An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it.
The many forms of arch are classified into three categories: circular, pointed, and parabolic. Arches can also be configured to produce vaults and arcades.
<h3>Rounded/circular</h3>
Rounded/circular arches were commonly used for ancient arches that were constructed of heavy masonry. Ancient Roman builders relied heavily on the rounded arch to span great lengths.
<h3>The parabolic</h3>
The parabolic arch employs the principle that when weight is uniformly applied to an arch, the internal compression resulting from that weight will follow a parabolic profile. Of all forms of arch, the parabolic arch produces the most thrust at the base yet can span the greatest distances.
Therefore, the parabolic arch is more structurally sound.
