15. in the world get old in several decades of their service tme Fallmg off of parts of deteriorated structures were often reported and sometmes caused casualties in Japan and many other countries When an earthquake occurs in Darticular deteriorated structures have higher possibility to be damaged or collapsed Thus assessing the health condition of structures is one of the important topics In civil engineering Considering a large number of structures that have been In service more than 40 years in Japan efficient evaluation methods are requested Accordingly this study focuses on the use of infrared thermography camera to detect internal deterioration of concrete structures As a first step of investgation thermography diagnosis hammering test and Schmidt hammer test were carried out to detect internal deterioraton of a concrete retaining wall and the results were compared to evaluate the capabihty of these methods Keywords Thermography Hammering test Schmidt hammer Infrastructures Deterioration 479
