Prestressed Concrete: theory and practice
Luiz Cholfe , Luciana Bonilha
This book aims to introduce the fundamental sizing and verification concepts of prestressed concrete structures. The text covers the program of graduation courses and also includes a brief revision of items from pre-required subjects, such as General Mechanics, Strength of Materials and Reinforced Concrete.
The theory presented is based on the recommendation of the Norma NBR 6118 (Project of Prestressed Concrete Structures), complemented with numerical applications of examples taken from professional practice.
The book covers, in six chapters, the following subjects:
- Materials, concepts and operation principles of prestressing;
- Comparative study between pieces of reinforced and prestressed concrete, types of prestressing as to the building processes and the demands relative to cracking, methods of Limits States and security in structures;
- Verification and sizing of the prestressed concrete cross sections;
- Sum of prestressing losses;
- Revision of concepts and perquisites, [macroscript?] for projects of prestressed concrete structures and geometrical layout of cables;
- Solved exercises.
This book may be used as didactic material in graduation and specialization courses and by professionals who work in the field of Projects and Execution of Prestressed Concrete Structures.
