Infinite and Finite Fatigue Checks
Infinite and Finite Fatigue Checks
(OP)
My friends,
When should one consider Fatigue 1 and when Fatigue 2?. It is just not clear to me. Textbooks adopt different approaches and can be quite confusing. For the same ADDT(SL) of 6800 (200000x0.2x2x0.85 based on a 2 lane rural intersates simple span stel beam-slab), some texts will go ahead with Fatigue 2 and some will try Fatigue 1.
Thanks in advance

RE: Infinite and Finite Fatigue Checks
Fatigue II is based on AADT and finite life.
RE: Infinite and Finite Fatigue Checks
could you be more precise?. I understand from your statement and from what I have read that Fatigue II is the design criteria. It must always be checked. But if fatigue I, which is not a criteria, is satisfied, then Fatigue II is satisfied by default. Is that what you are saying?
thanks in advance
