  COLLAPSE ASSESSMENT OF CONCRETE BUILDINGS: AN APPLICATION TO NON-DUCTILE REINFORCED C

COLLAPSE ASSESSMENT OF CONCRETE BUILDINGS: AN APPLICATION TO NON-DUCTILE REINFORCED CONCRETE MOMENT FRAMES

Author: Majid Baradaran Shoraka | Size: 9.3 MB | Format: PDF | Quality: Unspecified | Publisher: THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Civil Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) | Year: august 2013 | pages: 251

Existing reinforced concrete buildings lacking details for ductile response during earthquake shaking represent prevalent construction type in high seismic zones around the world. Seismic rehabilitation of these existing buildings plays an important role in reducing urban seismic risk; however, with the massive inventory of existing concrete buildings and high costs of seismic rehabilitation, it is necessary to start by identifying and retrofitting those buildings which are most vulnerable to collapse. The collapse of most non-ductile concrete buildings will be controlled by the loss of support for gravity loads prior to the development of a side-sway collapse mechanism. “Gravity load collapse” may be precipitated by axial-load failure of columns, punching-shear failure of
slab-column connections, or axial-load failure beam-column joints. In this dissertation, systemlevel collapse criteria are developed and implemented in a structural analysis platform to allow for a more accurate detection of collapse in these existing moment frames. Detailed models for primary components, which may precipitate gravity-load collapse of the concrete moment frame, are first required to achieve this objective and develop the collapse
assessment framework. An analytical model based on mechanics is developed to reliably capture the lateral load–deformation response of a broad range of reinforced concrete columns with
limited ductility due to degradation of shear resistance, either before or after flexural yielding.
The robust collapse performance assessment could be used for many structural applications. In this dissertation, it is used to identify collapse indicators, design and response
parameters that are correlated with “elevated” collapse probability. The collapse assessment framework is also used to identify the relative collapse risk of different rehabilitation techniques.vFinally, the framework is used to estimate the impact of collapse criteria on the expected financial losses for existing concrete frame buildings in high seismic zones.

  FIB 48: Formwork and falsework for heavy construction
Posted by: oscargon - 12-28-2013, 07:30 AM - Forum: Concrete - Replies (2)

FIB 48: Formwork and falsework for heavy construction

Author: fib Task Group 10.2 | Size: 8.59 MB | Format: PDF | Quality: Original preprint | Publisher: International Federation for Structural Concrete (fib) | Year: 2009 | pages: 96 | ISBN: 978-2-88394-088-8

Abstract:

The realization process of civil engineering structures is complicated, involving a wide variety of disciplines, each of which brings a specific contribution. It is a challenge to structure the process so that a balanced, optimized participation of the many disciplines involved is achieved. One of the critical success factors is knowledge management: each discipline should bring professional knowledge, but they should interact at interfaces as well.

Temporary structures are an example of this phenomenon: they are right in the middle of a complex system of interactions between structural engineering, site engineering, work preparation, procurement, and execution. They have a significant impact on cost, construction time, construction methodology and the through-life performance of the actual structure.

Formwork and falsework are among the most important elements of temporary structures for civil engineering projects. Knowledge management with respect to formwork and falsework requires engineers to share knowledge and experience in the broadest sense, as the actual performance of formwork and falsework can only be evaluated at a late stage in the realization process, when some disciplines are no longer present. The learning circle can therefore only be closed through feedback.

fib Bulletin 48 presents an overview of formwork and falsework techniques and addresses issues related to the design and application thereof. Its objective is to bridge the gap often experienced in practice by effectively feeding back state of the art knowledge and experience with regard to formwork and falsework, thus making a larger group of engineers familiar with the important issues related to the design and application of formwork and falsework. It aims to provide both structural and site engineers with information to design and use formwork and falsework in a safe, reliable, and economic way, thus achieving better interaction between the engineering disciplines involved.

Bulletin 48 addresses some fundamental issues related to formwork and falsework:

- The appearance of the finished concrete, which is closely related to the quality of the formwork.
- The performance of the finished concrete in relation to durability and as part of Life Cycle Management.
- The need to support the concrete while it acquires enough strength and stiffness to support itself. In this context the most important issue is structural safety.

The guidelines given in this document are based on the experience of site and design engineers; and most of the advice is a consequence of real problems experienced in the past. Any warnings based solely on theoretical judgment have been avoided; only recommendations based on experience have been included.

fib Bulletin 48 focuses on principles only, and therefore does not address detailed design issues, for which local design codes should be applied.

  Reliability of Structures, Second Edition
Posted by: fred2010 - 12-28-2013, 07:24 AM - Forum: Archive - No Replies

Reliability of Structures, Second Edition

Author: Andrzej S. Nowak, Kevin R. Collins | Size: ? MB | Format: PDF | Quality: Unspecified | Publisher: CRC | Year: 2013 | pages: 407 | ISBN: 0415675758 - 978-0415675758

[Image: 12626949347272577143.png]


[Image: info.png]

Features
Suitable for both students and professionals
Assumes little mathematical background
Written with an applied focus, with only enough mathematics and engineering theory to empower the reader
Rich in useful worked examples
A solutions manual is available upon qualifying course adoption
Summary
Reliability of Structures enables both students and practising engineers to appreciate how to value and handle reliability as an important dimension of structural design. It discusses the concepts of limit states and limit state functions, and presents methodologies for calculating reliability indices and calibrating partial safety factors. It also supplies information on the probability distributions and parameters used to characterize both applied loads and member resistances.
This revised and extended second edition contains more discussions of US and international codes and the issues underlying their development. There is significant revision and expansion of the discussion on Monte Carlo simulation, along with more examples.
The book serves as a textbook for a one-semester course for advanced undergraduates or graduate students, or as a reference and guide to consulting structural engineers. Its emphasis is on the practical applications of structural reliability theory rather than the theory itself. Consequently, probability theory is treated as a tool, and enough is given to show the novice reader how to calculate reliability. Some background in structural engineering and structural mechanics is assumed.
A solutions manual is available upon qualifying course adoption.

  HAPPY 5 TH. BIRTHDAY CivilEA
Posted by: ykhackhack - 12-25-2013, 09:12 AM - Forum: Free Discussion - No Replies

I would like to take this opportunity to thank everybody in this forum who are trying to help others.

Especially Dear Admin and All of the Moderators, who use their own resources to help people.

I admire people who give to others, and don't ask anything back, like CivilEA community.

Unfortunately and undeniably there are some people who only take, we can not do anything about that, that is the way it is.
May be someday they wake up, hopefully.

If you are fortunate enough to become part of this forum, please consider helping.
And please be aware of the others' time and effort who try to help.

And if you can spare an even small donation, don't wait, do it.

Thank you
Best to ALL CivilEAns

Dear All;

Five years ago on "24-Dec-2008" forum.civilea.com was born. Before this date, originally we start our works from "4downloader.blogspot.com" weblog on "12-April-2007" then we immigrate to "4Downloader.veb.ir" then "4Downloader.ir" domain, Finally, during a poll of members, we sellect "CivilEA.com" as our main domain and it was our brand.

At now, we are the best and well organized Civil Engineering Community in the world, this is the result of all users of CivilEA.
we are a large community with more than 87000 registered users. now every civil engineers in the world know CivilEA.

I want to say my special thanks to all moderators that spend their valuable time here to organize forum, without them CivilEA could not reached here.

Our forum have about 24000+ thread, 81000+ posts. I note that we do not permit useless posts.

I want to say my another special thanks to all active and also VIP users that help me and all CivilEA users to have more and more.

[Image: 15275939935676058888.jpg]

me as administrator of CivilEA spend my main time for improving server and security of them, loading and maintenance of large website like CivilEA is not easy.

We have special and fantastic plan for next year, we try to bring you new feature.
