Analogies between the hanging chains and standing structures: an arch and the dome of Saint Peter's Basilica in Rome (Giovanni Poleni, 1748). In architecture, the funicular curve (also funicular polygon, funicular shape, from the Latin: fūniculus, "of rope" [1]) is an approach used to design the compression-only structural forms (like masonry arches) using an equivalence between the rope with ...
For example, the wedge-shaped voussoirs of a brick arch can be made by cutting the regular bricks ("axed brick" arch) or manufactured in the wedge shape ("gauged brick" arch); [28] structurally, by the number of hinges (movable joints) between solid components. For example, voussoirs in a stone arch should not move, so these arches usually have ...
The rise (height) of a round arch is limited to 1 ⁄ 2 of its span, [7] so it looks more "grounded" than a parabolic arch [3] or a pointed arch. [7] Whenever a higher semicircular arch was required (for example, for a narrow arch to match the height of a nearby broad one), either stilting or horseshoe shape were used, thus creating a stilted arch and horseshoe arch respectively.

A mudbrick catenary arch A catenary curve (left) and a catenary arch, also a catenary curve (right). One points up, and one points down, but the curves are the same. A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times.
A parabolic arch is an arch in the shape of a parabola. [1] In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.
Multifoil arch in the Aljafería, Zaragoza, Spain.
