Coefficient of friction value
Coefficient of friction value
(OP)
What value would be suggested for the coefficient friction between a horizontal steel tank and its pier craddle lined with asphalt felt.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

You might want to run your own tests...
RE: Coefficient of friction value
I think Mike is right you'll have to do some testing if you really want to know a value. I assume the 15# or 30# felt, or layers thereof, were put there to absorb some irregularities in the bearing/mating surfaces btwn. the pier cradle and the tank. Temperature and bearing pressure will cause the felts to bond to each other and to the steel tank and the concrete saddle, and the failure mode will be a shearing failure or flow in the felt thickness. I've seen and done things like this in the past and just assumed there could/would be some movement or flow in the bearing material layers without over stressing the steel tank or conc. saddle, but never really had numbers to put on it.
