• Gebundenes Buch

Produktbeschreibung

Foundation Engineering focuses on the analysis and design of foundations using rational approaches to a large extent. Soil-Structure interaction approach using Winkler model for soil representation is discussed in detail along with conventional approach. It also presents the structural design methods using codes of practice for limit state design of RC structures. Analysis and design of commonly constructed shallow foundations as well as circular and annular foundations have been presented in detail. Pile foundations subjected to general loads and moments are discussed in detail.

In Foundation Design: Theory and Practice, Professor N. S. V. Kameswara Rao covers the key aspects of the subject, including principles of testing, interpretation, analysis, soil-structure interaction modeling, construction guidelines, and applications to rational design. Rao presents a wide array of numerical methods used in analyses so that readers can employ and adapt them on their own. Throughout the book the emphasis is on practical application, training readers in actual design procedures using the latest codes and standards in use throughout the world.
Presents updated design procedures in light of revised codes and standards, covering:
American Concrete Institute (ACI) codes
Eurocode 7
Other British Standard-based codes including Indian codes
Provides background materials for easy understanding of the topics, such as:
Code provisions for reinforced concrete
Pile design and construction
Machine foundations and construction practices
Tests for obtaining the design parameters
Features subjects not covered in other foundation design texts:
Soil-structure interaction approaches using analytical, numerical, and finite element methods
Analysis and design of circular and annular foundations
Analysis and design of piles and groups subjected to general loads and movements
Contains worked out examples to illustrate the analysis and design
Provides several problems for practice at the end of each chapter
Lecture materials for instructors available on the book's companion website

Foundation Design is designed for graduate students in civil engineering and geotechnical engineering. The book is also ideal for advanced undergraduate students, contractors, builders, developers, heavy machine manufacturers, and power plant engineers. Students in mechanical engineering will find the chapter on machine foundations helpful for structural engineering applications.
