Vibration Control of Active Structures: An Introduction

Vibration Control of Active Structures: An Introduction
A. Preumont,
Springer
2002
ISBN: 1402004966
385 pages
PDF 12,1 MB
This text is an introduction to the dynamics of active structures and to the feedback control of lightly damped flexible structures; the emphasis is placed on basic issues and simple control strategies that work. This book consists of 14 chapters. Chapters 2 and 3 are devoted to the dynamics of active structures; the open loop transfer functions are derived from the constitutive equations; the discussion includes active trusses with piezoelectric struts, and beams and shells with embedded laminar piezoelectric actuators and sensors. Chapters 4 and 5 discuss the virtues of collocated actuator/sensor configurations and how they can be exploited to develop active damping with guaranteed stability. Chapter 6 addresses vibration isolation for one and 6 d.o.f.. Chapter 7 discusses optimal control for SISO systems with symmetric root locus. Chapter 8 discusses the design tradeoffs for SISO systems in the frequency domain, including the Bode amplitude/phase relationship. Chapter 9 provides a more general discussion of optimal control using of optimal control using the Riccati equation; spillover is examined. Chapters 10 and 11 review briefly the concepts of controllability, observability and stability. Chapter 12 discusses the semi-active control, including some materials on magneto-rheological fluids. Chapter 13 describes various practical applications to active damping, precision positioning and vibroacoustics, and chapter 14 discusses the active damping of cable- structures. This book is intended for structural engineers who want to acquire some background in vibration control; it can be used as a textbook for a graduate course on vibration control or active structures. The text is supplemented with 113 problems; a solutions manual is available through the publisher to teachers using this book as a textbook.

David V. Chadderton "Building Services Engineering, 4th Edition"
Published by Spon Press | Publication date : May 2004 | ISBN: 0415315352 | PDF | 399 pages | English | 6.9 MB
The fully revised fourth edition of this well-established textbook takes into account recent changes to codes and technology and includes two new key chapters on acoustic design and HVAC control strategy, as well as an expansion of the chapter on air conditioning. The design of building services and the many calculations involved are fully explained, and features include: introductions, learning objectives, key terms and concepts, worked examples and questions to aid understanding, reinforce learning and provide assignments.
Lecturers can also use questions for written examinations. The subjects of heating, air conditioning, water and gas distribution, electricity and drainage are all covered at introductory level and beyond. The use of information technology in the design and use of buildings is introduced and actively encouraged.
David Chadderton is a Chartered Professional Engineer with the Institution of Engineers Australia, a Chartered Building Services Engineer with the Engineering Council in the UK, through the Chartered Institution of Building Services Engineers, and a Member of the Australian Institute of Refrigeration, Air Conditioning and Heating. Since November 2001, David has been director of his own company, Eteq Pty Ltd. specializing in the designing and implementation of energy saving projects in commercial, healthcare, university and manufacturing buildings.

It's common lately have a lot of posts requesting another sharing site, caused by servers restrictions, censorship in some countries, etc.
I'd like to know if the example above is useful and viable in any country/user and try to practice this. Beyond this reason, using a dedicate multi-site to share, force the user to download the file and upload it again. Of course, naturally will be verified if the link is OK and if the software/book/material is OK too!
I know there's a lot of posts that you copy/paste a link from another site. It's OK! But we can start with new ones.
Another important think: Sometimes is useful CHANGE THE NAME of the file to upload, cause some companies uses a search engine inside share-sides to try to find illegal (pirate) software. So. changing the name, double compressing (with keyword) and changing the size (putting a extra file during compressing), it's possible to turn better the possibilities that the file does not be removed!

PLUMBING-HEATING-COOLING-CONTRACTORS-NATIONAL ASSOCIATION
Scope:
The development of a recommended code of plumbing practice, design, and installation, including the establishment of performance criteria predicated on the need for protection of health and safety through proper design, installation, and maintenance of plumbing systems. This scope excludes the development of specific standards related to the composition, dimensions, and/or mechanical and physical properties of materials, fixtures, devices, and equipment used or installed in plumbing systems.
Purpose:
To provide practices and performance criteria for the protection of health and safety through proper design of plumbing systems.
Exceptions:
In case of practical difficulty, unnecessary hardship or new developments, exceptions to the literal requirements may be granted by the authority having jurisdiction to permit the use of other devices or methods, but only when it is clearly evident that equivalent protection is thereby secured.

This document is intended to provide owners and practicing engineers with current “best practices” to reduce the likelihood of progressive collapse of buildings in the event of abnormal loading. The report includes a discussion of an acceptable risk approach to progressive collapse, which involves defining the threat, event control, and structural design to resist postulated event. Practical means for reducing risk for new and existing buildings are presented. An extensive review is provided of the design methods used to enhance a buildings resistance to progressive collapse. These include the indirect method (providing sufficient tie forces), the specific local resistance method (designing key elements to withstand abnormal loads), and the alternate load path method (allowing for redistribution of load in the event of the loss of a key member). Design considerations for different structural materials are summarized. The methodology for evaluating and mitigating progressive collapse potential in existing buildings is also discussed.
