Tower Core
Did you know that the Twin Towers have a soul? Both as a super reinforced that goes from the bottom up?
This will help me in my personal research No, not part of my job.
Built by the Port Authority of New York and New Jersey in early 1970, the World Trade Center were for their time, examples tube known buildings. Tube buildings are reinforced by closely spaced columns and beams on the exterior walls. The columns and beams closely spaced in each tower form a steel tube, with an inner core, withstand enormous wind loads that affect buildings of this height. In addition withstand winds of huge World Trade Center towers were also built for the costs of resolution resist. Because the towers were constructed in six acres of landfill, the foundation of each tower, would extend 70 feet below ground level to rest on the rock.
