Floor Vibration Criterion for Cold-Formed C-Shaped Supported Residential FloorSystems

摘要

Floor vibration due to normal human activity were investigated for cold-formedsteel C-shaped residential floors systems to recommend a suitable desgn 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.
