Resum
The safety of partially prestressed bridges has been a matter of some concern since the fretting fatigue phenomena was discovered in the mid-1980s. This phenomena is not easy to assess due to the random nature of variables influencing fatigue. In this paper, reliability methods have been used to assess the overall safety against fatigue of a wide range of partially prestressed concrete highway bridges. Safety against fatigue is represented by a reliability index (probability of failure) calculat...
