KLASİK DÖNEM (15. YY - 17. YY) OSMANLI ANIT MİMARİSİNDE KULLANILAN STRÜKTÜREL DEMİR ELEMANLARIN TAHRİBATSIZ MUAYENE YÖNTEMLERİ İLE TESPİTİ, SULTAN AHMET CAMİİ ÜZERİNDEN BİR KESİT

Abstract

The expansion of the Ottoman Empire brought about a period in which it reached its peak in culture, architecture and the arts.Particularly in the 16th century, advancements in iron technology played a crucial role in architectural development.The use of iron for structural purposes in architecture allowed structures to reach monumental dimensions.Structural iron elements are used to withstand the internal stresses and tensile forces caused by earthquakes in a structure.According to experimental research, it has been determined that masonry structures reinforced with iron are more effective in resisting tensile forces compared to those without iron reinforcement (Demir, 2012).Calderini and Lagomarsino's study in 2015 emphasized the advantages provided by structural iron elements against earthquake loads.However, damages arising from the internal structure of iron elements or external factors may occur.This situation can lead to weaknesses in the static structure of buildings.Therefore, the durability of iron elements providing advantages against seismic loads and the determination of their positions are critically important in determining interventions in the structure.In assessing the condition of structural iron elements, non-destructive testing methods that allow the detection of discontinuities without causing harm to cultural heritage play a significant role.Techniques such as groundpenetrating radar, magnetic induction, ultrasonic tomography, thermography and videoscopes are commonly used in the evaluation of historic structures.However, to obtain accurate and reliable results, it is often necessary to use multiple methods simultaneously.Within the scope of the study, the detectability of structural iron elements in historical artifacts using non-destructive testing methods was investigated.In this context, measurements conducted with radar, magnetic induction, and videoscope devices during the restoration process of the pier of Sultan Ahmet Mosque were analyzed, supported by laboratory experiments.
