WisDOT Bridge Manual Chapter 19 – Prestressed Concrete
Simple Span Prestressed Concrete Beam The horizontal component, P, of the tendon force, F, is assumed constant at any section along the length of the beam. Also, at any section of the beam the forces in the beam and in the tendon are in equilibrium. Forces and …
Flexural Strength of Reinforced and Prestressed Concrete …
For non-prestressed reinforcement, stress in the reinforcement below the speciﬁed yield strength fy for the grade of reinforcement used is taken as Es times the steel strain. For strains greater than that corresponding to fy, stress in the reinforcement is considered independent of strain and is equal to fy.

Reinforced and prestressed concrete are used extensively in bridge projects. In addition to general design guidance and information on detailing practices, this section contains three design examples a three-span reinforced concrete slab superstructure, a 63 inch pretensioned I-beam, and a three-span post-tensioned concrete slab superstructure.
Prestressed concrete - Wikipedia
Prestressed concrete. Prestressed concrete is a form of concrete used in construction which is "pre-stressed" by being placed under compression prior to supporting any loads beyond its own dead weight. This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete volume,...

What is prestressed concrete? - Quora
What is prestressed concrete? How is it used? Before getting into prestressed concrete, let us go back to the basics first. We all know that concrete is strong in compression and weak in tension. This is reason for providing reinforcement (in the form of steel bars) to resist tension/tensile force acting on beams/columns/slabs etcetera.
