Investigation of material deterioration and seismic behavior of Fertek and Hançerli Churches in Cappadocia Region

Abstract

Cappadocia is among the rare natural and cultural centers on earth with its fairy chimneys, underground cities, rock churches, stone structures and natural beauties. Among these structures, Fertek and Hançerli Churches that are subjected to the scope of the study are very original artifacts with their superior construction techniques and rich workmanship according to the period they were built. In this study, the architectural features of Fertek and Hançerli Churches which were built in the 19th century and located within Niğde province in the Cappadocia Region were defined and material deteriorations were determined. In the light of these determinations, the existing static properties of these structures were examined using the Dynamic Finite Element Analysis program. Discoloration, vegetation, crack formation, moisture problems and partial mortar and stone losses were detected in both church structures. When the analysis results are evaluated, it has been determined that the structures need repair and improvement, depending on the region and soil class, considering the earthquake forces.
