Structural details of the core truss system in the twin towers, from drawing Book 9


Is there a FOIA#?

This is a long term ongoing

This is a long term ongoing request for drawing books and in particular floor truss details. So far it's confirmed the truss core ends were not accurate as per NIST's ANSYS model via some Laclede details, and also is assisting to quantify the elements removed from their main model (strap anchors, bridging trusses, shear studs etc).
