It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service. University of Liverpool. PRESTRESSED CONCRETE. 1. Ar.C.N.Vaishnavi Ar.M.Padma Reinforcement • Concrete is about 90% weaker in tension than it is in compression • Steel has high tensile strength, has the same thermal expansion as concrete, and bonds well with concrete Reinforced Concrete • Reinforced concrete is a strong durable building material that can be formed into many varied shapes and sizes. The prestressing tendons are typically un‐sheathed so that the concrete bonds to the tendons. CE549 Bridge Engineering I Spring 2006 SCOPE: This course will present a modern approach to highway bridge analysis, design and evaluation based on the American Association of State Highway and Transportation Officials LRFD Bridge Design Specification, 2004 edition (with 05 and 06 interims). Recently the limit states design method, which appeared in the last century and has been already applied in the design of buildings, bridges, etc, is proposed as a better method for the design of prestressed concrete sleepers.

Jackson was granted the first patent in the United States for prestressed concrete design. A plane section before bending is assumed to remain plane even after bending, which implies a linear strain distribution across the depth of the member. Prestressed concrete in which tensile stresses in the concrete are entirely obviated at working loads by having sufficiently high prestress in the members.
