Designed by Leslie Robertson in 1966 to be the tallest, most innovative buildings in the world. Floor Plan Innovation: Most of the columns in the skyscrapers were placed around the perimeter of the buildings. Very strong, designed to resist wind. Was in fact able to withstand the shock of the plane flying into it. Other columns placed in a group at the center; connected to outer wall columns by ‘floor trusses.’ ------------------------------------- | | | | | | | | | -------------------- | | | | | | | | | ------------------------------------- floor plan. Impact Tower 1 (North) Problem with sheetrock used to insulate off the center columns: Not very physically strong. Were destroyed at level of impact and exposed escape stairs to fire. Could have used concrete? Maybe people could have gone down stairs. Example of weakness of sheetrock. Crash caused elevator to jam. 6 people trapped. Used window-cleaning squeegee to break drywall. Also: spray- on fireproofing blown off steel floor trusses, which melted.
