Condition assessment of different historic bridges using Non Destructive Techniques (NDT) with FTIR analysis in Izmir after the Samos Island earthquake

The study aimed to contribute to condition assessments of historic bridges in Izmir, Turkey and the estimation of their predictable functional lifetime after the Samos earthquake. This document is a summary of the study into the reliability of Non-Destructive Techniques (NDT) for testing the state of different historic bridges impacted by the October 30, 2020 Earthquake. Besides providing data on material characteristics, NDT can help identify hidden bridge structure defects, such as cavities and moisture. This study also used FTIR (Fourier Transform Infrared Spectroscopy) spectral data analysis in conjunction with NDT as a multidisciplinary evaluation technique and demonstrates the value of this approach in the field. This study is of special relevance to bridge engineers.
