I haven't heard anyone here say the y believe it is the ark ! ...And for that very reason, my OP was posed as a question.
Even National Geo did not simply pass off the discovery as some kind of publicity stunt. They too asked the question. ..And please note they didn't seem to question the structure's existence, and at that elevation.

The photos are about a decade old, and comments have been made each way
can only add other questions...
A) Unlike other very high mountains, such as Mt Everest, Denali, The Zugspitz, K2 etc, are among other mountains, simply rising above their neighbors. Ararat rises almost alone from the plains, to about 16, 8900 feet, so it is a tough climb for any human or animal.
B) There are some huge timbers involved in the structure, which is at over 13,000 feet. Just how easy was it for man or animal to haul those timbers that far up the mountain, and for what reason?
C) the description seems to point out long halls with compartments. If so, it wouldn't likely be a shed to store air ships, and the elevation precludes submarine pens. Professional offices perhaps..or a mini-mall ?
D) Seriously though, what are the chances, that either humans or animals carried those timbers to that elevation?
E) A large wooden structure could e elevated to that height by a massive flood however. ..But we have heard that story before, and many scoff at the possibility of such a flood.
F) Finally, I only offered the piece as a mind exercise, we really should not decide to simply pass such things off as a fraud, without at least taking a look.
I try to keep a reasonably open mind to such things, even though most such "discoveries", turn out to be false.
Before Barnum had a circus, he did have a travelling rare animal show. There is a story which says... One day he brought his show to a small, rural Kansas town. The local folks toured the show and enjoyed the animals, such as would not normally be found in Kansas.
One farmer. likely less read than most, suspiciously approached the cage where a giraffe was kept. After closely observing the giraffe for some minutes, he declared.."There ain't no such animal"!
The moral to the story, for me...
Just because something seems improbable to me, that doesn't mean it is impossible.
