Notes
The One World Trade Center was built at the site where the Twin Towers
were destroyed on September 11, 2001. The tip of the antenna will reach
a height of 1776 ft - a figure symbolic of the 1776 United States Declaration
of Independence. The antenna mast consists of multiple 40 ft long
segments with a different type of steel load-bearing structure, each suited
for a corresponding type of antenna. The complicated transition zones
between the segments were designed with cast steel elements in accordance
with the load transfer. Due to design reasons, the antenna is
cladded with glass-fiber reinforced plastic sandwich elements. During the
wind tunnel testing, transverse oscillations were observed, which have
been avoided through spirals along the cladding. To limit the deformations
due to wind, the antenna is guyed by Kevlar cables. We were commissioned
for the structural design of the antenna as well as for the cable net
walls at the foyer and other glass structures.
