and those processing predominantly legacy carriers. The case studies provide the designer with real examples of processes and layouts within airports.
