Polymeric materials are being used in earthworks construction with ever increasing frequency. The term "Geosynthetics" was recently coined to encompass a diverse range of polymeric products designed for geotechnical purposes. One such purpose is the tensile reinforcement of soil~. As ten­ sile reinforcement, polymers have been used in the form of textiles, grids, linear strips and single filaments to reinforce earth structures such as road embankments, steep slopes and vertically faced soil retaining walls. A considerable number of retaining structures have been successfully con­ structed using the tensile reinforcing properties of "geosynthetics" as their primary means of stabilization. Despite such successes sufficient uncertainty exists concerning the performance of these new materials, their manner of interaction with the soil and the new design methods needed, that many authorities are still reticent concerning their use in permanent works. This book represents the proceedings of a NATO Advanced Research Workshop on the "Application of Polymeric Reinforcement in Soil Retaining Struc­ tures" held at the Royal Military College of Canada in Kingston, Ontario from June 8 to June 12, 1987. The initial concept for the workshop occur­ red during the ISSMFE Conference in San Francisco in 1985 when a group of geotextile researchers mooted the idea of hoiding a "prediction exercise" to test analytical and design methods for such structures.

Hybrid Coupled Wall (HCW) systems are lateral-force-resisting systems composed of reinforced concrete walls coupled by steel beams. Extensive research has shown that HCW systems possess the necessary combination of stiffness, strength, and toughness for application in regions of moderate to high seismicity. "Recommendations for Seismic Design of Hybrid Coupled Wall Systems" synthesizes the existing information into helpful recommendations for engineers and practitioners involved with seismic analysis and design of HCW systems. This book offers two methods for system design - a prescriptive design method based on linear elastic analysis and an all-purpose performance-based design method that can be used in conjunction with linear or nonlinear analysis techniques. Guidelines for preliminary system proportioning are also provided along with recommendations for component design. This book will be valuable to engineers and professionals involved in seismic analysis.

The Second Edition of Earth Structure: An Introduction to Structural Geology and Tectonics takes a balanced approach to the subject―emphasizing links between structural features at all scales (microscopic, hand-specimen, outcrop, mountain-range) and deformation processes. Earth Structure shows how assemblages of structures relate to different geological settings in the context of plate tectonics. Chapters are self-contained modules that can be arranged in various sequences depending on instructor preference, and the book uses a conversational writing style, employing familiar analogies and field examples. Mathematical analysis, where used in the book, is kept at a basic level.

Popular features include: • Self-contained chapters on deformation mechanisms (both brittle and plastic) and deformation products (fractures, faults, folds, and fabrics) that allow instructors to provide a foundation of understanding on "how" deformation takes place, as well as a thorough description of what deformation causes. • Whole chapters on tectonic settings. These chapters allow the book to be used either for a one-semester course that relates deformation to tectonic settings or for a succession of two courses (one on structure and one on tectonics), thus enabling students to buy just one book. • Essays on Regional Perspectives that provide information on tectonic analysis for eleven regions around the globe written by specialists in the area―discussions include the European Alps, the Altaids, the Appalachians, and the Cascadia Wedge. • Over 570 detailed figures providing informative illustration of concepts.

Earth structures engineering involves the analysis, design and construction of structures, such as slopes and dams, that are composed mainly of earth materials, and this is a growth area in geotechnical engineering practice. This growth is due largely to increased involvement in designing various types of earth structures for the resources industries (slopes, impoundment structures, offshore islands, mine backfills), to the development of increas­ ingly large hydroelectric projects, to the need for more freshwater storage and diversion schemes, and to the need for transportation, communications and other facilities in areas where the natural earth materials are occasionally subject to mass instabilities. Although geotechnical engineering transects traditional disciplinary boundaries of civil, geological and mining engineering, the majority of geotechnical engineers are graduates from civil engineering schools. Here the geotechnical instruction has been concentrated on soil mechanics and foundation engineering because foundation engineering has traditionally been the major component of geotechnical practice. Geotechnical special­ ists, however, generally have acquired considerable formal or informal training beyond their first engineering degree, and an advanced degree with considerable cross-discipline course content is still considered an advantage for a young engineer entering a career in geotechnical engineering. Practical job experience is, of course, a necessary part of professional development but is readily interpreted and assimilated only if the required background training has been obtained.

ENERCALC Structural Engineering Library v6.16.8.31 [Size: 233.4 MB] ... The core of ENERCALC are calculation modules. Dating back to 1983 when the Structural Engineering Library was released as a set of spreadsheet templates, our modules are designed as “fill-in-the-blanks” style of interactive programs. Simply type in a value and the resulting analysis or design is instantly there for your review.

All modules in Version 6 conform to IBC 2006/2009/2012/2015, CBC 2007/2010/2013, ASCE 7-05/7-10, ACI 318-05/08/11/14, ACI 530-05/08/11/12, AISC 360-10, NDS 2015, 2012 & 2005.
The calculation module list is an ever-expanding set of structural calculations that provide analysis and design for the elements of a building. As requests are received from our users we develop additional modules ... and make use of the proven steel, concrete, timber, finite element analysis, and other engineering “solvers” we have developed.

Essential to any project are the standard construction products that the engineer will employ to develop the final structure. ENERCALC provides databases of all typical rolled steel sections, sawn wood and engineered lumber sections, material grades for steel and wood and small databases for concrete block and rebar. In addition the user can create their own steel section databases and also mark “favorite” items in all databases to simplify the work according to their most frequent needs.

ENERCALC software provides well designed calculation reports for all of its modules. Using the full capabilities of modern printers we combine highly readable font styles with well laid out calculation reports and integrated graphics.

The goal of our reports is to provide clarity and efficiency. This benefits the reviewing engineer and governmental plan check reviewer by providing well laid out, concise and thorough report that details the structural design. New technology has given us the gift of low cost color on printouts, and this benefits us all by allowing us to incorporate contrasting colors to call attention to warnings or overstress conditions.
All printouts conform to 8.5” x 11” typical United States paper sizes, and the user is also free to customize title block layouts and add company logos and a P.E. seal.

Dry stone retaining structures are structures made of individual decimeter stone blocks in contact. One advantage of this construction technology lies in the weak amount of embodied energy required for their construction, and uses only local materials. This technology may be a positive answer to the challenges brought by sustainable policies in civil engineering.

Many of these structures are older than one hundred years and sustain damage due to ageing; this places the owners in front of a challenging issue. Usual scientific tools cannot address the specific behavior of such structures. Due to the discrete nature of the system, a large amount of energy can be dissipated at contact level before failure of the structure. The shape, arrangement and possible breakage of blocks may play a major role in their overall behavior, specific to these structures. This book brings an overview of the DEM technique to model the behavior of discrete civil engineering structures. Physical models, modeling and site measurements are all explored, helping the civil engineer evaluate the behavior of unique structures.

The only DEM technique to model the behavior of discrete civil engineering structures + A specific and sophisticated tool to address the general features observed on site + Details physical models, modeling and site measurements.

The third edition of a successful engineering text, Design of Liquid Retaining Concrete Structures clarifies the theoretical guidance given in the new suite of Eurocodes for the subject of retaining structures. The book qualifies the extensive set of guides in terms of the design of these structures and provides a clear path through the process. It still discusses structural elements individually so that expertise can be applied to any situation likely to be encountered. The modifications, such as changes to surface zones, the critical steel ratio, the maximum crack spacing (flexural and imposed strain) and edge restraint, that have been introduced into the Eurocodes are highlighted and discussed in detail.

The new suite of Eurocodes is claimed to be the most technically advanced codes in the world; the codes were developed with the intention of making them less restrictive than existing codes. The third edition reflects this philosophy by providing more theoretical background information and discussion, with specific reference to current and previous research, helping the reader to achieve a greater understanding and a wider application of the basic design guidance as the codes intended. As such the book remains a vital tool for practicing civil and structural engineers.

The foundation of structures and the construction of underground railways in urban areas would be impossible without the use of diaphragm walls, grouting, anchors, micropiles, slender retaining walls, etc. Based on the author's own experience and taking into account the findings of various other authors, this book explains these methods in an intelligible manner, enabling the reader to judge for himself their suitability in construction practice. The aim of the book is to instruct experts in the correct application of grouting methods, and the correct choice of drilling systems and tools. It provides mainly practical information, and describes the most suitable, up-to-date technology available. Grouting applications in Czechoslovakia and abroad are illustrated by a series of practical examples. The book is designed for students of civil engineering faculties specializing in structural foundation, specialists of building companies, and experts in structural foundation. It will also be appreciated by experts in underground railway and tunnel construction, in structural engineering and urban development (landslides), as well as by manufacturers of the respective technology.
