This book provides answers to the following problems: how to identify the most probable critical failures; how to describe and use data-concerning materials that are either heterogeneous, time-variant, or space-variant; how to quantify the reliability and lifetime of a system; how to use feedback information to actualize reliability results; and how to optimize an inspection politic or a maintenance strategy. Numerous authors from public research centers and firms propose a synthesis of methods, both new and well-known, and offer numerous examples concerning dams, geotechnical study, and structures from nuclear and civil engineering.

Tractable Models of Solid Mechanics: Formulation, Analysis and Interpretation
Author: Oleg V. Gendelman, Leonid I. Manevitch | Size: 7 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: 2011 | pages: 307 | ISBN: 3642153712, 3642266622, 9783642153716
This book describes significant tractable models used in solid mechanics - classical models used in modern mechanics as well as new ones. The models are selected to illustrate the main ideas which allow scientists to describe complicated effects in a simple manner and to clarify basic notations of solid mechanics. A model is considered to be tractable if it is based on clear physical assumptions which allow the selection of significant effects and relatively simple mathematical formulations.
The first part of the book briefly reviews classical tractable models for a simple description of complex effects developed from the 18th to the 20th century and widely used in modern mechanics. The second part describes systematically the new tractable models used today for the treatment of increasingly complex mechanical objects – from systems with two degrees of freedom to three-dimensional continuous objects.

I am intrested in designing a integral abutment bridge/jointless bridge. Kindly help in calculating the soil spring value for wall and earth pressure distribution on solid wall type abutment and soil structure interaction. Please share any design reference, text book,journal or research paper on this subject.
More than one million people suffer from a slip, trip, or fall each year and 17,700 died as a result of falls in 2005. They are the number one preventable cause of loss in the workplace and the leading cause of injury in public places. Completely revised, Slip, Trip, and Fall Prevention: A Practical Handbook, Second Edition demonstrates how, with proper design and maintenance, many of these events can be prevented. This well-illustrated and carefully researched volume covers standards and best practices for facility design, effective management control programs, test methods and standards relating to pedestrian safety, and slip resistance methods in the U.S. and abroad. It includes checklists, handouts, case studies, rich online resources, and an extensive bibliography. See what’s new in the Second Edition: Enhanced photographs and tables, profiles of online resources, updated examples, case studies, and sidebars A new chapter on the unique hazards and controls to protect staff and patrons in food service A new chapter on known parameters and causes of patient falls, assessment methods, and methods for reduction of staff falls Discussion of flooring and floor maintenance, cleaning products and methods, outsourcing, and maintenance Coverage of management controls, a holistic approach to integrating slip/fall prevention controls into existing functions, hazard mapping, and electronic inspection systems Physical aspects of rubber walkways surfaces, expanded floor mats, new stairway statistics, visibility, and design Roughness measurements, perception of slipperiness, overseas standards, profiles of high risk industries, and accident investigation Contrary to popular belief, most slips and falls are not due to carelessness. This Handbook examines the many options available in the design and maintenance of facilities that can reduce or eliminate the potential for slips and falls.

Author: S. Pompeu Santos | Size: 6.2 MB | Format:PDF | Quality:Unspecified | Publisher: Taylor & Francis | Year: 2006 | pages: 213 | ISBN: 0415425778, 9780415425773, 0203947037
Enclosure walls have a key role in building construction, providing structural safety and protecting interiors from intrusion. The concept of an enclosure wall is a traditional one, common to the building history of many countries. There is a tremendous variety in types of enclosure walls, depending on such variables as climate and local technologies. Progress in these traditional practices has been stimulated by new national and international standards in the construction industry. These standards have contributed to improvements in areas such as thermal insulation and earthquake resistance and have promoted the development of new materials and methods in enclosure wall construction. The aim of this book, by the Commission on Wall Structures of the International Council for Building (CIB), is to select certain countries or regions, and examine enclosure masonry walls which are perceived as being typical. For each example, the following are considered: characterization of the building sector; the customary materials used in masonry; typical problems and solutions for enclosure walls; and evolutionary trends.

This British Standard specifies performance requirements, including requirements for durability, for water repellents intended for use on
masonry above ground level and free from cracks with a surface width exceeding 0.15 mm.
Water repellents are classified into four groups according to suitability for use on particular types of substrate. The various clauses in the specification containing performance requirements refer to
Appendix A to Appendix H inclusive. These appendices contain test procedures, which are also requirements of the standard.
Appendix J gives recommendations for use, covering general considerations, the preparation of surfaces to be treated, the application of the repellent and the protection of workers.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.

Presents a cohesive and comprehensive understanding of water-retaining structures' construction in order to build with speed and economy. Contains numerous worldwide examples, many of which are based on existing structures as well as extensive tables related to the analysis of rectangular, circular and conical formations in order to develop good working practice. Also features practical diagrams, computer programs, listings and a useful appendix which covers the analysis of ground-supported open circular concrete tanks.
