This paper presents the results of seismic vulnerability analysis of the historic sultaniyya dome constructed for the tomb of Uljaytu. This monumental building is 47 meter high brick masonry structure with a dome type roof. The roof is a two layer shell structure with a base diameter of 25.5 meters. The building was constructed about 700 years ago and is now one of the largest masonry structures in the world. Finite element analysis is used for the structural analysis. Static push-over analysis is performed to assess the seismic resistant of the building for three level of seismic hazard. For an earthquake with return period of 75 years some portions the structure cracks but main portion of the structure remains intact. For an earthquake with return period of 475 years the cracking pattern is similar to the previous case. However due to higher tensile stresses, the crack widths are expected to larger than the previous case. There may be local compression failure in some of main pillar of the structure but the structure is not expected to collapse at this seismic level. For an earthquake with return period of 2500 years the structure is expected to collapse due to compression failure of main pillars.

Sultaniyya and Santa Maria del Fiore ↑
by Marco G. Brambilla
Since Prof. Sanpaolesi advanced the theory that the construction techniques of the Cathedral of Santa Maria del Fiore could be inspired by the structure of the Mausoleum of Uljaitu in Sultaniyya, scholars and architectural historians have argued this hypothesis with fervor and mixed feelings. Iranian scholars have embraced this theory and proudly emphasize it on every occasion. Italians on the other hand have advanced several theories contradicting Sanpaoles’s suggestions.
The article of Prof. Sanpaolesi is presented on this site in its Persian translation. ( here )
Recently a group of international scholars and American brick masons participated in an experiment to rebuild the Duomo in a smaller scale but using the techniques available to Brunelleschi in the 15th century. This experiment was documented and presented by PBS in many public television stations.
See for example:
A similar research regarding the horizonatal arches of IL Duomo was undertaken in 1978 by Thomas E. Settle , published in Annalli dell”Instituto e Museo di Storia della Scienza, Anno III, Fasc. 1, 1978, also included in this site.
Furthermore in March 2012, at an international congress regarding Domes in The World a large number of original research was presented especially regarding the Cathedral of Santa Maria del Fiore. For a full list of articles presented please see: http://www.domesintheworld.com/
