This paper discusses the changes brought about dynamic characteristics of floor structure and human sensitivity to vibration by differences in the damping performance of floor structure. For this study, the vibration tests of floor structures fitted with tuned mass damper were performed. From the test results, the tuned mass damper improves the damping effect of floor structure, and suppresses the overlapping and amplification of floor vibration caused by walking. Floor structures with smaller natural frequency receive greater controlling effects and the analytical results correspond well to the test results. Vibration level (JIS C 1510) and maximum converted acceleration are useful guides for evaluating human sensitivity to vibration.
