EUROROCK 2013











Rock Mechanics for Resources, Energy and Environment
 Autor: Kwasniewski,Marek, Lydzba,Dariusz


This book contains the Proceedings of EUROCK 2013 – The 2013 ISRM International Symposium, which was held on 23-26 September 2013 in Wroclaw, Poland. The Symposium was organized by the ISRM National Group POLAND and the Institute of Geotechnics and Hydrotechnics of the Wroclaw Institute of Technology. The focus of the Symposium was on recent developments in the field of rock mechanics with an emphasis on the application of rock mechanics to the extraction of natural resources, securing energy supplies and protecting of the environment surrounding rock that is subjected to engineering activities.
The main topics, which were covered in the 150 papers (including six keynote papers) that make up this book are: rock mass characterization, laboratory and in-situ testing, constitutive models and numerical modeling, mathematical modeling of THM processes in rocks, mine design and ground control, underground storage and waste disposal, slope and open pit stability, dynamic phenomena in rock masses, design methodology in rock engineering, mechanical breakage of rocks, rock tunnel excavation and support, petroleum rock mechanics and geological CO2 sequestration. The book also includes the 2013 ISRM Franklin Lecture by A. Goricki on the engineering aspects of geotechnical tunnel design.
The book will be of interest and value to rock mechanics researchers as well as to professionals who are involved in the various branches of rock engineering.

Combining a theoretical background with engineering practice, Design of Steel-Concrete Composite Bridges to Eurocodes covers the conceptual and detailed design of composite bridges in accordance with the Eurocodes. Bridge design is strongly based on prescriptive normative rules regarding loads and their combinations, safety factors, material properties, analysis methods, required verifications, and other issues that are included in the codes. Composite bridges may be designed in accordance with the Eurocodes, which have recently been adopted across the European Union. This book centers on the new design rules incorporated in the EN-versions of the Eurocodes.
The book addresses the design for a majority of composite bridge superstructures and guides readers through the selection of appropriate structural bridge systems. It introduces the loads on bridges and their combinations, proposes software supported analysis models, and outlines the required verifications for sections and members at ultimate and serviceability limit states, including fatigue and plate buckling, as well as seismic design of the deck and the bearings. It presents the main types of common composite bridges, discusses structural forms and systems, and describes preliminary design aids and erection methods. It provides information on railway bridges, but through the design examples makes road bridges the focal point.
This text includes several design examples within the chapters, explores the structural details, summarizes the relevant design codes, discusses durability issues, presents the properties for structural materials, concentrates on modeling for global analysis, and lays down the rules for the shear connection. It presents fatigue analysis and design, fatigue load models, detail categories, and fatigue verifications for structural steel, reinforcement, concrete, and shear connectors. It also covers structural bearings and dampers, with an emphasis on reinforced elastomeric bearings. The book is appropriate for structural engineering students, bridge designers or practicing engineers converting from other codes to Eurocodes.

CURING CONCRETE



 

 CURING CONCRETE
 Taylor,Peter C.

Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it.
The book covers:
  • The fundamentals behind hydration
  • How curing affects the properties of concrete, improving its long-term performance
  • What curing technologies and techniques you can use for different applications
  • How to effectively specify, provide, and measure curing in a project
The author also gives numerous examples of how curing—or a lack of it—has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.

DESIGN AND PERFORMANCE OF EMBANKMENT ON VERY SOFT SOILS














 

DESIGN AND PERFORMANCE OF EMBANKMENT ON VERY SOFT SOILS
Marcio de Souza S. Almeida, Maria Esther Soares Marques

Embankment construction projects on very soft soil often give rise to serious problems. This volume on geotechnics and soft soil engineering therefore treats all phases of the design and construction process exhaustively, from the first investigation step to the monitoring of constructed work. The book presents the development concepts necessary for the project stages and discusses in great detail construction methods, displacement estimations, stability analyses, monitoring, and various other aspects involved. Extensive attention is furthermore paid to the application of geosynthetics as a tool to improve the stability of soft soils and embankments. Including various tables and practical data for many geographical areas in the world, this reference volume is essential reading for engineers and researchers in geotechnical engineering, construction, and related disciplines.

GEOTECHNICS AND HERITAGE.CASE HISTORIES
Emilio Bilotta,Alessandro Flora
Conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical, economical and administrative factors, intertwining in inextricable patterns. The complexity of the topic is such that guidelines or recommendations for intervention techniques and design approaches are difficult to set.
The Technical Committee on the Preservation of Monuments and Historic Sites (named TC19) was established by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 1981, is supported by the Italian Geotechnical Society (AGI), and renamed TC301 in 2010. Geotechnics and Heritage, collects relevant case histories on the role of geotechnical engineering in the preservation of monuments and historic sites, and is an addition to the Proceedings of the two International Symposia organized by the Committee in Napoli in 1994 and 2013. The contributions in the book proof the significant role geotechnical engineering plays in conservation of historic building and monuments
