Section VIII, Div.1, UG-39
(OP)
If a bolted flat head with multiple openings is reinforced per UG-39(e)(2), does it also have to be reinforced per UG-39(d)(2)?
My thinking is that UG-39(d)applies to flat heads with a single opening, while UG-39(e)applies to flat heads with multiple openings, so it seems to me that only the UG-39(e) reinforcement would be applicable and would be added to the required thickness from UG-34(c)(2).
THANKS

RE: Section VIII, Div.1, UG-39
I have another application that is similar, except that it is being designed to ASME Section I. It appears to me that the ligament section of PG-52 is different from the reinforcement requirements in Section VIII in that it does not use an 'h' factor, just a ligament efficiency. In this case, would the flat head thickness from PG-31 be divided by the ligament efficiency to determine the total reinforced thickness requirement?
I appreciate any input you can provide.
Thanks,
