[Thesis] Performance-Based Earthquake Engineering With The First-Order Reliability
Author: SMITHA DEVI KODURU | Size: 1.36 MB | Format:PDF | Publisher: The University of British Columbia | Year: 2008
Performance-based earthquake engineering is an emerging field of study which complements the
prescriptive methods that the design codes provide to ensure adequate seismic performance of structures.
Accounting for uncertainties in the performance assessments forms an important component in this area.
In this context, the present study focuses on two broad themes; first, treatment of uncertainties and the
application of the first-order reliability method (FORM) in the finite-element reliability analysis, and
second, the seismic risk assessment of reinforced concrete structures for performance states such as,
collapse, and monetary loss. In the first area, the uncertainties arising from the inherent randomness in
nature (aleatory) and due to the lack of knowledge (epistemic) are identified. A framework for the
separation of these uncertainties is proposed. Following this, the applicability of FORM to the linear and
nonlinear finite-element structural models under static and dynamic loading is investigated. The case
studies indicate that FORM is applicable for linear and nonlinear static problems. Strategies are proposed
to circumvent and remedy potential challenges to FORM. In the case of dynamic problems, the
application of FORM is studied with an emphasis on cumulative response measures. The limit-state
surface is shown to have a closed and nonlinear geometric shape. Solution methods are proposed to obtain
probability bounds based on the FORM results. In the application-oriented second area of research, at
first, the probability of collapse of a reinforced concrete frame is assessed with nonlinear static analysis.
By modelling the post-failure behaviour of individual structural members, the global response of the
structure is estimated beyond the component failures. The final application is the probabilistic assessment
of monetary loss for a high-rise shear wall building due to the seismic hazard in the Cascadia Subduction
zone. A 3-dimensional finite-element model of the structure with nonlinear material models is subjected
to stochastic ground motions in the reliability analysis. The parameters for stochastic ground motion
model are developed for Vancouver, Canada. Monetary losses due to the damage of structural and nonstructural
components are included.

This book is a comprehensive guide to the techniques and materials for accurate small-scale modelling with chapters by leading international researchers and engineers. In particular, impact, earthquake and dynamic problems are presented for the first time covering reinforced and pre-stressed concrete.
In order to determine the behaviour of engineering processes, components or structures, numerical or physical modelling is usually undertaken. The physical modelling of a reinforced concrete structure is a typical example in which the model represents a complete structure or part of a structure. The scale of a model should be as large as possible but practical laboratory constraints will dictate the model size.

Product Description:
Stressing basic engineering concepts and methods of analysis used in the design of structures subject to dynamic environmental loads, such as earthquake ground motions, ocean surface wave forces and severe storm wind pressures, this book approaches randomness or uncertainty in loads through probabilistic and statistical methods using simple engineering terms with a minimum amount of advanced mathematics. Among the topics discussed are several new areas of interest to engineers: random load modelling, time dependent random loads, continuous structural systems and nonlinear structures. Included are numerous useful engineering examples and exercises.

Would you please provide me with a link for the following book by Smith and Griffiths:
"Numerical Methods for Engineers", D.V. Griffiths and I.M. Smith, 2nd ed., Chapman & Hall/CRC Press, 2006.
Please note that it is different from the one by "Steven C Chapra" as listed in CIVILEA somewhere else!

Developments in Earthquake Engineering have focussed on the capacity and response of structures. They often overlook the importance of seismological knowledge to earthquake-proofing of design. It is not enough only to understand the anatomy of the structure, you must also appreciate the nature of the likely earthquake.
Seismic design, as detailed in this book, is the bringing together of Earthquake Engineering and Engineering Seismology. It focuses on the seismological aspects of design – analyzing various types of earthquake and how they affect structures differently. Understanding the distinction between these earthquake types and their different impacts on buildings can make the difference between whether a building stands or falls, or at least to how much it costs to repair.
Covering the basis and basics of the major international codes, this is the essential guide for professionals working on structures in earthquake zones around the world.

As a suggestion, I humbly request that you choose font colours, while posting material on the forum, that will not strain our eyes while perusing thru your postings especially as regards the main body of the text. If you can read it clearly, then we may be able to read it too. Check this before posting and dont mind the fancy nature of your post.
I would say the default font colour works just fine.

Guidelines for the Design and Construction of Externally Bonded FRP Systems for Strengthening Existing Structures
Author: Task Group | Size: 0.95 MB | Format:PDF | Publisher: NATIONAL RESEARCH COUNCIL | Year: 2005 | pages: 58
The present document adds to the series of documents recently issued by the CNR on the structural
use of fibre-reinforced polymer (FRP) composites, started with the publication of CNR-DT
200/2004. The topic of the present document is the use of externally bonded systems for
strengthening timber structures.
This is an informative document. The intended objectives of this document are to disseminate,
within the professional community, the current knowledge on the use of FRPs for strengthening of
timber structures, and to provide the necessary information to identify cases where the use of FRPs
for strengthening applications is appropriate and safe.
It is well-known that the current state of the art on this topic is not as advanced as that on concrete
and masonry structures. Accordingly, no international guidelines on the use of FRPs for
strengthening of timber structures are available at present. In this context, the present document
represents the first step towards the development of specific design guidelines. These guidelines
will be issued in the near future, once the theoretical and experimental studies currently underway
internationally, will produce a more complete and consolidated understanding of the subject.
This document will then be useful to identify any still unsolved problems , therefore allowing the
scientific community to focus on them over the next years, and will become a reference document
on this topic.
The current version of this document contains some basic concepts on FRP strengthening and on
related specific problems, on strengthening of structural members under combined bending and
axial force, with particular reference to strengthening of wooden floors and their stiffening under inplane
loads. Some qualitative aspects of debonding issues and of strengthening of joints are also
addressed.
Finally, three Appendices are included, which present several examples of FRP strengthening
interventions on structures (Appendix A), the main technical references (Appendix B) and the
design code references on the subject (Appendix C).
