Floor vibration due to normal human activity were investigated for cold-formed steel C-shaped residential floors systems to recommend a suitable design criterion Dynamic impact and static loading tests were performed on twelve full size laboratory floors and five two-joist line laboratory floors to determine the influencing characteristics of vibrations in light-gauge steel framed floors. Similar tests were conducted on eleven floors located in existing houses. Limited subjective evaluation, in terms of annoying vibration levels, of all floors was recorded.nFour existing floor vibration criteria were investigated:1) Australian Standard Domestic Metal Framing Code, 2) Swedish Building Technology Design Guide developed by Professor Sven Ohlsson, 3) United States Proposed Timber Floor Vibration Criterion developed by Johnson, and 4) Canadian Timber Floor Criterion developed by Donald Onysko.
