Coefficient of friction
Coefficient of friction
(OP)
Should "design" or "ultimate" coefficient of friction be used to input into Code related load combinations?
A Code in mind also requires a SF of 1.5 after running the numbers.
I should add the the difference between the design and ultimate values is a factor of 1.5

RE: Coefficient of friction
(Presuming that you've adequately considered the coefficient of course. I think Caltrans has an adjustment factor for surfaces that might get wet that would end up washing out your 1.5 F.S.)
