Author(s)/Editor(s): Cheng, Franklin Y. Truman, Kevin Z | Size: 15 MB | Format:PDF | Quality:Unspecified | Publisher: Spon Press | Year: 2010 | pages: 725 | ISBN: 9781315274874, 9780203089651, 0203089650, 9781628708134, 1628708131
Today's biggest structural engineering challenge is to design better structures, and a key issue is the need to take an integrated approach which balances control of costs with the requirement for handling earthquakes and other dynamic forces.
Structural optimization is based on rigorous mathematical formulation and requires computation algorithms for sizing structural elements and synthesizing systems. Now that the right software and enough computing power are readily available, professionals can develop a suite of alternative designs and a select suitable one.
A thoroughly-written and practical book on structural optimization is long overdue. This solid book comprehensively presents current optimization strategies, illustrated with sufficient examples of the design of elements and systems, and presenting descriptions of the process and results. Emphasis is given to dynamic loading, in particular to seismic forces.
Practising engineers and researchers and will find this book an excellent reference, and advanced undergraduates or graduate students can use it as a resource for structural optimization design.
Abstract: Structural optimization is based on rigorous mathematical formulation and requires computation algorithms for sizing structural elements and synthesizing systems. This book comprehensively presents optimization strategies, illustrated with examples of the design of elements and systems and presenting descriptions of the process and results.

Safe mobility is clearly linked to transport sustainability, as fatalities and injuries resulting from people engaged with transport networks increasingly becomes a public health concern, relative to other health threats. This volume presents the current state of the knowledge across a multitude of analytical and context specific transport safety areas. It includes a comprehensive set of chapters authored by many of the world's leading experts in both behavioural and engineering aspects of safety mobility.
The book increases the level of knowledge on road safety contexts, issues and challenges; shares what can currently be done to address the variety of issues; and points to what needs to be done to make further gains in road safety.

This book presents an innovative new approach to studying source mechanisms of earthquakes, combining theory and observation in a unified methodology, with a key focus on the mechanics governing fault failures. It explains source mechanisms by building from fundamental concepts such as the equations of elasticity theory to more advanced problems including dislocation theory, kinematic models and fracture dynamics. The theory is presented first in student-friendly form using consistent notation throughout, and with full, detailed mathematical derivations that enable students to follow each step. Later chapters explain the widely-used practical modelling methods for source mechanism determination, linking clearly to the theoretical foundations, and highlighting the processing of digital seismological data. Providing a unique balance between application techniques and theory, this is an ideal guide for graduate students and researchers in seismology, tectonophysics, geodynamics and geomechanics, and a valuable practical resource for professionals working in seismic hazard assessment and seismic engineering.

I was wondering what the practice is in other countries regarding the architectural and structural layout of residental buildings.
What are your general structural systems in terms of lateral stability and/or seismic design - wall, frame or dual? Do you encounter a lot vertical irregularities that are forced due to (bad) architectural planning?
To keep it simple I had in mind buildings up to some 6-7 floors above ground in moderate to high seismic regions.
In Croatia the most common structural layout are wall systems, very often with lots vertical irregularities. The use of frame structures is very rare.
I would say there are two types of residental buildings: pure residental and residental buildings with the ground floor reserved for some retail/caffe's/restaurants.
In terms of seismic design the second one is in general the most problematic one, as the structural systems in general always border with soft storey due to different occupancies in the ground floor and the other floors. As such, the walls on the above floors are in lots of cases some deep beam-like members with questionable behaviour in earthquake scenarios.
One of the most common problems is alot of randomly placed RC walls in the above floors on the borders between two apartments, which is in alot of cases the architects choice because of sound insulation.
There's also the addition of basement floors mainly reserved for garages and parking space which introduces additional difference in layouts resulting in most cases in transfer structuras or some hybrid systems (part regular + part transfer).
So, please share your expiriences regarding architectural and structural solutions, and the problems you encounter.

Based on the results, I think RAM SS is better than ETABS and STAAD PRO as far as design of concrete or steel building system is concerned.

The Proceedings of the NATO Advanced Study Institute on Analysis and Design of Bridges held at ~e§me, lzmir, Turkey from 28 June 1982 to 9 July 1982 are contained in the present volume. The Advanced Study Institute was attended by 37 lecturers and participants from 10 different countries. The Organizing Committee consisted of Professors P. Gtilkan, A. C. Scordelis, S. T. Wasti and 9. Yl. lmaz. The guidelines set by NATO for the Advanced Study Institute require it to serve not only as an efficient forum for the dissemination of available advanced knowledge to a selected group of qualified people but also as a platform for the exploration of future research possibilities in the scientific or engineering areas concerned. The main topics covered by the present Advanced Study Institute were the mathematical modelling of bridges for better analysis and the scientific assessment of bridge behaviour for the introduction of improved design procedures. It has been our observation that as a result of the range and depth of the lectures presented and the many informal discussions that took place, ideas became fissile, the stimulus never flagged and many gaps in the engineering knowledge of the participants were "bridged". Here we particularly wish to mention that valuable informal presenta tions of research work were made during the course of the Institute by Drs. Friedrich, Karaesmen, Lamas and Parker.

This book is an attempt to present systematically the general theory of dynamic stability of elastic systems and its numerous applications. Investigations of the author are used as the basis for the book, part of which was published previously in the form of separate articles. The author's method of presentation is retained where the problems treated have been analyzed by other authors.
The book is devoted to the solution of engineering problems. As in every other engineering (or physics) investigation, the presentation consists of first choosing an initial scheme or pattern, and then using the approximate mathematical methods to obtain readily understood results. This intent, and the desire to make the book easily understood by a large number of readers, is reflected in the arrangement and structure of the book. The book consists of three parts.
PART I is concerned with the simplest problems of dynamic stability which do not require complicated mathematical methods for their solutions. By using these problems, the author wishes to acquaint the reader with previously investigated problems. At the same time, certain peculiarities of the phenomena of instability, which previously have been only sketchily mentioned, are clarified. PART I also contains methods of solution of the general problem.
PART II begins with two chapters containing the minimum necessary mathematical information; a conversant reader can disregard these chapters. The properties of the general equations of dynamic stability are then examined; methods are presented for the determination of the boundaries of the regions of instability and the amplitudes of parametrically excited vibrations for the general case.
PART III is concerned with applications. Various problems of the dynamic instability of straight rods, arches, beams, statically indeterminate rod systems, plates, and shells are examined. The choice of examples was dictated by the desire to illustrate the general methods and present solutions to practical problems. The number of examples was limited by the size of the book.
