Evluation of 1939 erzincan earthquake dynamic behaviour of Erzincan Degirmenlikoy Church over the abscissa damage

In this study, dynamic behaviour of Erzincan Değirmenliköy Church abscissa of which is mentioned to collapse during 1939 Erzincan Earthquake is evaluated. The only formal document related to the church building is defined to be the registration card. Any study related to the structural behaviour of the church is encountered in the literature. Primarily, information about the church is collected and architectural drawings are prepared. Material properties are defined by experimental methods and the support of the literature. Operational modal analysis is done in-situ in order to define modal shapes and modal frequencies of the structure. Considering the results obtained by the operational modal analysis theoretical modal which will be the basis for dynamic analysis is calibrated. When final material properties are obtained, the collapsed abscissa part of the church is added to the model. Dynamic analysis is carried out in on the model with abscissa in order to evaluate the thesis which states the collapse of the abscissa during 1939 Erzincan Earthquake. For the dynamic analysis, 1992 Erzincan Earthquake records are used since there is no numerical record for 1939 Erzincan Earthquake. At the end of the study, it is concluded that; the abscissa did not collapse during the earthquake, damage over the abscissa and the church connection area was occurred, and this damage might progress in time and result in the separation of the abscissa from the structure and end up with total collapse of the abscissa.
