Concrete Admixtures Handbook; Properties, Science and Technology
Since the publication of the first edition, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding 10 chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures.
The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the First Edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful.
Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.

Acronis True Image remains one of the most user-friendly and powerful applications in its class. Unlike most other disk-image utilities, you can perform all the tasks without exiting Windows. However, if your system can't boot, Acronis True Image can be launched from a CD or a disk. A scheduler and an incremental method (saving only sectors changed since the last backup) minimize the fuss of backing up your system so you can perform it every day. Another great feature, Secure Storage, lets you make images inaccessible from Windows so they can't be damaged. The program works at a decent speed, 1GB in five minutes, and doesn't considerably affect system speed. Acronis True Image supports all features necessary to a home user: compression, password protection, the ability to split an image into several volumes, and the ability to move your system to another hard drive. This new version offers an option that lets you specify which files and folders you'd like to archive. You can browse images as if they were usual hard drives and extract only necessary files. The program's wizard-based instructive interface suits inexperienced users. Acronis True Image doesn't offer professional features, such as installing an image on multiple PCs at once, but we consider it a must-have for home users who want to safeguard their systems.
Features and Benefits:
1-Backup:
Disk imaging
File backups
Full, incremental and differential backups
Around the clock protection
3-Recover:
Quick restore
Recover files and folders
Recover to any point in the past
Keep working during a restore

Author: Helmut Wenzel and Dieter Pichler
Publisher: Wiley (June 17, 2005)
Hardcover: 308 pages
Language: English
ISBN-10: 0470024305
ISBN-13: 978-0470024300
Description:
The development of methods for the monitoring and assessment of structures has been driven by the demand for better as well as cheaper methods. Constraints like undisturbed traffic flow, limited access possibilities and finally limited or even shrinking budgets have led to a development of an assessment model well fitted to the construction sector.
Ambient vibration monitoring, which provides the opportunity to obtain useful data under ambient conditions for the assessment of structures and components, is the backbone of structural assessment monitoring and control. Nevertheless there is little available on this subject for the practising engineer. This book enables the practising engineer to learn about this fascinating area and gain information on practical applications.
Ambient Vibration Monitoring describes current ambient vibration methodologies along with direct information on applicable solutions, and includes:
* Years of pioneering practical research collated into one book.
* Real-world applications with practical solutions.
This book will be of interest to all engineers engaged in structural assessment monitoring and control, and provides a useful tool for students of structural dynamics, civil engineering, mechanical engineering and related fields.

Title: Port Designer's Handbook - Recommendations and Guidelines
Author: Carl A. Thores
ISBM-10: 0727732285
ISBN-13: 978-0727732286
Description:
Over the past twenty years there has been considerable improvement and new information in the design of port and berth structures. This handbook reflects the latest progress and developments in navigation safety, port planning and site selection, layout of container, oil and gas terminals, cargo handling, berth design and construction, fender and mooring principles. It presents guidelines and recommendations for the main items and assumptions in the layout, design and construction of modern port structures, and the forces and loadings acting on them. The book provides an evaluation of different designs and construction methods for port and berth structures, and recommendations given by the different international harbor standards and recommendations. Practicing harbor and port engineers and students will find the handbook an invaluable source of information.

For FloorLL of 2.4 kPa on square floor slab panel, the maximum load delivered to beams is w(span)/2 = 2.4(6)/2 = 7.2 kN/m. Which means the area load distribution to frame elements are correct.
But in the member force diagrams for frames, the maximum load delivered is 7.2(2) = 14.4 kN/m.
[/b]
In ETABS v9.7 member force diagrams for frames, the maximum load delivered is 6.911 kN/m. There is a difference of 0.289 kN/m with respect to 7.2 kN/m, but this will not affect the results.
Therefore, by comparing the results of SAP2000 v14.2 to the results of ETABS v9.7, the bending moment, shear, and deflection has been doubled in SAP2000.

Hi All
I am looking for strengthening of RC beams by adding steel plates both in flexure and shear.
If any one of you has any material / articles / design procedures for this please upload.
Thanks in advance

The work presented in the publication Metal Fatigue Damage—Mechanism, Detection, Avoidance, and Repair was sponsored by the ASTM-ASME Joint Committee on the Effect of Temperature on the Properties of Metals and financed by The Metal Properties Council. The Applied Research Panel under the Chairmanship of M. Semchyshen and the Gas Turbine Panel Chaired by G. J. Wile, cooperated in this project. Mr. S. S. Manson, who headed the Task Group under the Applied Research Panel, was responsible for the coordination of the papers presented in this publication.
!!!As all literature on the metal preliminary-strained (prestressing) spatial designs interests. Excuse for language. Thanks.

Understanding and controlling vibration is critical for reducing noise, improving work environments and product quality, and increasing the useful life of industrial machinery and other mechanical systems. Computer-based modeling and analytical tools provide fast, accurate, and efficient means of designing and controlling a system for improved vibratory and, subsequently, acoustic performance. Computer Techniques in Vibration provides an overview as well as a detailed account and application of the various tools and techniques available for modeling and simulating vibrations. Drawn from the immensely popular Vibration and Shock Handbook, each expertly crafted chapter of this book includes convenient summary windows, tables, graphs, and lists to provide ready access to the important concepts and results. Working systematically from general principles to specific applications, the coverage spans from numerical techniques, modeling, and software tools to analysis of flexibly supported multibody systems, finite element applications, vibration signal analysis, fast Fourier transform (FFT), and wavelet techniques and applications. MATLAB® toolboxes and other widely available software packages feature prominently in the discussion, accompanied by numerous examples, sample outputs, and a case study. Instead of wading through heavy volumes or software manuals for the techniques you need, find a ready collection of eminently practical tools in Computer Techniques in Vibration.
