Abstract :

This paper aims to analyze the sustainability and vulnerability of Davazdah Emam Dome that is located in the historical context of Yazd city against to Earthquake. This dome dated back to Al-Muzaffar era (429 A.H.) and it is the oldest monument with inscription in Yazd. Baked bricks and traditional materials are used to build this dome. In this paper a 3D modeling of dome was made in AutoCAD and carried out its structural analysis in Ansys software. After its structural analysis under own weight and modal analysis and earthquake analysis (Naghan area), we surveys the results and identify the vulnerable and sensitive areas of dome with lowest cost and in a short time. Also the structural characteristics of dome are specified.
