Catenary ring

A catenary ring is a type of structural element that takes the form of a curve known as a catenary, which is the shape that a hanging flexible chain or rope assumes under its own weight when supported at its ends. In architectural and engineering contexts, catenary rings are used to create stable and efficient structures, often in the design of arches, bridges, and roof systems. The mathematical equation for a catenary curve is typically expressed in terms of hyperbolic functions.
