Abstract
Hagia Sophia, Istanbul, was constructed in 537. The building shows particular characteristics. Huge dome was supported by the arches, the tympanum and the piers. To stabilize them, the semi domes, the buttress and the pendentives were arranged. These are also supported by other complex structures. Hagia Sophia has been survived under several earthquake attacks. In this paper, the structural behavior of Hagia Sophia was analyzed by use of vibration record of the structure. The vibration record was measured by the micro tremor meters. The vibration characteristics of the total building were analyzed by combining the vibration records. Then, the deformation characteristics and the dynamic behavior of the second cornice were investigated. Applying the finite element method to solve the structure of the second cornice, the structural behaviors were clarified and the cause of the particular deformation was investigated.
