This report documents and presents the results of developing a Chemical Mixture Tool (CMT) for the study of Assessing Soil and Groundwater Impacts of Chemical Mixture Releases from
Hazardous Materials Transportation Incidents sponsored by the Transportation Research Board (TRB) of the US National Academies. The study was developed by HSA Engineers & Scientists
(HSA) (a member of the Conestoga Rovers & Associates (CRA) family of companies). It is a preliminary tool intended to estimate, assess, classify, predict, and quickly communicate the
various fate and transport characteristics of chemical mixtures released into the subsurface as a result of hazardous materials transportation incidents. The tool is intended to enable carriers, shippers, responders, risk compliance specialists, and regulators to predict and assess the potential environmental concerns, risks, and hazards to soil and groundwater posed by chemical
mixtures.

  Dynamic Plasticity
Posted by: kowheng - 03-25-2011, 08:45 AM - Forum: Structural Dynamics and Earthquake Engineering - Replies (1)

Dynamic Plasticity

[Image: 45711492373815109436.jpg]

[Image: info.png]
Title: Dynamic Plasticity
Author: N.Cristescu.pdf
Publisher:World Scientific Publishing
Year: 2007
Pages: 481 with bookmark
Type: PDF 5.79 MB
ISBN-13: 9789812567475
ISBN-10: 981256747X

The present book is not simply a new addition of the book Dynamic Plasticity, initially published in 1967, a long time ago. Certainly this edition is not only a new version, containing the essential of the old book and what has been done meantime. Why again Dynamic Plasticity? Well because very many books published meantime on the subject are not mentioning the waves which are to be considered in Dynamic Plasticity. Also, generally, the plastic waves are slower than the elastic one. Thus, when considering a simple problem of propagation of waves in thin bars, for any loading at the end, the plastic waves are reached by the elastic ones, and will not propagate any more. Only a part of the bar is deforming plastically. Examples of this kind are very few.
I thought that this new version is too restrictive for the today students which know little of static plasticity, differential equations, dynamic elastic–plastic properties, etc. Therefore, I thought to write a simpler book, containing the main concepts of dynamic plasticity, but also something else. Thus I thought that this new version would contain the elementary concepts of static plasticity, etc., which would be useful to give. Also it would be good to give other problems, not directly related to dynamic plasticity. Thus I started with some classical problems on static plasticity, but only the simplest things, so that the readers would afterwards understand also the dynamic problems. Also, since in dynamic problems the soils and rocks played a fundamental role, I thought to write a chapter on rocks and soils.
Then were expressed several chapters about dynamic plasticity, as propagation of elastic–plastic waves in thin bars, the rate influence and the propagation of waves in Flexible strings. It is good to remember here that all problems related to dynamic problems, are to be considered using the mechanics of the wave propagation; without the wave propagation mechanics all results concerning constitutive equations, rate effect, etc. are only informative. Such problems are mentioned however in the book. We have presented mainly the different aspects on constitutive equations of materials, as resulting from dynamic problems. Rate effects are considered in this way. They have been used by a variety of authors. The same with the mechanics of Flexible strings, presented afterwards. Not very many authors have considered till now the mechanics of deformable cables.
Therefore I thought to write a very simple book, which can be read by the students themselves, without any additional help. They can understand what “plasticity” is after all. Then several other problems have been presented. Not trying to remove the fundamentals, I have thought also to add some additional problems, which are in fact dynamic, though the inertia effect is disregarded. They are the stationary problems, quite often met in many applications. It is question obviously, about problems involving Bingham bodies, as wire drawing, floating with working plug, extrusion, stability of natural inclined plane, etc. Further I have considered various problems of plastic waves, using various theories. Also the perforation problems, was presented, using various symmetry assumptions, or any other assumption made. The last chapter is on hypervelocity impact. To keep it simple, I have given only very few information about. Thus I wished to show what hypervelocity is and how is it considered now.
Though the book is a very simple one, I wished to ask any author to disregard possible missing of some papers. All literature is certainly incomplete. One has done today much more than given here. It was impossible for me to mention “all” authors in this field.

  Tilt-up Concrete Buildings: Design and Construction Guide
Posted by: ir_71 - 03-25-2011, 08:03 AM - Forum: Concrete - Replies (1)

Tilt-up Concrete Buildings: Design and Construction Guide

Size: 4.4 MB | Format: PDF | Publisher: BCA | Year: 1998 | pages: 148 | ISBN: 0721015336

[Image: 07476646990723769630.jpg]


[Image: info.png]

This publication brings together worldwide experience of tilt-up into a single document in a form suitable for the UK. The examples and details shown are selected to demonstrate the versality of tilt-up and to provide the necessary information for its wider adoption in the UK. Where necessary, additional original work has been undertaken to ensure compatibility with UK codes and practice. The contents will appeal to all those involved with the procurement of new low-rise buildings – from clients and their advisors through to contractors. In particular, Chapter 2 gives all parties a nontechnical overview of the technique including applications, benefits, costs, architectural opportunities, historical development and typical applications examined through real case studies. It also includes a summary of detailed cost modelling showing that tilt-up can be highly competitive in many sectors in the UK. The efficiency of tilt-up results from careful planning and close co-operation between designers and constructors, who should both carefully study Chapter 3.
Chapter 4 describes the design and construction of floor slabs and foundations, and Chapters 5 to 12 provide information on all aspects of the design, construction and erection of tilt-up panels. These chapters are intended for both designers and constructors, to impart a common understanding of their roles. However, Chapter 5 contains considerable detailed technical material on the structural analysis and design of tilt-up panels, mostly of use to the structural engineer. Chapter 13 provides additional information on suppliers of goods and services. Finally, it is worth emphasising that, although this publication deals mainly with on-site tilt-up, much of the material is equally relevant to factory-cast panels, which may prove more suitable for a particular project.

  POST-TENSIONED CONCRETE FLOORS IN MULTI-STOREY BUILDINGS
Posted by: ir_71 - 03-25-2011, 07:48 AM - Forum: Journals, Papers and Presentations - Replies (4)

POST-TENSIONED CONCRETE FLOORS IN MULTI-STOREY BUILDINGS

Size: 2.2 MB | Format: PDF | Publisher: BCA | Year: 1994 | pages: 23

[Image: 69259216260352799621.jpg]


[Image: info.png]

This publication aims to de-mystify the techniques of posttensioned concrete floor construction in multi-storey buildings, w h i l s t l o o k i n g a t t h e e c o n o m i c s a n d practicability of construction. It is intended for two broad categories of reader. Firstly, it presents an introduction to the benefits, constraints, principles and techniques for non-technical professionals. These people will wish to understand the broad issues of an essentially simple technique with which they may not be entirely familiar, without being swamped by equations. Sections 1 and 3 provide the briefest executive overview, whilst reading Sections 1 to 4 plus 7 will give a broader picture. Secondly, it can be used as a more technical review for those who, in addition to the above issues, wish to explore further the principles of design and construction. In this case all sections should prove useful. This publication is not intended to be a full technical reference book for design, but it does address many of the issues often omitted from such works.
