A segmental arch is a type of arch with a circular arc of less than 180 degrees. It is sometimes also called a scheme arch. The segmental arch is one of the strongest arches because it is able to resist thrust. To prevent failure, a segmental arch must have a rise that is equal to at least one-eighth the width of the span. Segmental arches are often used in bridges and other structures where strength and stability are important.
Segmental Arches have typical spans between 4’-12’ (1.22-3.66 m) and arch rises of 7.1”-21.3” (18-54 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).
