Abstract

In summary some general comments can be made about prestressed concrete in fire. The main problem is the amount of cover required to protect the steel from reaching excessive temperatures. This is also the main problem for reinforced concrete. The other problem is restraint. It could not really be said that prestressed concrete behaves better than reinforced concrete. The prestressing strand however is more susceptible to temperature rise due to its properties. It is surprising that no where in the references used was there anything to indicate the importance of temperature effects on bond. However mention was made about the research required to enable better understanding of this. In general the research done has proved that fire resistance of prestress concrete is excellent.
