[10] This kind of arch has pinned connections at its base. While these cultures had the arch, they rarely used it except for underground tunnels and drainage systems, where the force of the earth around it provided natural buttressing, or reinforcement. Generally, the concrete blocks are used without reinforcement. These stones are joined together using cement mortar. The arch consists of a curved structural shape that transmits loads over the opening, transmitting them over the shape of the arch to jambs, abutments, or piers on either side. [28], An early European example of a voussoir arch appears in the 4th century BC Greek Rhodes Footbridge.[29]. The center of the stilted arches on a straight line. Without the arch, these constructions would probably not have been possible. Ashlar stones are typically used in constructing flat arches.
