BS 9250:2007 provides guidance on methods that can be used to meet the “well sealed ceiling” requirements for cold and warm pitched roofs.
Applicable to architects, house builders, and building control officers it outlines robust design details for the construction of more airtight ceilings and for the control of air movement into pitched roofs.
BS 9250 provides guidance for dwellings and domestic buildings on the selection of materials, design principles, construction methods and design details covering: the junction of walls and ceilings; junctions of ceiling materials; penetration through ceilings (e.g. pipes, outlets, cables, light fittings, loft hatches, tubular rooflights and roof windows). It also includes cold and warm roof applications and will apply to new, and the refurbishment of existing, buildings.

Guide for the Design and Construction of Fiber-Reinforced Concrete Structures
Size: 0.6 MB | Format:PDF | Publisher: CNR – Advisory Committee on Technical Recommendations for Construction | Year: 2007 | pages: 57
This document contributes to the series published over the last few years by the Italian CNR
(National Research Council) relating to the structural use of composite materials, with the first
volume being the Instructions n. 200 in 2004. The documents published so far have dealt with the
following: plating of reinforced and prestressed concrete as well as masonry structures through the
use of long fibers reinforced composite materials (FRP) (CNR-DT 200/2004), plating of timber
structures (CNR-DT 201/2005) as well as metallic ones (CNR-DT 202/2005) and finally, the use of
FRP bars as reinforcement of concrete structures (CNR-DT 203/2006).
The subject of this document is the structural use of a completely different composite material:
Fiber Reinforced Concrete (FRC). It does not have a polymeric matrix like a Fiber Reinforced
Polymer (FRP) but a cementitious matrix to which short fibers are added. They can be made of
steel, polymeric materials as well as inorganic materials such as carbon, glass and natural materials.
Furthermore, an ordinary steel reinforcement as well as reinforcing prestressed bars can also be
present. The adding of fibers to concrete gives a significant residual strength after cracking. This
property depends on many factors, including the aspect ratio (corresponding to the
length/equivalent diameter of the fibers), the volumetric percentage of the fibers as well as their
physical and mechanical properties.
FRC structures have become gradually more widespread worldwide over the last few years. This
has consequently led to the drawing up of technical guidelines becoming necessary.

Green Building A to Z - Understanding the Language of Green Building
Author: Jerry Yudelson | Size: 2.1 MB | Format:PDF | Publisher: New Society Publishers | Year: 2007 | pages: 240 | ISBN: 978-0865715721
Editorial Reviews
Product Description
Green building is the fastest-growing trend to hit since the Internet, bringing with it an enormous range of new products, systems, and technologies. Green Building A to Z is an informative, technically accurate, and highly visual guide to green building, for both decision-makers and interested citizens. It begins with an introduction to the importance of green buildings and a brief history of the green building movement, outlines the benefits and costs of green buildings, and shows how you can influence the spread of green buildings. The book touches on key issues, such as enhancing water conservation, reducing energy use, and creating a conservation economy.
The book examines all aspects of green buildings, including:
Architecture 2030
Locally sourced materials
Natural ventilation
Solar energy
Zero-net-energy buildings
More than just a reference, this book emphasizes the importance of green buildings and green developments for a sustainable future. It will be an invaluable resource for businesspeople, homeowners, product manufacturers, developers, building industry professionals, and government officials.
Jerry Yudelson is a professional engineer with an MBA. He has trained three thousand people in the LEED (Leadership in Energy and Environmental Design) Green Building Rating System, and has chaired Greenbuild, the world’s largest green building conference, for the past four years. The founder of a green building consulting firm, he is the author of three books on green building marketing and an advisor to manufacturers, venture capital firms, design firms, and developers.

Product Description
Concrete and stone seem made to last forever. But the fact is they develop structural damage over time. While not always as dramatic as the collapse of a roof section at the Paris Charles de Gaulle airport in 2004, gradual changes also occur that may compromise a building's appearance and structure. These changes include efflorescence, thermal stress, material incompatibilities, corrosion, and impact. Failed Stone systematically analyzes cases of damage in contemporary international architecture and offers strategies for minimizing the risk of damage. Examples include such high-visibility structures as Finlandia Hall in Helsinki by Alvar Aalto, Renzo Piano's Parco della Musica in Rome, and the National Museum of the American Indian in Washington. In nine chapters, typical kinds of damage are explained and illustrated with real-world examples.
About the Author
Patrick Loughran is an architect and engineer and has worked as a façade designer in Chicago since 1994. His book Falling Glass: Problems and Solutions in Contemporary Architecture analyzes damage and defects of glass facades and was also published by Birkhäuser.

Dear Admin
after the wide jump for our forum to be the best forum in the world , and all of us saw the improvement touched every thing
so , my suggestion come as the following
1. change this section name from ( suggestions ) to ( suggestions & complains )
2. appointment a referee from the best moderators be responsible about this section
3. the referee responsibilities , to review the warnings from moderators & check applieng rules by the right way & receive the complains from members and the final decision will be from him
this suggestion because the moderators have a heavy tasks and they are not angels or prophets and the human mistaks will be done
so , all of us keep in his mind that we are engineers and we are in a civil forum
regards
Make any renovation job go smoother. Building renovation, conservation and reuse represents more than half of all construction work - and is projected to increase to 80% by 2004. Structural Renovation of Buildings, by Alexander Newman, puts a single, convenient source of information about all aspects of structural renovation and strengthening of buildings at your fingertips. While its focus is largely on low and midrise buildings, you can apply the principles it clarifies to buildings of any size - steel-framed, masonry, or wood. Whether you're repairing deteriorated concrete...rehabilitating slabs on grade...strengthening lateral-load resisting systems...renovating a building facade...handling seismic upgrades or fire damage, you'll find this time-and-trouble-saving guide loaded with practical tips, methods, and design examples. It's also heavily illustrated with autoCAD generated details, supplier illustrations of materials, procedural techniques, and much, much more.

Many thanks to uploader and the member who is willing to share this book! I'm willing to award a member who make download link(s) to this book with 500 points - so here is some kind of motivation. (Award goes only for the whole book in PDF format)
Nowadays and due to the utmost develpmnet that happened for electronic Books...
We can get tons of books and papers... millions of equations ...
Thanks god because these books are availbel....
But I hope the world have to change the methods of teaching....
We loss the basics and fundamentals with this huge informations...
We need to the mothers of books which provide us the basic knowledge and the way to think and creat a better life....
I look to the genius scientest Issac Newtons how he wrote a science in a simple rules
Force=massx accel. ...It is a simple and general rule...because he is genius
Same issue for Albert Inestian..Maxewll...
I look to civil engineering knowledge ... If I open any book for example dyanamic of structure... Any reader can find many thousand of complex equations ...spending a lot of time to know and the basic concepts hidden within tons of equations....
No thinking, No basics and Fundamentals, Just reading code articles and run softwares and getting results ....
Hoping some genius persons will change this way...
