A data processing methodology for infrared thermography images of concrete bridges
Hiasa, Shuhei; Birgül, Recep; Çatbaş, Necati (Pergamon-Elsevier Science Ltd, 2017)This study presents a methodology to improve the usability and efficiency of infrared thermography (IRT) for subsurface damage detection in concrete structures. A practical and more objective approach to obtain a threshold ... -
Effect of Defect Size on Subsurface Defect Detectability and Defect Depth Estimation for Concrete Structures by Infrared Thermography
Hiasa, Shuhei; Birgül, Recep; Catbas, F. Necati (Springer/Plenum Publishers, 2017)This study aims to reveal the effect and correlation of delamination size and defect shape for using infrared thermography (IRT) through FE modeling to enhance the reliability and applicability of IRT for effective structural ... -
Experimental and numerical studies for suitable infrared thermography implementation on concrete bridge decks
Hiasa, Shuhei; Birgül, Recep; Matsumoto, Masato; Çatbaş, F. Necati (Elsevier Sci Ltd, 2018)Capturing the temperature difference between sound and defective parts under ambient conditions is key for infrared thermography (IRT) on concrete bridges. This study explores the favorable time windows for concrete bridge ... -

Hiasa, Shuhei; Birgül, Recep; Çatbaş, F. Necati (Springer Heidelberg, 2016)A detailed investigation of infrared thermography (IRT) for civil structures is presented by considering different technologies, data analysis methods and experimental conditions in the laboratory and also in the field. ... -
Investigation of effective utilization of infrared thermography (IRT) through advanced finite element modeling
Hiasa, Shuhei; Birgül, Recep; Çatbaş, F. Necati (Elsevier Sci Ltd, 2017)Infrared thermography (IRT) has been used experimentally for concrete delamination detection. The past studies were conducted with limited experimental conditions, which make a difference in delamination detection. As a ... -
Practical identification of favorable time windows for infrared thermography for concrete bridge evaluation
Watase, Azusa; Birgul, Recep; Hiasa, Shuhei; Matsumoto, Masato; Mitani, Koji; Catbas, F. Necati (Elsevier Sci Ltd, 2015)Infrared Thermography (IRT) is one of the nondestructive inspection techniques to detect delaminations in concrete bridge decks. These defects are identified by capturing the temperature gradient of concrete surfaces. In ... -
Utilizing Infrared technologies as a non-destructive evaluation for maintenance of concrete structures
Hiasa, Shuhei; Watase, Azusa; Birgül, Recep; Matsumoto, Masato; Mitani, Koji; Catbas, F. Necati (Crc Press-Taylor & Francis Group, 2015)The aging of road infrastructure is becoming a serious problem worldwide. Although the number of aged structures is increasing rapidly, inspection and maintenance for them cannot catch up with the speed due to the limited ...
