AASHTO LRFD 2009 Fatigue Question
AASHTO LRFD 2009 Fatigue Question
(OP)
One of the major changes to AASHTO LRFD 2009 Design Specifications was the doubling of fatigue loading in "infinite life" cases. Because of this, a plate girder bridge that I am designing that met all requirements in AASHTO LRFD 2008 is now failing miserably in fatigue in 2009. Is anyone else having this experience in design?
