I'll change the design:
Suppose we have this dome and we add a cylinder to the
base. So 50 meter hemisphere sits on top of say 10' high 50 meters in diameter pipe.
We will make the pipe strong enough to withstand 5 psi
and it will have 40000 strength yield steel.
Wall thickness needs to be 0.1230

We will made it .250" or 1/4" steel.
So 50 meter diameter is 157 meters in circumference.
Or 515 feet. Times 10 is 5150 sq ft.
There are 48 1/4" in 1 foot, so 5150 sq ft is equal to
32.7 cubic feet of steel. At 487 lb per cubic feet=
15,925 lbs. [Weighs 1/3rd of this on Mars]
We put this cylinder on some flat spot on Mars.
We get front loader to dump into the cylinder
4' of martian dirt. Level it. And pack it down.
Getting it all ready to put in a sod grass lawn.
Put the dome on top of cylinder. Secure and seal it.
On outside make stairs go up 4 feet and put a door in the steel pipe wall.
Pressure dome to 1 psi.
Lay sod, and water it.
So I need someone to give safety inspection before
pressurizing it to max of 5 psi.
What could be the recommendations?
Such as:
Is a moot because at 1 psi it's already flown away or exploded in some manner?
Should concrete be attached to outside pipe wall with metal fasters which tied into rebar reinforce concrete collar which amounts to thousands of tonnes in weight?
Get rid of stairs, grade dirt up to door level and put in some nice paving stones to the door.
Would it be different if instead of Mars this was done on Earth?
