This document lists visual strength grades, species and sources of timber, and specifies the strength classes
from EN 338, to which they are assigned.
NOTE For the grades, species and sources included, there is long experience of use and/or satisfactory test data.
The sources listed are therefore largely determined by existing commercial practice.

This guide to sustainable design of low-rise domestic buildings presents BRE’s expertise on the performance of building materials and fabric in a single compact volume.
It gives building professionals the starting points for selection and specification of structural elements, materials and finishes. All aspects of building design are covered: site investigation and preparation, foundations, walls, windows and doors, roofs, floors and ceilings, basements, building services plus much more.
Fully in line with UK regulations and standards, the guide is based on key sustainable design requirements, in particular, how to achieve a long life, limit maintenance requirements, reduce defects and design for the future.
Designing quality buildings brings together the expertise of BRE’s most experienced architects, engineers, surveyors and scientists and is based on a thorough understanding of the physical, chemical and environmental characteristics of building materials and fabric.
360pp, 173 line drawings, 78 photos.

CONTENTS
Tools for Seismic Structural Analysis
Basic Modelling Concepts
Linear Static Analysis
Linear Dynamic Modal Response Spectrum Analysis
Linear Dynamic Modal Response History Analysis
Linear Dynamic Explicit Response History Analysis
Nonlinear Static Pushover Analysis
Nonlinear Dynamic Response History Analysis
Incremental Nonlinear Dynamic Analysis (IDA)
IDA is a relatively new approach in which a structure is repeatedly
analyzed for each motion scaled for gradually increasing/decreasing
intensities.
Probabilistic Approaches (e.g. FEMA 350) quantifying
Dynamic Time History Analysis
In general, a three-dimensional model is necessary for TH
Analysis. However, due to limitations in available software,
3-D inelastic time history analysis may not be practical
(except for very special and important structures).
Main Concerns in Nonlinear Dynamic Analysis:
Modelling of hysteretic behaviour
Modelling inherent damping
Selection and scaling of ground motions
Interpretation of results
Results may be quite sensitive to seemingly minor
pert rbations
perturbations
Due to the fact that some of these concerns may be
insurmountable in the framework of a deterministic analysis,
a probabilistic framework is being developed.

Water Resources Development in Developing Countries
Water Resources Development in Developing Countries
Author(s): Elsevier Science
Publisher: Elsevier Science
Date: 1991 Format: PDF
Language: English
ISBN10: 0444889566
Pages: 290
Size: 9.00 MB
Book Description
Water resources exploitation has been regarded as a way of initiating economic development in many countries. Planning concepts are now changing. Thorough environmental studies, sociological and economic studies now preceed project formulation. Justification solely on the basis of benefit cost studies is no longer sufficient for many development agencies. The broader approach is introduced in this book, but the real emphasis is on the situation in and needs of developing countries.

Groundwater Pollution: Theory, Methodology, Modelling, and Practical Rules
Author: Jean J. Fried | Size: 17.43 MB | Format:PDF | Quality:Original preprint | Publisher: Elsevier Science Ltd | Year: November 1975 | pages: 330 | ISBN: 0444413162, ISBN-13: 978-0444413161
Pollution has become the ever-increasing monster that threatens our civilization (what is left of it, at least), the Moloch that will eat us. This is what the information media say, and perhaps they are right; now again perhaps they are wrong, or at least too pessimistic. We feel that the real danger is not pollution but the ignorance of pollution problems. This book built around the example of groundwater pollution, is an attempt to rationalize and to quantify the problem and to show that the danger of pollution should not be despised, of course, but conversely, it should not be exaggerated.

This British Standard gives guidance on durability, required and predicted service life and design life of buildings and their components and/or parts. It applies primarily to new buildings and their components and/or parts rather than to alterations and repairs. It also gives guidance on presenting information on the service and design life of buildings and their components and/or parts when a detailed brief is being developed.
This British Standard applies to civil engineering projects involving buildings, but only partially to other civil engineering projects such as roads, bridges and dams.
This British Standard does not deal with many aspects of obsolescence, i.e. when buildings or parts of buildings are replaced or altered either to suit different needs and changing conditions including change of use, mandatory requirements or when new products offer better performance without a corresponding increase in cost. It should also be borne in mind that a decision to replace or alter obsolete buildings or their parts may be influenced
by a reassessment of their predicted service lives.
NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover.
NOTE 2 The numbers in square brackets in the text of this standard refer to the numbered references in Appendix D.

Dictionary of Waste & Water Management
Author: Paul G. Smith, John S. Scott | Size: 4.9 MB | Format:PDF | Publisher: BUTTERWORTH HEINEMANN | Year: 2002 | pages: 448 | ISBN: 0750646381
Water and waste management covers the design, building and operation of plants for water treatment and supply, sewerage, wastewater treatment and disposal, and solid waste treatment and disposal. Since the last edition in 2002 there has been an increasing importance on the issues reflecting climate change. This is particularly important when the result of this change must be `managed? and `controlled? to maintain an amenity such as water supply. This new edition includes many new entries on the topics of stormwater management and flood management, as well as the new EU Directives that cover this field. With over 7000 terms, this dictionary encompasses the most recent terminology on water and waste management. It is a handy reference for consultants, contractors and professional engineers as well as academics and students who need a quick definition to technical terms.
Audience:
Civil, environmental and chemical engineering professionals. Environmental biologists, environmental chemists and environmental managers.
