Summary

In 1981 Taiwan entered a period of intense construction, meaning that today many buildings are more than thirty years old. Lack of maintenance has led to frequent safety incidents involving external walls. The study, reported in this paper, focuses on a deterioration diagnostic model for external wall tiles of aged buildings, using both stage one and stage two diagnostic methods. The visual test results are categorized based on their impact on public safety, and renovation strategies are proposed. Stage 1 diagnosis mainly adopted the degree, extent and relevancy (DER) visual inspection deterioration assessment method. For enhanced accuracy, this research adopted the infrared thermal imaging detection method to double confirm the visual inspection results. After producing an external wall tile condition indicator (CI). For stage 1 diagnostic results that fall in a grey area, stage 2 diagnosis was carried out using a tap tone test, followed by fast Fourier transform and pattern recognition to analyse the tapping results. Finally, this study provides a deterioration evaluation criteria for external wall tiles replacement recommendations and a standard operating procedure for deterioration diagnosis. This study also recommends directions for future amendment of regulations, and provides a basis of reference for the government in determining urban renewal, renovation and maintenance strategies.
