The high yield steel was used because, I assert, using A36 steel would have required thicker plates, add more dead load all the way down making the wall thickness of the lowest columns too thick even to join them because there would be no void inside for the bolts. The facade columns were limited in OAL dimension unlike the core columns. The higher yield steel was stiffer apparently and this was part of the wind shear strategy for the top most floors.Oh, but I did explain it in detail and you repeated most of my explanation. Your complaint has no legs and the only thing your post here shows is that your comprehension is poor, although that doesn't necessarily have to be unintended.
