What I mean is, if my floors could withstand 80PSI and my tank came out to 80PSI on its foot print, would I be ok? Or should I brace it just in case? Those numbers are arbitary(sp).
You mention wood memory, does the engineerd "I" beam joists have the same property? You know the 2x2's with the OSB webbing.
Yes it would be safe to say that to a point. You could use those figures to figure if you need bracing but You would not want to put 100% load capacity. There would need to be a safety margine. Was the safety margin figured into the load capacity? Codes are also going to differ on this. there is not a definite answer I can give you.
On the second question, no the I-beam systems are not going to have the same properties as standard pine. OSB is a composite wood that will take on the properties of both the wood and the bonding material.
My point is that I would not be worried with the OP's situation. I dont really consider a 180 that large of a setup. I'm pretty confident that he will not have issues asspecially since its not out in the middle of the floor. Besides we don't even know what kind of floor its on. No need to get worried over nothing. The demensions of that tank lend well to distributing weight over the joist.
