Abstract
<p>The study proposes a simple index for evaluating the deterioration of reinforced concrete columns by statistically examining three impact acoustic properties; sound pressure level of the maximum amplitude, the cluster analysis for the normalized 1/3 octave band levels, and the energy decay time of 2.5 dB. The proposed index is developed based on the field measurement survey at Nikkyu jutaku and validated using the results of another building (Building 39) on Hashima Island. The results show that the proposed index generally provides a reasonable evaluation.</p>
