ABSTRACT
Preliminary note: For class teaching, it has been found very effective to use the following C and CA booklet as a supplementary text: A . H. Allen, (A n Introduction to Prestressed Concrete’, supplied at low charge by the C and CA to universities and colleges. Students should be asked to read, in their own time, A . H. Allen's booklet, particularly the excellent descriptive chapters on prestressing methods, materials and equipments. The class lec tures would then follow Chapters 9 and 10 o f this book as the main text.
