520			_aThis book is suited for a first course in prestressed concrete design offered to senior undergraduate students in civil engineering and postgraduate students in structural engineering. The book focuses on the behaviour of the prestressed concrete structural elements. Carefully chosen worked examples are included to delineate the design aspects while relevant chapter-end questions enable effortless recapitulation of the subject. The content, while being useful to both the students and teachers, will also serve as an invaluable reference for engineers.
