概要

The present study includes 1) measurements of natural frequencies by ambient vibrations, 2) estimation of the Young's modulus for the used materials based on both dynamic measurements for the minarets and material test of the mortar as well as of the masonry which consists of brick and mortar, 3) estimation of compressive and tensile strength of the mortar, 4) finite element three dimensional elasto-plastic analysis (FEM) in case of dead load for the dome considering the effects of the supporting structure. According to the results of Finite Element analyses, the oval displacement pattern of the base of the dome is in accordance with the actual state of the structure. Comparison of the displacements of two transverse arches, N-Sarch and double arch, seems to give an information that the north to south arch is weaker than the west to east arch.
