Seismic design with supplemental energy dissipation devices
Author: Robert D Hanson/t t soong | Size: 14 MB | Format:PDF | Quality:Scanner | Publisher: EERI (Earthquake Engineering Research Institute) | Year: 2001 | pages: 135 | ISBN: 0943198135/978-0943198132
Seismic Design with Supplemental Energy Dissipation Devices imparts basic concepts of the supplemental energy dissipation technology to design engineers, architects, and building officials so they can understand its benefits and limitations in structural applications. The approach is introductory. References are cited throughout the monograph for readers who wish to study the subject in more depth. Supplemental energy dissipation systems are recent innovations to improve earthquake building performance. Research has led to a better understanding of the effects of supplemental energy dissipation on the earthquake response of buildings. Over the last 20 years, significant progress has been made in developing manufactured systems. They are being reliably designed and installed in new as well as existing buildings. Development of design codes and standards for energy dissipation systems has progressed slowly. This monograph summarizes information on their use in designing new earthquake-resistant buildings and upgrading the seismic performance of existing buildings. The following areas are covered:
* The physical consequences of adding energy dissipation systems to a structure for various types of input motion
* Summary of generic energy dissipation device characteristics
* Summary of pros and cons of specific device characteristics in meeting selected design objectives
* Seismic design limits for selecting energy dissipation systems
* Design approaches for the limits of elastic or inelastic response
About the Author
ROBERT D. HANSON received his undergraduate and master's degrees in Civil Engineering (structural engineering) from the California Institute of Technology. He is professor emeritus in the Civil Engineering Department at the University of Michigan. He was chairman of the department from 1976 to 1984. His primary research areas have been concerned with inelastic response of steel and reinforced concrete buildings, earthquake-resistant design, repair and retrofitting of buildings, pseudodynamic testing, and supplemental damping techniques. Hanson is a past president of the Earthquake Engineering Research Institute. For many years he served as the USA Technical Coordinator for the US/Japan Large-Scale Earthquake Research program for the Reinforced Concrete and Structural Steel phases. He has been a member of the NAE/NRC Committee on Earthquake Engineering, the Technical Management Committee of the Building Seismic Safety Council, the American Society of Civil Engineers, and the American Concrete Institute. He was elected to the National Academy of Engineering in 1984.
TSU T. SOONG, P.E. is Samuel P. Capen Professor of Engineering Science at the State University of New York at Buffalo, where he has been on the faculty since 1963. He earned M.S. and Ph.D. degrees in engineering sciences from Purdue University. His present teaching and research interests are large-scale systems in civil engineering, structural control and identification, reliability and safety of engineering systems, and earthquake engineering. He has served on professional committees of ATC, ASCE, and BSSC, has published extensively, has been associate editor of numerous journals, and has been co-coordinator of the NSF Research Initiative on Structural Control. He was recipient of ASCE Norman and Newmark medals in 1999 and 2002, respectively.

The purpose of the Eurocodes is to achieve harmonization between structural and geotechnical design in Europe. All of the Eurocodes are based on the same limit state philosophy that has not been widely used before for geotechnical designs. This book gives a clear and detailed demonstration of how the philosophy and principles presented in Eurocode 7 (EC7), are applied in practice. Simple language and detailed examples are used to explain the clauses in EC7, which are written in the formal and often confusing Eurocode language. The worked examples of different geotechnical designs are an important feature of this book. In particular the authors explain how Cases A, B and C are used in geotechnical designs and how characteristic and design parameters are selected. The book also outlines the most recent developments that have occurred, such as the introduction of additional design cases, as EC7 moves towards publication as a full European standard. The types of design covered include: Shallow strip and pad foundations; Pile foundations; Cantilever and embedded sheet pile retaining walls; Ground anchors; Slope stability problems; Fills. This book is an essential source of information for practising engineers involved in geotechnical designs and for engineering geologists and others involved in ground investigations and the testing of soils. It will also be a valuable text for undergraduate and postgraduate civil engineering students.
Thank you in advance

Principles of Environmental Science and Technology
Author: K. Saravanan | Size: 3.65 MB | Format:PDF | Quality:Unspecified | Publisher: New Age International Pvt Ltd Publishers | Year: 2008 | pages: 200 | ISBN: 8122415849 & 9788122415841
This book is meant to be an introductory text on the Fundamentals of Environmental Science and Engineering. Today, knowledge of Environmental Science is essential for students as well as practicing engineers and scientists of all disciplines. Here an attempt has been made to provide precise and upta date infoIlllation on the fundamental aspects of Environmental Science and Engineering without going much in-depth in to specific areas, so as to be useful for a cross section of fields of study. Indian technical universities are making the study of Environmental Science and Engineering mandatory for all courses and hence a 'comprehensive textbook covering all domains of this field (including the policy aspects and management practices) is the need of the hour.
The book adopts a simple narrative style keeping in mind both the knowledge requirements and the examination needs of university students. The authors wish to profusely thank all those who have supported them in their effort viz. the Management, the Principal, teachers, professors and students of our institution Kongu Engineering College, Perundurai, Erode. The authors also thank Mis New Age International (P) Ltd. for having accepted to publish the work and the wonderful way they have brought out this book in such a short time.

Span-Depth Ratios for One-Way Members Based on ACI 318 Deflection Limits
Author: Peter H. Bischoff and Andrew Scanlon | Size: 1 MB | Format:PDF | Quality:Original preprint | Publisher: ACI | Year: 2009 | pages: 10
Span-depth ratio (l/h) expressions are developed for steel-reinforced concrete one-way slabs and beams to satisfy deflection control and flexural strength requirements. The expressions are presented as functions of reinforcement ratio and specified deflection-to-span limit. A comparative study is performed to evaluate the effects of effective moment of inertia, shrinkage restraint, construction loads, sustained live load, long-time deflection multiplier, support conditions, and deflection limits on the resulting span-depth ratios. A comparison is also made with minimum thickness values prescribed by ACI 318 that are a function of span and support conditions only. Effects of various input parameters are considered in examples involving a simply supported rectangular beam and an interior span of a continuous one-way slab. The results of the study indicate some of the limitations associated with the ACI 318
minimum thickness requirements.
