You are actually comparing stairwells to core supports? Why? Stairwells were drywalled in several plies held up by less dense steel beams. They had nothing to do with the core supports. The core supports surrounded everything placed inside the core. They were not holding up drywall on the stairwell walls.
Could it be that those of us actually living in the physical world have spent our entire lives, observing and learning from the physical in which we have resided, some us far longer than others?
From whom or where did you get that 30% data? From some hearsay report(s)? Or were you in the buildings examining and calculating all that, from up close and personal examination, before the buildings collapsed?
I agree with others you are wrong.
There is no factual evidence of what you are stating from NIST or anyone else.

The stairwells were within the area of core columns. It's a reasonable observation that if multiple stairwells were destroyed then the core columns suffered also to an unknown extent.
"At 8:45 a.m., Walter Lipiak had just unlocked the door to Cosmos Service America on the 89th floor of the north tower. . . he gathered them up and herded them toward the stairwell, which was locked. Police arrived, unlocked the exit, and Lipiak's people joined what would become a throng on the route down.
"87th floor of One World Trade Center...They began an odyssey down the crowded stairwell. At one point, they had go back upstairs to reach another stairwell because they couldn't get past a locked steel door."
"Anyway, in the story, Andruzzi says: "We get to the fourth floor, and the door out of the stairwell to the lobby is locked."..."
"...Pushing frantically on the locked stairwell doors of the World Trade Center, Frank Joseph Doyle made a call to his wife, telling her that he and others were trapped and she should dial 911...
""Eventually, as we got closer, to about the 16th floor, it started to move. The last six floors, there was water pouring down the stairwells. We got to the mezzanine and had to walk down the escalators from there to the main lobby, which had 6 to 8 inches of water...
..."It struck Heineman afterward that everything would have been worse an hour later. The offices, like his own, would have been filled. The stairways would have been impassable...."
"When Baumbach and the knot of people behind him made it to ground level, they could not go through the doors because of the smoldering debris that was crashing down. They were sent down a stopped escalator to the underground Plaza Level and the WTC mall and that's where - an hour into their frantic flight - they found themselves wading through pitch black surroundings in a foot of water:..."

Each tower had three stairwells within the core structure. In one tower, all three stairwells were damaged to the point where people above that section could not get down, the other tower two stairwells were damaged to the point of impassability. Sorry, but that just does not happen WITHOUT damage being caused to the core. I know you wont accept that

Not reasonable at all, the stairs were not like the columns at all. The stairs would have been exposed between the columns and made from far lighter thinner metal.
