Seven types of floor systems, with panels of various sizes and supporting beams with different joist spacings, were constructed based on actual conditions. For the vibration measurement, an ISO rubber ball dropped from a height of 20\u2009cm was used as an impact source to reproduce human walking. The vibration characteristics were evaluated by calculating the vibration acceleration values and the autocorrelation function parameters for the floor structures. Finally, a human walking experiment was conducted to investigate subjective responses to the vibration characteristics of floating floors. From the results, it was found that the vibration acceleration values and walking discomfort varied with the supporting conditions of the floors and that these were highly correlated with each other. It was also found that more than 75% of subjects accepted the floors when the vibration value of the floor in terms of vibration does value (VDV) is below 4.8\u2009ms\u22121.75. In addition, a practical regression of the VDV was obtained and design guidelines for floating floors were suggested.<\/jats:p>","DOI":"10.1121\/1.4894686","type":"journal-article","created":{"date-parts":[[2014,10,8]],"date-time":"2014-10-08T00:31:21Z","timestamp":1412728281000},"page":"1702-1711","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Effects of vibration characteristics on the walking discomfort of floating floors on concrete slabs"],"prefix":"10.1121","volume":"136","author":[{"given":"Jae Ho","family":"Kim","sequence":"first","affiliation":[{"name":"Hanyang University Department of Architectural Engineering, , Seoul 133-791, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin Yong","family":"Jeon","sequence":"additional","affiliation":[{"name":"Hanyang University Department of Architectural Engineering, , Seoul 133-791, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023073108070378100_c1","first-page":"313","article-title":"Evaluation of floor impact sound insulation in reinforced concrete buildings","volume":"90","year":"2004","journal-title":"Acta Acust.
