Lexicon Catenary Arch _____________________________________________________ A catenary arch is the arch described by the line passing through all the points of centre of gravity of its components. It is the inverse of the figure described by a free-slung chain from which it derives its name, from the Latin word cat?na which means 'chain. It is not a parabolic arch. Catenary arches are strong because they redirect the vertical force of gravity into compression forces pressing along the arch's curve. In a uniformly loaded catenary arch, the line of thrust runs through its center. Catenary arches characterize the work of the Catelonian architect, Antonin Gaudi (See also Reinforced concrete parabolic and catenary arches).
