Arch

An arch is a curved structure that spans a space and may or may not support weight above it. Arch may be synonymous with vault, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the Ancient Romans who were the first to apply the technique to a wide range of structures.

Basic concepts

An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses and, in turn eliminating tensile stresses. This is sometimes referred to as arch action. As the forces in the arch are carried to the ground, the arch will push outward at the base, called thrust. As the rise, or height of the arch decreases, the outward thrust increases. In order to maintain arch action and prevent the arch from collapsing, the thrust needs to be restrained, either with internal ties or external bracing, such as abutments.

Gateway Arch

The Gateway Arch is a 630-foot (192 m) monument in St. Louis in the U.S. state of Missouri. Clad in stainless steel and built in the form of an inverted, weighted catenary arch, it is the world's tallest arch, the tallest man-made monument in the Western Hemisphere, and Missouri's tallest accessible building. Built as a monument to the westward expansion of the United States, it is the centerpiece of the Jefferson National Expansion Memorial and has become an internationally famous symbol of St. Louis.

The arch sits at the site of St. Louis' founding on the west bank of the Mississippi River.

The Gateway Arch was designed by Finnish-American architect Eero Saarinen in 1947; construction began on February 12, 1963, and was completed on October 28, 1965, for $13 million (equivalent to $180 million in 2013). The monument opened to the public on June 10, 1967.

Background

Inception and early funding (1933–1935)

Around late 1933, civic leader Luther Ely Smith, returning to St. Louis from the George Rogers National Historical Park in Vincennes, Indiana, saw the St. Louis riverfront area and envisioned that building a memorial there would both revive the riverfront and stimulate the economy. He communicated his idea to mayor Bernard Dickmann, who on December 15, 1933, raised it in a meeting with city leaders. They sanctioned the proposal, and the nonprofit Jefferson National Expansion Memorial Association (JNEMA—pronounced "Jenny May") was formed. Smith was appointed chairman and Dickmann vice chairman. The association's goal was to create:
