ABSTRACTOne of the special features of Iran’s architecture is the transformation of the square base to a circle at the base of the dome which is referred to as gusheh sazi(corner construction). Karbandiis one of its variants, which also plays a role in load transfer. The aim of this paper is to study karbandiin order to recognise and review its decorative and structural functions. This is a descriptive-analytical study based on field and library information. By reviewing different samples, the authors argue that karbandihas been used not only as a decorative element but also as a load-bearing element in transforming the square base to a circle. However, this name has been used sometimes to introduce mere decorative elements which are hung from the ceiling, such as muqarnas, kasehsaziand qatarbandi. As a whole, three main categories of karbandimay be considered: (1) structural karbandiwhich is related to the main ceiling; (2) karbandiwhich is related to brickwork in lower crusts of double-shell domes and the lower cover of sloping roofs and (3) something between masonry work and finishing work in the construction which is often used in half domes in entrances, portal arches (iwan) and apses.
