The ninth edition of the best-selling Design of Reinforced Concrete continues the tradition of earlier editions by introducing the fundamentals of reinforced concrete design in a clear and understandable manner and grounded in the basic principles of mechanics of solids. Students build on their understanding of basic mechanics to learn new concepts such as compressive stress and strain in concrete while applying current ACI Code. The ninth edition has been updated to conform to the 2011 Building Code of the American Concrete Institute (ACI 318-11). Although written for an introductory three credit hour undergraduate course on reinforced concrete design, this textbook also has sufficient material for a second three credit hour course. This book is also useful for practicing engineers, as it presents the latest requirements of the ACI design code.
