Dynamic modelling of post-tensioned concrete floors using finite element analysis
Until the 1990 s problematic floor vibrations under human-induced dynamic loading, such as
walking, were typically associated with relatively light timber and composite steel-concrete floors.
However, as modern suspended floor structures made entirely of concrete become increasingly
slender, problems associated with occupant-induced vibrations are also becoming a very important
