In one of the vessels supported by Lug Brackets, i have noticed that the Anchor Bolt area calculation due to uplift has been performed in empty condition. Should not it be done in Operating condition (conservative) considering the Moment and operating weight. My PVElite elite file 2007 version.

I do not know if there is change in calculation in later versions (2008 or 2009 and updates). Can someone clarify ?

The program tries to find the most conservative load combination,

Wind + empty condition

Earthquake + operating

etc.

to find the most severe overturning condition and as a results has largest anchor bolt load.

You should strongly consider upgrading to the latest version of PV Elite, the codes/standards change all the time, we also add many new features and fix problems as we find them.

It is not worth the effort if you are caught using an older code rules.
