Shape Of the Eiffel Tower

Description about Shape of the Eiffel Tower

The third floor is the Eiffel Tower at night, seen from the Trocadero. At that time the tower was built many people were shocked by its daring shape. Eiffel criticized for design and accused of trying to create something artistic, or inartistic according to the viewer, without regard to technology. Eiffel and his engineers, but as well-known builders of bridges, understood the importance of wind power, and knew that if they plan to build the highest structure in the world, they must be confident that it will withstand wind

The shape of the tower is therefore determined by mathematical calculation involving wind resistance. Several theories of this mathematical calculation was proposed for many years, the latter is a nonlinear integral equation based on counterbalancing the wind pressure on any point on the tower with the tension between elements of the design at this point. This form is exponential. Careful site tower curvature however, reveals two different exponentials, the lower section with a strong resistance to wind forces. But not structural elements are the four decorative arches and grillwork, was added to the sketches Steven Sauvestre, which served to assure users that the structure was safe, and to develop views of other nearby architecture.
