Pushover analysis of historical Elti Hatun Mosque

Abstract

Historical structures, being an important part of cultural heritage, have shown extreme vulnerability to seismic actions. A clear understanding of the performance of them is thus of critical importance for taking preventive actions. This paper presents a case study related to pushover analysis of a historical masonry structure located in Tunceli, Turkey. The evaluated monument is Elti Hatun Mosque located in the seismic zone 2 according to seismic zone map of Turkey. The mosque is modeled and analyzed with Diana finite element software on the base of real dimensions measured on site. Material properties are obtained from literature on the base of similar studies. The results are presented as pushover curves, crack distribution and failure modes. The results show that the safety level of the structure is acceptable at its current condition.
