Fundamentals of Reinforced and Prestressed Concrete

Fundamentalsof Reinforced andPrestressed ConcreteByDIPL. ING. M. HILAL DR. SC. TECHN.PROFESSOR, FACULTY OF ENGINEERINGCAIRO UNIVERSITY, GIZA2005 PREFACEStructures should be designed and constructed to fulfill safety,economy and efficiency. When dealing with reinforced and prestressedconcrete structures, the designer is facing a combination of two to-tally different materials, concrete and steel, behaving in a verycomplicated manner. A rigorous treatsent of the inelastic, discontinuous, time-dependent behavior of concrete reinforced by steel is virtually an impossibility. However, extensive research in the field ofreinforced and prestressed concrete yielded a good understanding oftheir behavior and relatively simple theories…
