Determination of Dynamic Characteristics of Historic Beyazıt Tower

The Beyazıt Tower, located within the Beyazıt Campus of İstanbul University, was chosen as a reference structure to assess its dynamic characteristics due to its historical significance. The tower, which is a historic masonry structure, was analyzed using the finite element method with shell and solid 3D models. Ambient vibration tests were conducted to evaluate the accuracy of the analysis results. Based on the findings from the experimental study, the numerical models were updated, and the most suitable material properties were identified. The accuracy of the analysis results among the different models was also discussed. Additionally, a foundation was established for long-term monitoring studies by determining the dynamic characteristics through experimental methods. These studies will help identify any changes that may occur over time, allowing for the monitoring of potential damage and the detection of any impacts from natural disasters or human activities on this unique structure.
