Eiffel Tower
A famous Paris landmark and
masterpiece of wrought iron technology. It was erected in 1889
for the exhibition celebration the 100th anniversary of the
French Revolution. The French engineer, Alexandre Gustave
Eiffel based his design for the Eiffel tower on his experience
with building high-level railway bridges. From a detailed set
of plans the 12,000 metal parts of the tower were all
prefabricated and numbered for assembly. The majority of the
2.5 million rivets used were in place before the structure was
erected on the site. The gigantic undertaking proceeded so
smoothly that not one worker' s life was lost by accidents on
the scaffolding. The tower was completed except for the
elevators in 26 1/2 months.
The Eiffel tower is designed
as a cross braced lattice girder that offers minimum. wind
resistance. The estimated movemen of the structure with
hurricane force winds is only 8.8 inches. 1t is constructed
from over 7,000 tons of the highest quality wrought iron,
resting upon four 25 sure foot masonry piers. The pieces are
set in 7 feet of concrete far below ground. The height of the
tower is 1056 feet.
