 The Origins of Barrel-Roof Forms 

     Quonset Huts share a common background with Roman high style, vernacular curved-roofs, and rectangular plan structures[1]. The arch is the most basic and essential structural component of the Quonset Hut. The arch allows the hut to be elongated for long distances and maximizes the volume underneath the arches using a barrel vault system, a masonry canopy of semi cylindrical cross sections supported by parallel walls[2]. Another way that these barrel roofs were formed was using complex system of purlins and rafters to form a semi cylindrical shape—the bow-string truss[3].
