Summary:碩士 === 國立臺灣大學 === 土木工程學研究所 === 104 === Since the establishment of the National Taiwan University, most buildings on campus have been more than 30 years old. In particular, for those buildings with thirteen-ditches tile, the wall tiles have been frequently falling off due to its aging and lack of maintenance. Examining the relevant regulations and policies, there is no legislation to manage and protect the public safety against the wall tile falling. Therefore, the NTU needs a systematic evaluation and diagnosis procedure to prevent it from falling. Through the infrared imaging non-destructive tests, this research aims to develop a diagnosis procedure for public safety and recommendation for building renovation. Furthermore, this procedure was applied to the aged campus buildings with thirteen-ditches tile as a case study. A handbook entitled “Evaluation and diagnosis of building wall tiles through infrared imaging” was established. It was used to assess the deterioration of the wall tiles, the deteriorated area and the public safety impact. The temperature difference between the deteriorated and normal tiles was identified and used to establish the schedule for deterioration check. The test results showed that the infrared imaging technique can clearly identify the location and area where the tiles were not properly glued. This technique can assist the staff to evaluate the tile deterioration and provide an evidence for necessary repair. Finally, it can maintain the integrity of the building wall and meet the requirements of public safety for the buildings.
