The Loma Prieta earthquake struck the San Francisco area on October 17, 1989, causing the loss of 63 lives and $10 billion of damage. As the results of the research, conducted in response to the earthquake, became known over the following three years, the U.S. Geological Survey, the sponsor of much of the research, approached the National Research Council (NRC) about how the results of the Loma Prieta earthquake research could be applied to other earthquake-prone areas of the country.
This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine.

FRESH AND HARDENED PROPERTIES OF SELF-CONSOLIDATING FIBER REINFORCED CONCRETE
Author: Hemant B. Dhonde, Y.L. Mo, Thomas T.C. Hsu and John Vogel | Size: 7.8 MB | Format:PDF | Publisher: ACI MATERIALS JOURNAL | Year: 2007 | pages: 40
When steel fibers are added to concrete mix, the tensile and shear resistance of the
traditional fiber reinforced concrete are known to be enhanced. However, fibers are also known
to impede workability of plain concrete. To improve the workability, Self-Consolidating Fiber
Reinforced Concrete (SCFRC) mixes were developed in this study for application in prestressed
concrete beams. Extensive fresh and hardened properties of traditional fiber reinforced concrete
and SCFRC mixes produced using two different types and variable amounts of hooked steel
fibers are presented in this paper. The SCFRC mixes demonstrated satisfactory workability and
stability up to a fiber-factor of 55. In general, SCFRC mixes proved to have greater normalized
tensile strength than the traditional fibrous concrete mixes for the same fiber-factor. The
optimum fiber content was found to be governed by workability requirements of the concrete
mix.
Keywords: steel fiber reinforced concrete, self-consolidating concrete, self-consolidating fiber
reinforced concrete, fresh properties, workability, hardened properties.

World Wind lets you zoom from satellite altitude into any place on Earth.
NASA thanks Sun Microsystems for their support in the development of World Wind Java. This generous support has led to the very artful and exemplary use of the Java OpenGL API. The possibilities for portable, high-performance 3D graphics rendering are now wide open

This practical text is an essential source of information for those wanting to know how to deal with the variability that exists in every engineering situation. Using typical engineering data, it presents the basic statistical methods that are relevant, in simple numerical terms. In addition, statistical terminology is translated into basic English.
In the past, a lack of communication between engineers and statisticians, coupled with poor practical skills in quality management and statistical engineering, was damaging to products and to the economy. The disastrous consequence of setting tight tolerances without regard to the statistical aspect of process data is demonstrated.
This book offers a solution, bridging the gap between statistical science and engineering technology to ensure that the engineers of today are better equipped to serve the manufacturing industry.
Inside, you will find coverage on:
* the nature of variability, describing the use of formulae to pin down sources of variation;
* engineering design, research and development
, demonstrating the methods that help prevent costly mistakes in the early stages of a new product;
* production, discussing the use of control charts, and;
* management and training, including directing and controlling the quality function.
The Engineering section of the index identifies the role of engineering technology in the service of industrial quality management. The Statistics section identifies points in the text where statistical terminology is used in an explanatory context.
Engineers working on the design and manufacturing of new products find this book invaluable as it develops a statistical method by which they can anticipate and resolve quality problems before launching into production. This book appeals to students in all areas of engineering and also managers concerned with the quality of manufactured products.
Academic engineers can use this text to teach their students basic practical skills in quality management and statistical engineering, without getting involved in the complex mathematical theory of probability on which statistical science is dependent.

Seismic Design of Cast-in-Place Concrete Diaphragms, Chords, and Collectors : A Guide for Practicing Engineers
Author: Moehle, Jack P., Hooper, John D., Kelly, Dominic J., and Meyer, Thomas R. | Size: 1.8 MB | Format:PDF | Publisher: NIST | Year: 2010 | pages: 33 | ISBN: none
Building structures generally comprise a three-dimensional framework of structural elements configured to support gravity and lateral loads. Although the complete three-dimensional system acts integrally to resist loads, we commonly conceive of the seismic force-resisting system as being composed of vertical elements, horizontal elements, and the foundation (Figure 1-1). The vertical elements extend between the foundation and the elevated levels, providing a continuous load path to transmit gravity and seismic forces from the upper levels to the foundation. The horizontal elements typically consist of diaphragms, including collectors. Diaphragms transmit inertial forces from the floor system to the vertical elements of the seismic force-resisting system. They also tie the vertical elements together and thereby stabilize and transmit forces among these elements as may be required during earthquake shaking. Diaphragms are thus an essential part of the seismic force-resisting system and require design attention by the structural engineer to ensure the structural system performs adequately during earthquake shaking.
