Contemporary architecture in recent decades has been developed in the most varied types of buildings. From bank headquarters like the one designed by Norman Foster in Hong Kong, airports like the Kansai airport in Osaka or viewpoints like the new Dubai Frame. And of course architecture has also entered a kind of maelstrom to create the most spectacular structures. And to see examples you don't have to look at what is being built in the most recent years of the 21st century. This spirit is also found in the last century, for example in the Gateway Arch of the city of San Luis in the United States.


St. Louis Getway Arch

We are in front of a construction inaugurated in 1965. A gigantic commemorative monument with which they wanted to pay homage to Thomas Jefferson, and above all to the role that this American city played in the development of the country towards the lands of the Wild West.

The monument was the subject of an international competition, and the winner was the architect Eero Saarinen, from the United States but originally from Finland.

This is a grandiose arch-shaped gate that reaches 192 meters in height and is spectacularly visible from the banks of the Mississippi River. But it is not simply a monumental arch that frames, for example, the Palace of Justice of the city or thatit links to the Eads bridge over the river, from which it takes its tubular steel structure.

In addition to that, the Arc Gateway has several spaces inside, and also in its basement. There's the Westward Expansion Museum, as well as movie theaters. And then the entire arch is traversed in capsule-shaped elevators that lead to a fantastic viewpoint over the city.

As we have already said, the entire construction is made of steel, logically stainless on the outside. Which is presented in plates in the shape of equilateral triangles that allow it to be curved, since they become smaller as the structure gains height. While inside, and without contact with the open air, the chosen materials were concrete and steel, but now carbon.

And also the two bases of the arch are in the form of an equilateral triangle, supported by foundations that sink to almost 19 meters deep. Considerable dimensions that support the weight of the entire structure, but that are also conceived and designed to withstand earthquakes and especially strong winds. In fact, calculations indicate that the St. Louis Arc Gateway could withstand winds well in excess of 150 miles per hour, as it is designed with a tilt capacity of up to 9 inches.
