Prestressed Concrete Structures, (Paperback)

The book is designed to serve as the first course for civil engineering students and a guide to design engineers. It is an outcome of more than 25 years of teaching of the subject to IIT Kanpur students and experience of field problems. Three basic methods of design, namely Working Stress Design (WSD), Limit State Design (LSD) and Ultimate Strength Design (USD) which are in practice are dealt with. The Limit State Design being the latest, very extensive presentation of the method applied to fully and partially prestressed concrete structures is made. An introduction to the probability failure analysis leading to the limit state concepts is illustrated along with some statistics of observations. Full and partial prestress designs based on the latest codes of practice are explained with a number of examples on variety of elements, such as beams, ties, columns, slabs, shells and bridges. Detailed design examples on minimum weight design of beams is presented to enable the students and designers to look for rational solutions. Cost analysis of components of materials and formwork in beams is illustrated. Some of the key features of the book are:

1.            Discussion on limit state design of full and partial prestressed concrete beam.

2.            Detailed examples of design of small to long span beams, water tanks, cylindrical shells, folded plates, domes and bridges are illustrated.

3.            Latest codes of practice are incorporated and comparison of the designs based on different methods and illustrated.

4.            Economical analysis and the influence of design variable and methods on cost are discussed.

5.            Useful design aids for beams, cylindrical shells are given in appendices.

6.            A set of objective questions which will enable a student or an engineer to find most rational solutions and concepts are listed in the appendix.

Dr. Pasala Dayaratnam, Ph.D. (1962) in Civil Engineering, University of Colorado, Boulder, USA joined IIT Kanpur in 1965 after teaching at Andhra University, Waltair with brief experience in Andhra Pradesh PWD. He taught variety of subjects at undergraduate and postgraduate levels both at Andhra University and at IIT Kanpur for about 30 years, guided research students and a number of sponsored research projects. He has been a consultant in design of complex industrial structures, tall buildings, towers, bridges and shell structures. As a member of Bureau of Indian Standards Committees, he is associated with development of many codes of practice in structural engineering. He has experimented on teaching methods, evaluation procedures and testing sequences. He authored nine textbooks in structural engineering, 110 research papers and about 150 reports on design, testing and evaluation. Dr. Dayaratnam is a recipient of awards during his entire student career from high school to Ph.D. level and some of his research publications have also won awards.
