An Introduction to Seismic Isolation

Editorial Reviews
Book Description
These authors present much sought after information on the design procedures for seismically isolated structures. Using a logical progression, they describe seismic isolation along with the concepts of earthquake structural dynamics underlying the isolation theory. Methods discussed will provide the basis for continuing development and refinement.

From the Publisher
These authors present much sought after information on the design procedures for seismically isolated structures.

Methods discussed will provide the basis for continuing development and refinement.
-------------
Skinner et al. book on seismic isolation is much more than an introduction, is a must to anyone interested on the subjects of seismic isolation and passive energy dissipation. The book is quite complete, and it is easy to read (if you do not mind NZ English), both for students or experienced professionals or professors. All chapters have basic and advanced material. The book is not married with a single base isolation system, a difference with other books available on this topic. I am looking forward to a second edition of this book that may add some new material on the development of other isolation devices and design methods that have been proposed during the last seven years.
------------------------
Written by the precursors of modern seismic isolation technology, "An Introduction to seismic isolation" is one of the most challenging treatments in structural dynamics so far. Skinner et al first introduce the reader to the concept of seismic isolation as a whole, explaining the philosophy behind this technique, followed by a brief review of the structural dynamics theory needed for the basic understanding of the more specifically mathematical explanations in chapter 4, where the equations of motion for the theoretical models are explicitly derived. Here, the authors make the difference, providing a good treatment in which a high mathematical understanding level is required. Chapter 3 is a complete description of the different seismic isolation systems available, describing their controlling parameters, composition, tested performance and analytical models for design. Chapter 5 is an excellent guide for analysis and design, from a more practical point of view. Chapter 6 is simply a description of some of the more prominent seismic isolation projects worldwide. Until now, the best reference, sophisticated yet understandable bibliography about seismic isolation.

  Statistics for Environmental Engineers - by Linfield C. Brown, Paul Mac Berthouex
Posted by: lisine - 06-01-2012, 01:54 PM - Forum: Environmental Engineering - Replies (2)

Statistics for Environmental Engineers - 2nd Edition

Author: Linfield C. Brown, Paul Mac Berthouex | Size: 7.55 MB | Format: PDF | Quality: Original preprint | Publisher: CRC Press | Year: January 29, 2002 | pages: 512 | ISBN: 1566705924, ISBN-13: 978-1566705929

[Image: info.png]
Two critical questions arise when one is confronted with a new problem that involves the collection and analysis of data. How will the use of statistics help solve this problem? Which techniques should be used? Statistics for Environmental Engineers, Second Edition helps environmental science and engineering students answer these questions when the goal is to understand and design systems for environmental protection. The second edition of this bestseller is a solutions-oriented text that encourages students to view statistics as a problem-solving tool.

Written in an easy-to-understand style, Statistics for Environmental Engineers, Second Edition consists of 54 short, "stand-alone" chapters. All chapters address a particular environmental problem or statistical technique and are written in a manner that permits each chapter to be studied independently and in any order. Chapters are organized around specific case studies, beginning with brief discussions of the appropriate methodologies, followed by analysis of the case study examples, and ending with comments on the strengths and weaknesses of the approaches.

  ASCE - Establishing Confidence in Surface Wave Determined Soil Profiles
Posted by: melkat - 06-01-2012, 11:32 AM - Forum: Journals, Papers and Presentations - No Replies

Establishing Confidence in Surface Wave Determined Soil Profiles

Author: P. Michaels | Size: 1 MB | Format: PDF | Quality: Unspecified | Publisher: GeoRisk 2011 | Year: 2011 | pages: 837 - 844


[Image: info.png]

Surface waves can be used to determine the shear velocity profile from the ground surface to some depth limited by the spectral band of the seismic source. A number of factors influence the uncertainties of the determined profile. The field acquisition factors include the deployment geometry of geophones, the spectral characteristics of the geophones, recording instruments, and seismic source. A key data processing factor is the determination of a dispersion curve from the field recordings. Finally, there are important choices in conducting the inversion of the dispersion curve \vhich leads to the final soil profile. Even if the field factors and acquired data are fixed, determination of the dispersion and the inversion decisions will have a strong influence on the final result. Different engineers will make different decisions, and a range of soil profiles can be expected. Assessment of this variability was the goal of the Surface Wave Benchmark Study sponsored by the Geophysical Engineering Committee of ASCE. Participants were invited to analyze as little or as much of the data as they wished. This paper documents one participant's analysis of a selected set of the data taken at a single location. A key finding documents how a lack of low frequency content limits the maximum depth for which one can have confidence in the soil profile.

  ASCE - Improving MASW Results for a Site w Through the Use of Highith Shallow Bedrock
Posted by: melkat - 06-01-2012, 11:23 AM - Forum: Journals, Papers and Presentations - No Replies

Improving MASW Results for a Site with Shallow Bedrock through the Use of Higher‐Mode Data

Author: Daniel et al | Size: 1.23 MB | Format: PDF | Quality: Unspecified | Publisher: GeoFlorida 2010: Advances in Analysis, Modeling & Design | Year: 2010 | pages: 1360 - 1368


[Image: info.png]

In a case where the active-source multi-channel analysis of surface waves method was applied to a site consisting of clay residuum overlying basalt bedrock, inversion for the undamental-mode Rayleigh wave results in shear-wave velocities for the rock that are much lower than expected values. preliminary results from multi-mode inversions incorporating data from the 1st and 2nd higher-order modes provide more realistic velocities within the bedrock than could be obtained using the fundamental-mode data alone. However, the model data fit shows much room for improvement. Acquiring, processing and interpreting multi-mode data poses some challenges that need further research.
