Anchor Bolt hole Sizes on Top Ring and Base Ring
Anchor Bolt hole Sizes on Top Ring and Base Ring
(OP)
PV Elite is used to design a vertical pressure vessel. It has passed the PV elite Calculations. However, PV Elite does not perform any calculations on the topring/ basering anchor hole size (just the anchor bolt size calculation).
I was told that typically the diameter of the anchor bolt holes in the top/basering should be 0.5in more than the anchor bolt diameter. In my case, I have 1.25" anchor bolt dia for 1.75" hole through the basering and topring.
However, the site has asked for 2" hole in the base ring and top ring instead of 1.75" hole so that they can match the anchor bolt locations in the foundation at site.
Can anyone provide guidance on what calculation needs to be done to check the adequacy of the anchor bolt hole in top ring/ base ring (not the anchor bolt calculation)? Reference to manual calculation or any design manual/ code would help.
Thanks.

Do you have any reference or calculation to size the washers?

Can you double check with your structural team member?
RE: Anchor Bolt hole Sizes on Top Ring and Base Ring
Bottom anchor bolt size to be bolt size + 19 mm
See PIP VEFV1110

How can Bolt diameter meet the criterion you say - "Bottom anchor bolt size to be bolt size + 19 mm".
Typo????
