A flat arch is a type of arch that has a more or less horizontal intrados and extrados. It is constructed of mutually supporting voussoirs that radiate from a center below the arch. Flat arches are often used in bridges and other structures where a low-profile arch is required. They are also sometimes used in buildings, such as in the construction of vaults. Flat arches are typically less strong than other types of arches, such as the semicircular arch. However, they are also less expensive to construct and require less material. As a result, flat arches are often used in applications where strength is not a primary concern.
Flat Arches have typical spans between 4’-12’ (1.22-3.66 m) and arch rises of 0” (0 cm). Arches are commonly paired with wall depths of 8”-16” (20.3-40.6 cm) and a course depth between of 4”-16” (10.2-40.6 cm).
