Author: Norbert J. Delatte, Jr. | Size: 7 MB | Format:PDF | Quality:Original preprint | Publisher: American Society of Civil Engineers | Year: 2009 | pages: 401 | ISBN: 9780784409732
Engineering failures get a lot of attention—inciting morbid curiosity and fueling concern over the condition of our infrastructure. But every engineering loss is the start of a forensic investigation into how, why, and what can be done to prevent future failures. As with scientific failures, engineering failures can be very instructive in teaching us what does not work.
Beyond Failure presents the circumstances of important failures that have had far-reaching impacts on civil engineering practice. Each case study narrates the known facts: design and construction, the failure, subsequent investigation or analysis, and, where appropriate, additional issues such as technical concerns, ethical considerations, professional practice issues, and long-term effects. The case studies are organized around eight common topics of undergraduate engineering courses and include teaching points and a reading list, so this book is useful to engineering faculty and students. With more than 40 full cases, including the Silver Bridge collapse in Point Pleasant, WV; the levee breaches in New Orleans, LA; and the Challenger space shuttle explosion, this book will also appeal to practicing engineers with an interest in forensic investigations or the analysis of historic failures.

Preparing for Design-Build Projects: A Primer for Owners, Engineers, and Contractors
Author: Douglas D. Gransberg, James E. Koch and Keith R. Molenaar | Size: 7 MB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2006 | pages: 290 | ISBN: 9780784408285
For nearly two decades, design-build (DB) contracting has become increasingly the method of choice in public and private construction projects. Many designers and builders are now drawn to design-build projects and must alter their business practices to accommodate the changed relationships within DB contracts.
Preparing for Design-Build Projects: A Primer for Owners, Engineers, and Contractors is a professional reference that covers the basics of developing a design-build project. The authors focus on learning modules that break down the decision-making process and reassemble it as a straightforward method for DB projects from the owner's standpoint. This book acts as a timely guide on developing DB requests for qualification and requests for proposals. It also assists the reader in interpreting these documents in order to prepare a responsive DB proposal or to evaluate a series of proposals and make a source selection decision.

Summary
Ponds (lagoons) have been used for centuries with great success in the treatment of wastewater. Ponds created for treatment, known as stabilization ponds, model the physical and biochemical interactions that occur in natural ponds. Easy to build and manage, stabilization ponds can accommodate large fluctuations in flow, and provide results that are comparable to conventional systems at a much lower cost. Wastewater Stabilization Ponds examines the use of this natural and highly effective process. The text is centered on wastewater pond management processes and operation procedures that provide passive treatment with a minimum of energy-driven mechanical elements.
It highlights the environmental principles, practices, engineering, and mathematics involved in the design and operation of conventional wastewater stabilization ponds. It also explores the major processes, procedures, and design methods relevant to wastewater treatment ponds. This includes the basic processes, in-pond design evolution and enhancements, oxygen addition, and modifications that require energy, nutrient removal, as well as effluent total suspended solids removal. Emphasizing the design, construction, and operation of wastewater ponds, the book serves as a valuable resource for anyone seeking information on pond construction and operation, knowledge of pond operation, and assistance in certification exam preparation and study.
> Presents a design of wastewater stabilization ponds
> Includes a complete description of pond process elements
> Provides descriptions of pond insect macroinvertebrates
> Incorporates pond morphometry calculations
> Contains extensive pond-related math problems
Sustainability and energy conservation are underlying themes throughout the text and the authors offer valuable information on potential renewable energy sources.

As society becomes more aware of the significance of the environment, such issues become increasingly important. The book exemplifies the vital role of environmental geology and geological processes in understanding the physical environment and the influence and fundamental importance of engineering geology in our modern world, particularly the infrastructure, whether it be foundations, routeways or reservoirs. The influence of geohazards, the significance of soil and water resources, and the impact of mining, waste disposal and pollution/contamination on the environment are all examined in this book. The various aspects of construction that are involved in the development of the infrastructure are also discussed - land evaluation and geological construction materials are therefore taken account of in this context. The book provides a wealth of practical examples and a comprehensive suggested reading list is provided for each chapter.

This significant new book by foremost experts in the field will be the first that truly covers the topic of engineering geomorphology as a distinct discipline and, as such, will be of paramount importance to both practitioners and students. Engineering geomorphology is concerned with the evaluation of landform changes, especially the effects of construction on the environment, notably on the operation of surface processes and the risks from surface processes, whether current processes or the legacies of past processes. Engineering geomorphology provides practical support for engineering decision-making (project planning, investigation, design and construction) and engineering geomorphologists form an integrate part of the engineering or environmental team. Engineering geomorphology has developed in the last few decades to support a number of distinct areas of engineering, including river engineering, coastal engineering, and geotechnical engineering, where engineering geomorphology has complemented engineering geology and has proven to be valuable, especially for rapid site reconnaissance and slope stability studies. Geomorphology provides a spatial context for developing site models and explaining the distribution and characteristics of particular ground-related problems (e.g. landslides, permafrost or the presence of aggressive soils) and resources (e.g. sand and gravel). Engineering geomorphology can also be applied to agricultural engineering, primarily in the investigation and management of soil erosion problems. This book includes basic concepts that underpin efforts to explain the causes, mechanisms and consequences of landform change. It then considers how the land surface works in the context of wetland, flatland, hills, mountains, rivers and coasts; and the techniques that are available to the engineering geomorphologist in the field, in the laboratory, in the office and in the various forms of remote sensing. Each succinct chapter is packed with vital information, well-illustrated with diagrams and tables and fully referenced so that the detail of subject matter can be followed up.

This monograph deals with buckling and postbuckling behavior of thin plates and thin-walled structures with flat wall subjected to static and dynamic load. The investigations are carried out in elastic range.
The basic assumption here is the thin plate theory. This method is used to determination the buckling load and postbuckling analysis of thin-walled structures subjected to static and dynamic load. The book introduces two methods for static and dynamic buckling investigation which allow for a wider understanding of the phenomenon. Two different methods also can allow uncoupling of the phenomena occurring at the same time and attempt to estimate their impact on the final result.
A general mathematical model, adopted in proposed analytical-numerical method, enables the consideration of all types of stability loss i.e.local, global and interactive forms of buckling. The applied numerical-numerical method includes adjacent of walls, shear-lag phenomenon and a deplanation of cross-sections.
