Analytical method to detect internal void of seismic rubber bearing was studied. Currently, there is no way to evaluate the presence or absence of internal void of a seismic rubber bearing without cutting it. Therefore, this study aimed to clarify how elastic waves are affected by a void in the seismic rubber bearing using numerical analyses. The validity of this numerical analysis using RCIP method was shown by comparing the experimental results with the analysis results. The results showed that the void affected the amplitude of the observation waves, if the void was near the receiver.
