The effectiveness of a particle-tuned mass damper was investigated experimentally using a small single story steel structure. Two cases were examined. First, the damper was suspended from the structure with a fixed weight inside the container and in the second case the fixed weight was replaced by particles of equal mass filling two unequal size compartments. In both cases, the frequency of the damper was close to the natural frequency of the structure. The dynamic behavior of the structure with the damper was examined under random excitation. It was found that while the root mean square (RMS) of the response acceleration was reduced in both cases, the substitution of the fixed weight with the particles increased the attenuation of the motion. Reduction of the RMS of the relative displacement was observed after the first few seconds of the excitation. The excitation level has a minimal effect on the effectiveness of the particle-tuned mass damper with the two unequal size compartments.
