A Case for Partial Prestressing

Part of the book series: Institut für Baustatik und Konstruktion ((IBK,volume 41))

Abstract

The broad field of partial prestressing between reinforced and fully prestressed concrete is described. In particular the use of post-tensioning cables in combination with ordinary reinforcement is investigated. The advantages of such a combination, which include constant safety, greater economy, and control of deflections, are mentioned.

In the design an appropriate selection of the two reinforcements has to be made, taking into account the relation between dead load and live load, the required safety against ultimate load, the deflection due to creep and shrinkage under permanent loads and consideration of fatigue. The stress calculations at working loads are mentioned.
