that's it?The columns in the core would be connected with horizontal beams to other columns every 12 feet of height but the bolts at the end of box columns are really important even though H beams would be used closer to the top though we don't know where the switch from box to H beams took place. May have varied with each column.
The perimeter was box columns from 9 to the top.

that's all you have to say about these butt joints we have been telling you about?
and it isn't just the core columns, a third of the perimeter was butt joints.
how is this going to affect your model?
