## Abetract-Warm prestressing, by which structural steel can endure stress without lowtemperature brittle fracture after it has previously been exposed to the same stress at a higher temperature, contributes to the effectiveness of preheating in increasing the weldability of steels. It has also be

A fracture mechanics approach has been used to predict the approximate extent of cracking in a prestressed concrete pressure vessel subject to overpressure. The stress intensity factor has been calculated by means of the crack closure work concept and finite element stress analysis for a range of cr
## Abstract For an assessment of the risk potential of existing structures, where in the case of prestressing steel damage the loadβbearing capacity could be significantly affected, nonβdestructive testing techniques which enable reliable evaluation of the condition of the prestressing steels are o
