Three-Dimensional Responses of a Tied-Back Excavation through Clay
Author: Richard J. Finno and Jill F. Roboski | Size: 755 KB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2005 | pages: 10
The three-dimensional ground deformations measured during construction of a 12.8 m deep tiedback excavation in Chicago are presented. The excavation was supported by a PZ-27 sheet pile wall and three levels of regroutable ground anchors. The excavation was made through granular soils into soft to medium stiff clays. Extensive field performance data were collected including lateral and vertical optical survey data and lateral inclinometer data. Construction procedures are summarized and correlated with monitoring data. The three dimensional pattern of ground surface deformations around the excavation is summarized. A performance-based relation to estimate the maximum horizontal ground movements for flexible wall systems as a function of factor of safety against basal heave and excavation depth is proposed. An empirical approach to estimate the distribution of ground movements parallel to a supported wall is presented.

Contributions to static and seismic analysis of piles and pile-supported bridge piers
Author: George Mylonakis | Size: 7.7 MB | Format:PDF | Quality:Unspecified | Publisher: State University of New York at Buffalo | Year: 1995 | pages: 312
A number of solutions are presented for the static, dynamic, and seismic response
of single piles, pile groups, and pilewgroup-supported bridge piers, on homogeneous and
layered soil deposits. Vertical, horizonta~ and moment loading are considered, and results
are presented in terms of both analytical closed-form expressions and
numerically-evaluated graphs. The seismic analysis considers both the kinematic and
inertial interaction, in the frequency as well as the time domains, with the excitation
properly specified through the acceleration at the surface ofthe "rock" outcrop.
The developed methods make use of certain physically-motivated simplifications
regarding the wave fields around an oscillating pile and the interplay of such fields with
other piles. Thus diffraction of the incident seismic waves by a pile and of the
pile--generated waves by other piles is represented in a realistic, although simplified, way.
The accuracy of the developed methods is systematically checked against available
solutions from the literature, as well as against a few field measurements.
The new developments in this dissertation include : (i) the presentation of solutions
for pile-to-pile interaction in multi-layered soil, and the demonstration of the profound
effect of soil layering on this interaction; (ii) the recognition and presentation of numerical
and analytical results for the "additional distress" on a pile from the waves emanating
from the neighboring piles; and (iii) the evaluation of certain popular approximations in
soil-structure-interaction analyses as performed in practice, such as ignoring the kinematic
response, ignoring the various types of radiation damping, assuming frequency-
independent stiffuesses, and artificially restricting pile--cap rotation.

- Provides the necessary functional knowledge of the track behaviour, covering the function of the various track components, their interaction as elements of the track system, and the interaction of the systems track and railway vehicles;
- Presents important tools and future challenges for infrastructure managers;
- Supplemented with an historical analysis of railway;
A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality. Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. Albert Einstein said, “You have to learn the rules of the game. And then you have to play better than anyone else.” Only if we understand how the whole system works, taking into account its imperfections and how they influence its quality and performance will we be able to learn the rules of the game and “play better.” The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.

EUROSTEEL 2011, 6th European Conference on Steel and Composite Structures.
According to the traditions, the Conference offers a platform to discuss a wide range of problems related to great variety of research, design and construction activities. We can confidently say that the Eurosteel conferences have developed into one of the most important events for European steel researchers and designers: the Conference in Budapest attracts more than 500 international delegates of structural engineers and research institutes; more than 400 papers from 50 countries around the world are presented. Needless to say, today’s success would have not been achieved without the extensive efforts, contribution and the continuous expansion of the Conferences held earlier in Athens (1995), Prague (1999), Coimbra (2002), Maastricht (2005) and Graz (2008). The proceedings of the Conference include 424 papers in 3 volumes on more than 2500 pages. The contributions cover state-of-the-art of the current activities on steel and composite structures. All papers were reviewed by the Scientific Committee; their voluntary work is gratefully acknowledged.
The Editors wish to express their gratitude to the ECCS, the publisher of the proceedings for the significant financial and technical help for the organizers. The members of the Organizing Committee, an enthusiastic team at the Department of Structural Engineering of BME and a large number of sponsors supported the organization of the Conference what is highly appreciated.

Nanotechnology in eco-efficient construction
Author: Fernando Pacheco-Torgal, Maria Vittoria Diamanti, Ali Nazari and Claes-Goran Granqvist | Size: 12.8 MB | Format:PDF | Quality:Original preprint | Publisher: Woodhead publishing | Year: 2013 | pages: 453 | ISBN: 0857095447
As the environmental impact of existing construction and building materials comes under increasing scrutiny, the search for more eco-efficient solutions has intensified. Nanotechnology offers great potential in this area and is already being widely used to great success. This book is an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction.
Following an introduction to the use of nanotechnology in eco-efficient construction materials, part one considers such infrastructural applications as nanoengineered cement-based materials, nanoparticles for high-performance and self-sensing concrete, the use of nanotechnology to improve the bulk and surface properties of steel for structural applications and nanoclay-modified asphalt mixtures and safety issues relating to nanomaterials for construction applications. Part two discusses applications for building energy efficiency, including thin films and nanostructured coatings, switchable glazing technology and third generation photovoltaic (PV) cells, high-performance thermal insulation materials, and silica nanogel for energy-efficient windows. The focus of part is photocatalytic applications; chapters investigate nanoparticles for pollution control, self-cleaning and photosterilization and the role of nanotechnology in manufacturing paints and purifying water for eco-efficient buildings.

Eco-efficient concrete
Author: Joao Labrincha, Fernando Pacheco-Torgal and Said Jalali | Size: 37 MB | Format:PDF | Quality:Unspecified | Publisher: Woodhead Publishing | Year: 2013 | pages: 624 | ISBN: 9780857094247
Concrete is one of the most widely-used of all materials with a significant environmental impact. This important book reviews the wealth of recent research on developing more eco-efficient concrete. The editors have compiled contributions from an international group of authors which review a wide range of technologies and strategies. The book presents a very useful input for producing more ecologically friendly concrete. It achieves this goal by dealing with the impact of the concrete from a variety of viewpoints: the concrete constituents themselves, cement and concrete, the concrete as a whole, the application of wastes and by-products, the use of natural materials of low environmental impact, as well as exploring new types of binders.
The opening sections discuss the eco-efficiency and life cycle assessment of Portland cement concrete and consider concrete with supplementary cementitious materials (SCMs). Part three focuses on concrete with non-reactive wastes, including municipal solid waste incinerator (MSWI) concrete, concrete with polymeric, construction and demolition wastes (CDW) and offers an eco-efficient approach to concrete carbonation. The conclusion investigates future alternative binders and the use of nano and biotech in concrete production.
