Report of a Working Party of The Concrete Society in collaboration with the Concrete Bridge Development Group. This fully revised and updated edition provides bridge engineers with authoritative, practical guidance on designing, specifying and constructing durable post-tensioned concrete bridges. A multi-layer protection approach to durability of post-tensioned construction is presented. The standards and practices outlined in the core of the Report are a package of design, materials and construction measures. For prestressing, quality forms the basis of the recommendations. It links recommended design details, specifications for duct and grouting systems, and a quality assurance scheme for supply and installation of post-tensioning systems. The scope of this second edition has been extended to include; external unbonded prestressing remedial (void) grouting of existing bridges updated information on new test methods. 70pages.

  Durability of Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC)
Posted by: ir_71 - 12-13-2010, 05:25 AM - Forum: Concrete - Replies (2)

Durability of Strain-Hardening Fibre-Reinforced Cement-Based Composites

Author: Van Zijl, G.P.A.G.; Wittmann, F.H. (Eds.) | Size: 3.8 MB | Format: PDF | Publisher: Springer | Year: 2010 |
pages: 978-94-007-0337-7 | ISBN: 978-94-007-0337-7

Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC) were named after their ability to resist increased tensile force after crack formation, over a significant tensile deformation range. The increased resistance is achieved through effective crack bridging by fibres, across multiple cracks of widths in the micro-range. Whether these small crack widths are maintained under sustained, cyclic or other load paths, and whether the crack width limitation translates into durability through retardation of ingress of moisture, gas and other deleterious matter, are scrutinized in this book by evaluation of test results from several laboratories internationally. The durability of SHCC under mechanical, chemical, thermal and combined actions is considered, both for the composite and the fibre types typically used in SHCC. The compilation of this state-of-the-art report has been an activity of the RILEM TC 208-HFC, Subcommittee 2: Durability, during the committee life 2005-2009.

  Rank of users and options enabled
Posted by: datagap - 12-12-2010, 11:36 PM - Forum: Suggestion & Complains - Replies (5)

Dear moderators and Admin,

I think, there is  a necessity to be posted a list of options that are enabled only for registered users/vips/moderators when they post, use their CP, ect.

For example, I've found that I can't send private messages (probably, because of my rank?). I read that someone, also inactive, had tried to attach a file but he/she couldn't (because of the rank). Another one had inserted a hyperlink (such option exists) and received warning.

That's why, please, provide us with some more clearness about the dependence of the options enabled  on the rank of the user. I suppose, it will not cost you so much effort, but will be very useful to all - both inactive users and moderators. Knowing what we are allowed to do and what - not, we will not spend time in trying disabled options,  and reporting non-existing bugs. This will save your time too.

Excuse me, in the case that all this is somewhere explained. I read the rules, I searched by key words, but I could't find.

Thank you in advance,
Regards

Curtain Walls - Recent Developments by Cesar Pelli & Associates

Author: Michael J. Crosbie | Size: ZIP 32.6 MB | Format: PDF | Publisher: Birkhäuser Basel Architecture; | Year: 2005-12-01 | pages: 177 | ISBN: ISBN-10 / ASIN: 3764370831; ISBN-13 / EAN: 9783764370831

Book Description:

The curtain wall—a non-bearing wall attached to a building's structural frame like a curtain made of metal or, more likely
glass—is an omnipresent feature of contemporary architecture. Variations of pattern and color, transparency and opacity offer
the architect almost limitless design possibilities, a tremendous palette for "skinning" the structural frame of buildings from museums to skyscrapers.There are few practitioners of curtain wall design as accomplished as Cesar Pelli & Associates, and this book presents twenty of their most exemplary projects. Arranged by material—glass, metal, stone—the conception and development of each individual facade is revealed and construction details comprehensively documented through numerous drawings. Any practicing architect interested in state-of-the-art curtain wall design will need to own this indispensable and inspiring book.

Aeroelastic and structural dynamic phenomena play an important role in many facets of engineering. In particular, an understanding of these disciplines is essential to the design of aircraft and space vehicles and longest suspension bridge. This text provides an introduction to structural dynamics and aeroelasticity, with an emphasis on conventional aircraft. The primary areas considered are structural dynamics, static aeroelasticity, and dynamic aeroelasticity. The structural dynamics material emphasizes vibration, the modal representation, and dynamic response. Aeroelastic

This is a well-known classic thesis from Caltech entitled: the response of nonlinear multi-story structures subjected to earthquake excitation. The thesis has proposed the One-Component and Two-Component Beams model, a model to represent a nonlinear beam which has used the combination of spring - linear element - spring. This model was then enhanced and hence known as lumped plasticity model which is currently available in SAP2000/ETABS/Ruaumoko/OpenSees. In Ruaumoko, the author name is used as the name of a nonlinear elements in FRAME element (so-called Giberson beam).

The thesis is very useful in understanding the nonlinear model of beam especially for those who are interesting in analytical modelling.
