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

Abstract

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.

Nonlinear Seismic Assessment of Historical Masonry Karaz Bridge Under Different Ground Motion Records

“…After analyzing 3 historical palaces with the finite element models, Valente ve Milani [18] studied the crack development, earthquake behavior with nonlinear dynamic analysis, and made a general assessment of damage and collapse. Karaton et al examined the earthquake behavior of historical Malabadi bridge, which was built in the 12th century and located in the east of Turkey, for different earthquake levels [25]. As a result of the study, D1, D2 and D3 are from the lowest to the highest ground motion level, no significant damage occurred at the ground motion levels D1 and D2; it was observed that the historic bridge suffered substantial damage at the D3 ground motion level.…”
