ABSTRACT
This chapter primarily focuses on the design of simply supported prestressed beams, which are commonly used in the construction of bridges, parking structures, and other types of buildings. These beams are designed to withstand bending and shear forces by using high strength steel strands or bars. The design process involves selecting the appropriate prestressing force and profile, as well as determining the most adequate cross-section of the prestressed element.
In addition to simply supported prestressed beams, this chapter also covers the design of composite girders, which are composed of prestressed concrete beams and a reinforced concrete deck. This type of construction has several advantages, including increased strength and stiffness, reduced deflection, and improved durability.
