Strengthening prestressed concrete with prestressed CFRP
Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2009This paper presents the effect of unevenly prestressed carbon-fibre-reinforced polymer (CFRP) sheets used for strengthening a prestressed concrete beam (L = 3·6 m). An integrated anchor system, consisting of steel brackets and anchor plates, is used to prestress the sheets.

Prestressed Concrete Flat Slabs
1977A short review on the analysis and the design of prestressed flat slabs is given. Some new aspects concerning flexural behavior, punching, reinforcement arrangement and detailing are presented. Different possible tendon layouts are compared. A new model for slabs with unbonded tendons and additional reinforcement is described.

Prestressing Optimization of Concrete Slabs
Journal of Structural Engineering, 1991An algorithm to minimize prestressing steel in concrete slabs is presented; it is based on elastic theory and uses the finite element method. The influence‐line method and the equivalent‐load approach are reviewed and the latter is employed to compute the effects of prestressing.

Prestressed Concrete Applications
2018Prestressed concrete is adaptable to a wide variety of structural systems. These include pretensioned and post-tensioned structures, both cast-in-place and precast, and other prestressed elements in conjunction with normally reinforced concrete.

It is presumed that the reader is familiar with the basic physical properties of portland-cement concrete, which is the principal constituent of prestressed concrete. It is important that a proper concrete be employed in prestressed concrete construction, but only the factors that are of particular interest in this type of construction are considered ...

Overview of Prestressed Concrete
2016Concrete has a considerable compressive strength, but its tensile strength is quite limited. Thus, designers use reinforcement in conjunction with concrete to make useful elements in buildings.
