Report: Seismic analysis of cantilever retaining walls, Phase I
Author: Green Russell; Ebeling Robert | Size: 4.6 MB | Format:PDF | Year: 2002 | pages: 104
This report summarizes the results of the first phase of a research investigation examining the seismic loads induced on the stem of a cantilever retaining wall. The computer program FLAC (Fast Lagrangian Analysis of Continua) was used to perform nonlinear dynamic analyses on a cantilever retaining wall designed by the U.S. Army Corps of Engineers static design criteria. The procedures used to determine the various numerical model parameters are outlined and the results of the FLAC analyses presented, in which preliminary trends are identified.

Concise and easy to read, this reference presents key information on how to approach quality assurance for construction projects. Containing quick reference tables and a wealth of figures, the book presents valuable quality related data and guidelines. It provides coverage that spans from the inception of a project through issuance of a completion certificate. Go the extra distance and become the consummate professional: Learn about different types of contract deliverable systems Explore important points to be considered while developing detail design and shop drawing Plan for major activities during construction process Create design review checklists Anticipate costs involved with quality
Understand reasons why an executed work may be rejected Develop ways to assess your quality efforts In addition to covering standard procedures and concepts, the author introduces and discusses a wide range of-the-state-of-the-art-tools and approaches that professionals can use to develop an Integrated Quality Management System most suitable for their specific project. These include Six Sigma, TRIZ, and Total Quality Management, as well ISO 9000, ISO 14000 Environmental Management System, and OHSAS 18000 This information will also prove valuable for cutting-edge instructors who wish to provide engineering/management students with in-depth knowledge about current practices and familiarize...

Design of Lightweight Footbridges for Human Induced Vibrations
Author: Christoph Heinemeyer, Christiane Butz, Andreas Keil and other | Size: 1.6 MB | Format:PDF | Publisher: JRC – ECCS | Year: 2009 | pages: 98 | ISBN: 9789279133879
This report is a part of activities for the maintenance, further harmonisation, further development and promotion of the Eurocodes. It has been prepared in a field where so far no unified design rules applicable across different materials and ways of construction exists in the Eurocodes, namely in the field of limiting human induced vibrations of foot bridges.
It is a contribution to the evolution of EN´s 1990 and 1991 and may also be used together with some specific rules in EN 1995-2 that apply to timber bridges as a source of support to
- further harmonize design rules across different materials, and
- further develop the Eurocodes.
The rules for the “Design of lightweight footbridges for human induced vibrations” given in this report are the result of projects funded by the Research Fund for Coal and Steel (RFCS), initiated and carried out by a group of experts from RWTH Aachen, Germany, Arcelor Mittal Luxembourg, TNO, The Netherlands, SCI, United Kingdom, CTICM, France, FEUP Porto, Portugal and Schlaich, Bergermann und Partner, Stuttgart, Germany.
The agreement of RFCS and of the project partners to publish this report in the series of the “JRC-Scientific and Technical Reports” in support of the further development of the Eurocodes is highly appreciated.
The examples given in this guideline are mainly from light-weight steel structures, where the consideration of human induced vibrations is part of the optimization strategy of the structure. Therefore the publication has been carried out in the context of the JRC-ECCS-cooperation agreement in order to support the further harmonisation of National procedures and the further evolution of the Eurocodes.

Air blast loaded structures do not only fail by the arrival of first the pressure wave. In addition, the negative part of the pressure wave and the oscillations of the structure could be a reason for the failure.
The displacement of large plane structures like windows or other kind of fa¸cades is reduced after the impact of the pressure wave by the material damping and by the damping due to the air. The influence of the air damping is investigated here using analytical, numerical and experimental approaches.

Dear friends,
I am in need for this paper:
Clough, G. W., and Duncan, J. M. 1971. "Finite Element Analyses of Retaining Wall Behavior," Journal of the Soil Mechanics and Foundations Division, American Society of Civil Engineers, Vol 97, No. SM12, Proceedings Paper No. 8583, pp 1657-1673.
This Book is written for Project Managers and Engineers, for Sales Managers and Project Planners, for Top Executives and Managers of the Legal Department of a company as from the client's as also from the contractor's side. Finally it is for students of the mentioned disciplines in their endeavour to become a leader in their respective fields and not to reproduce mistakes that others have made before them. This book does not try to give legal advice, but it tries to help engineers and project managers how to solve difficult contract situations. Contract disagreements between the main parties in international projects evolving into conflicts seem to occur more often nowadays than before. This trend does not only damage the project in question but it also discredits the engineering and contracting industry with a number of negative consequences. The purpose of this handbook is to describe and analyze how disagreements and minor conflicts that are quite normal between the main contract players, should be handled. In major construction projects small conflicts can easily develop into important conflicts causing delays, overruns and insufficient quality. We give advice on how to avoid conflicts and how to solve them in order to mitigate the losses! All parties involved have this responsibility for the sake of their own results, for the sake of the reputation of the project industry and for the sake of their company. The book might help the parties to avoid or solve future conflicts earlier, thereby saving money for their projects, their companies and their society. This book consists of 10 chapters including the introduction to the subject and conclusions with our recommendations. Finally the book includes a glossary with an explanation of the main concepts and a list of literature. The content of the chapters are based on real project and conflict experiences collected by the three authors.
