Dynamic analysis of floors subjected to rhythmic human activities based on the use of biodynamic models: numerical and experimental modelling

Abstract This work aims the assessment of dynamic structural response reinforced concrete floors subjected to rhythmic human activities, based on use biodynamic models, in order consider people-structure interaction effect. Initially, an experimental modal analysis investigated floor , with dimensions 16m x 35m, was performed, identify and assess global behaviour structure. In sequence, a finite element model developed calibrated through results. After that, forced vibration analyses, determined (displacements accelerations). It is concluded that systems modelling induced significant attenuations when compared those calculated traditional “only force” models.
