Preservation of historical structures that have survived from the past to the present and their sustainability; It is possible with education, knowledge and ongoing care. Historical buildings have been damaged over time due to natural and artificial reasons. However, thanks to the craftsmanship of the period in which they were built, they have managed to reach the present day. It is very important to examine the current conditions of these structures, to determine the damage, to choose the most appropriate technique for repair and strengthening, and to make the necessary intervention in a timely manner. In this study, the Historical İplikçi Mosque in Konya was modeled with the finite element model in the SAP 2000 program. On the model, earthquake resistant design rules and calculation methods were compared according to the Regulation on Buildings to be Constructed in Earthquake Zones (06/03/2007) and Turkey Building Earthquake Regulation (18/03/2018). As a result of the study, it was seen that the calculation methods used with TBDY 2018 and the rules to be followed have changed and new building types were added. As a result of the analyzes obtained from the examined structure, it was seen that the structure did not meet the DBYBHY 2007 principles, but the TBDY 2018 principles.
