The methods in design of reinforced concrete are changing as the technology is progressing; consequently the codes of practice have to be updated frequently when compared with the other methods of construction. The Indian Code of practice on Plain and Reinforced Concrete, IS: 456 that is considered to be mother code for design and construction of concrete structures has gone through the fourth revision and now being implemented in India. The revised edition of the book is based on the revised code of practice, IS: 456-2000. The section on the durability of concrete structures is expanded considering the latest trends in the durability-based design of concrete structures and the code specifications. A section on quality assurance in concrete structures is added incorporating the acceptability criteria of concrete as per the revised code of practice. A brief note on Nondestructive Testing of Concrete Structures is included considering the latest technology in quality control. The Limit State Design of concrete structures was originally introduced in Indian practice in 1978 along with Working Stress Design method. However the present revision of the code has given more importance to the Limit State Design. The book therefore covers the limit state design method extensively with a number of examples. Reinforcement detailing is another important aspect, which often neglected leading to poor quality and reduced life of the structures. All examples are accompanied by illustrative drawings giving a depth to the understanding of the subject. The chapters on yield line theory of slabs, design of reservoirs and overhead water tanks, and design of shallow and deep foundations are given special treatment considering the needs of the consulting and practicing engineers. The chapter on miscellaneous structures covers some unusual designs not normally available in many books. The author has incorporated his vast experience in teaching and wide consulting practice in the book with practical applications. The book is intended as a textbook for Civil Engineering students and a reference book for practicing engineers.
