The Direct Analysis Method: Bridging the Gap from Linear Elastic Analysis to Advanced Analysis in Steel Frame Design
Author: Andrea E. Surovek and Ronald D. Ziemian | Size: 181 KB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2005 | pages: 11
Developments in analytical software and computer hardware over the past few
decades provide engineers with powerful tools for more realistically considering the
behavior of steel structures. More sophisticated methods of analysis offer significant
advantages in steel frame design by eliminating the need to calculate effective length
factors and more directly including factors that affect system and member strength .
One such method, the Direct Analysis approach, accounts for the effects of member
inelasticity and frame imperfections in the assessment of both member and system
strength. The latter is achieved by directly including these effects in calculating the
distribution of forces in the structural system. This approach is applicable for use in
the design office using commercially available software and it is applicable to a wide
variety of structural problems including braced frames, moment frames and mixed
systems. Just as importantly, the approach it allows for a natural transition between
current elastic analysis procedures and the future availability of second-order inelastic
analysis programs suitable for use with an advanced analysis-design approach.

Jean-Marc Franssen - Paulo Vila Real
Fire Design of Steel Structures: Eurocode 1: Actions on structures; Part 1-2: General actions - Actions on structures exposed to fire; Eurocode 3: EN 1991-2: General rules - Structural fire design
This book explains and illustrates the rules that are given in the Eurocode for designing steel structures subjected to fire. After the first introductory chapter, Chapter 2 explains how to calculate the mechanical actions (loads) in the fire situation based on the information given in EN 1990 and EN 1991.
Chapter 3 presents the models to be used to represent the thermal action created by the fire.
Chapter 4 describes the procedures to be used to calculate the temperature of the steelwork from the temperature of the compartment and Chapter 5 shows how the information given in EN 1993-1-2 is used to determine the loan bearing capacity of the steel structure.
The methods use to evaluate the fire resistance of bolted and welded connections are described in Chapter 7.
Chapter 8 describes a computer program called "Elefir-EN" which is based on the simple calculation model given in the Eurocode and allows designers to quickly and accurately calculate the performance of steel components in the fire situation.
Chapter 9 looks at the issues that a designer may be faced with when assessing the fire resistance of a complete building. This is done via a case study and addresses most of the concepts presented in the earlier Chapters.
The concepts and fire engineering procedures given in the Eurocodes may see complex those more familiar with the prescriptive approach. This publication sets out the design process in a logical manner giving practical and helpful advice and easy to follow worked examples that will allow designer to exploit the benefits of this new approach to fire design.

Fracture and fatigue of welded joints and structures
Author: Edited by Kenneth A. Macdonald | Size: 5.8 MB | Format:PDF | Quality:Original preprint | Publisher: Woodhead Publishing Limited | Year: 2011 | pages: 334 | ISBN: ISBN 978-1-84569-513-2
The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyzes the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimized in the design process.
Part 1 concentrates on analyzing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part 2, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modeling residual stresses in predicting the service life of structures.

Author: A V Pogorelov | Size: 3.3 MB | Format:PDF | Quality:Unspecified | Publisher: American Mathematical Society | Year: 1988 | pages: 82 | ISBN: 9780821845257
This book contains an accessible exposition of the geometric theory of stability of elastic shells, starting from the basic facts of the theory of finite and infinitesimal bendings of surfaces. The author has included a number of new results obtained in recent years. In particular, the complete solution of the problem of stability of spherical shells under an external pressure is contained here without any assumptions regarding the character of buckling. Within the framework of the mathematical model of the phenomenon, the author gives a complete investigation of the loss of stability of a general, strictly convex shell fastened along an edge under external pressure. The author considers the question of the loss of stability of cylindrical shells under axial compression and the effect of various factors on the critical load, among other questions. In contrast to the author's 1967 book on the subject, this work is limited to a relatively small number of classical problems on the loss of stability of shells, but these problems are investigated more thoroughly.

Composites offer great promise as light and strong materials whose uses are no longer confined to high performance structures. Their major advantages, which are true for almost all composites, are increased stiffness with respect to homogeneous materials and in increased strength to crack extension. However, their application is still limited by the lack of complete knowledge about their strength under different load conditions and the prediction of the damage evolution and the way cracks develop in these materials is still an important topic of research. This book contains recent developments and results in composite materials science, including contributions from well-known researchers in this specialist field. Both polymeric and metal matrix composites are included and investigated with experimental, analytical and numerical analyses.

Author: C H Scholz | Size: 67 MB | Format:PDF | Quality:Unspecified | Publisher: Cambridge University Press | Year: 2002 | pages: 504 | ISBN: 9780521655408
Our understanding of earthquakes and faulting processes has developed significantly since publication of the successful first edition of this book in 1990. This revised edition has therefore been thoroughly up-dated whilst maintaining and developing the major themes of the first edition. Graduate students and research scientists in the fields of seismology, physics, geology, geodesy and rock mechanics will benefit greatly from this book, which provides a unifying framework within which a wide range of faulting phenomena can be interpreted
