Assessment of architectural heritage characteristics and seismic behavior of Ziyaeddin Han Tomb

Historical buildings built by different civilizations that have survived to the present day have an important place within the scope of the protection of cultural heritage. Bitlis province, where many different civilizations lived and located in a strategic position on the Silk Road, contains many different types of historical structures. Within the scope of this study, the Ziyaeddin Han Tomb, which was built in masonry during the Ottoman period, has been taken into account. Besides the architectural features of the tomb, detailed information is given about the current structural situation. As a consequence of on-site measurements, a numerical model of the historical tomb was formed using the finite element method (FEM) and structural analyzes were enforced. Structural analyzes were performed for the tomb, in which the macro modeling technique was applied, considering four different earthquake ground motion levels, 2%, 10%, 50%, and 68%, with a probability of exceedance in 50 years. Besides, the time history analysis was applied to take advantage of the acceleration record of an earthquake that occurred in the near region and the recent history of this tomb located in the city center of Bitlis. The structural performance of the tomb was tried to be determined by using the displacement and drift ratio obtained.
