AbstractKarbandies’ masonry ribs construction technology is influenced by form and size, on one hand, and traditional architects’ creativity, on the other hand. Some of the exclusive characteristics of construction techniques of Kar-bandies’ ribs are revealed, after investigating and identifying of some of traditional construction ways of them, investigating contemporary studies conducted in the field and comparing the methods. The masonry ribs have been built in different forms over time and such different forms result in formation of different construction technologies. The masonry ribs’ form and size and the bricks’ arrangement way have direct effect on their construction process. The aim of the present paper is to determine construction technology of the masonry ribs used in different Karbandies. Hence, in line with achieving this goal, it also tries to investigate geometric arrangement of bricks in masonry ribs. The present study, for the first time, presents a comparative structure to study different implementation ways of Kar-bandies’ masonry ribs and reasons for similarities and differences among different samples. Moreover, the present study tries to draw implementation way of different types of ribs with the aid of 2D and 3D software and by doing library studies, field understandings and interviewing the related masters and then the collected data were studied, comparatively. Data-gathering of this research included library studies which included written, listening and visual methods of books, articles and dissertations. Interviewing traditional masters, who are expertise in the field, were used in the samples analysis. Then according to the master builders’ advice, structural form of karbandi ribs was modelled using three-dimensional software type. In this study karbandie’s masonry ribs were divided into three categories of radial brick vault, pitched brick vault and a combination of them based on their brick arrangement way. Investigation of the results indicated that the bricks due to their geometrical form and variety in shape can result in various combinations. Different factors including materials, centering, dimensions, bay size and other factors are influential in bricks arrangement of the ribs. ter builders’ advice, structural form of karbandi ribs was modelled using three-dimensional software type.
