This book is suited for a first course in pre-stressed concrete design offered to senior undergraduate students in civil engineering and postgraduate students in structural engineering. The book focuses on the behaviour of the pre-stressed 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.
