Catenary Strutures

Catenary Strutures 

Arches in the Casa Mila
Caternary by definition is the name for a curve that occurs naturally when a chain of uniform density is allowed to hang. It comes from the Latina term "catena", which means chain. 

Catenary is used in mathematics, often to find a function to represent a particular shape or situation. In history, Galileo was the first to study a catenary, but he mistaken the identified shape as a parabola. He believed that a hanging rope created the shape of a parabola.

Antonio Gaudi was a Spanish artist/architect and he said "There are no straight lines or sharp corners in nature." He designed an apartment building in Barcelona called Casa Mila which was very unique. In the apartment building there are catenary arches.

In Casa Mila, there is a sculpture of hanging chains on the top level.  Since chains naturally form the shape of a catenary, it displays many catenaries in one sculpture.


Here are examples of other catenary arches:
