Basket-handle arch

Quality 0.00 · 0 views · Updated 22 days ago

A basket-handle arch (also depressed arch or chop arch) is characterized by an intrados profile formed by a sequence of circular arcs, each tangent to its neighbors, resulting in a smooth transition between arcs. The shape of a basket-handle arch resembles but is different than that of a semi-ellipse, with the latter featuring a continuous curvature that varies from the extremities of the long axis to the apex of the short axis.
