Symmetry Relations in Crossed-Arch Domes

Abstract

Karbandi, crossed-arch domes or ribbed domes are strategies used to cover large span spaces that depart from a set of arches that are secant to the tracing base circumference, and are rotated several times along the vertical central axis. The number of divisions, rotations, juxtaposi- tion, and the relations with the space layout establish symmetrical relations or define symmetrical modules. In this paper, a comparison between East and West traditions is made, highlighting the similarity of early examples and the increasing complexity, sophistication, and levels of systemati- zation of the Eastern tradition.
