Resum
A method for the fatigue reliability assessment of post-tensioned concrete bridges is applied to a wide spectrum of highway bridges covering over the most commonly built with this technique. The objective is to obtain the fatigue performance of reinforcing bars and prestressing strands. First, bridge geometry and properties are defined, and different degrees of prestressing are considered. The reliability indices are worked out for ultimate limit state (ULS) of fatigue and bending and for heavy ...
