UG-101 revision

(OP)
Does anyone remember when the safety factor changed from 5 to 4 in UG-101? Did it coincide with the changes in allowable stress that came with the 1999 Addenda? Thanks for dusting off the memory banks...

RE: UG-101 revision

You mean the change from TS/4 to TS/3.5.

RE: UG-101 revision

and it was the 1999 Adenda.

I was actually wondering about the change in safety factor for rate by burst, in UG-101. I could see how it could be related to the 1999 change in safety factor vs ultimate, but was not sure they happened at the same time. Thanks for the responses...
