Abstract: “A growing number of structural problems associated with excessive vibrations of steel-concrete composite floors due to human rhythmic activities is the main motivation for the development of an analysis methodology supported by design guides and several researches to obtain the dynamic response of a steel-concrete composite floor spanning 40 by 40 m when subjected to human rhythmic dynamic loads. Therefore, this research develops a study based on the use of two different mathematical formulations used for modelling human rhythmic actions (aerobics). Furthermore, it was observed that high levels of annoying vibrations were reached during the aerobic activity.”

Keywords: steel-concrete composite floors, dynamic loading models, human comfort, excessive vibrations, human comfort.
