  7. Abstract:
  8. Monumental structures are cultural and aesthetic bases in every nation, and our duty to maintaining these valuable remnants is obvious clearly. Meanwhile, the vaults have essential role as main elements in the Islamic architecture, and evaluation of their performance as well as retrofitting with regard to placing in earthquake-prone regions has high importance. Therefore, in this dissertation, performance of spherical and pointed domes are evaluated. Hence, 13 traditional Iranian domes are modeled with linear and non-linear material behavior in ABAQUS finite element software to verifying effect of their geometries in seismic performance. Base on Complex behavior of these models, they required time history analysis. Endurance Time method is an intensifying dynamic loadtime historyanalysis which its outstanding nature simplified these procedure as well as submitting acceptable results in the different level of earthquake hazard. In addition, optimal rotational curves with best seismic performance in different earthquake are submitted by establishing link between ABAQUS and MATLAB Genetic Algorithm. At the end, the performance of a real historical domical structure (Emam Reza Shrine) is evaluated
