I remember O'Neill suggested 1/2 pressure with twice the percentage of

Are you saying that might be a mistake?

If your structure is strong enough to support radiation shielding, it might
be strong enough to handle sea level air pressure. If you can produce a lot
of either iron or aluminum from local resources, then you can use a fair
amount of metal in your structure. I wonder if pure oxygen would cause iron
to corrode faster.
