Human Comfort Investigation of Steel‐Concrete Composite Floors Subjected to Rhythmic Dynamic Actions

In the last decades, several excessive vibrations problems in buildings floors have been observed, due to human activities. Therefore, this research work investigates the dynamic structural behaviour of a steel‐concrete composite floor with total area of 315 m², when subjected to rhythmic human actions, based on the use of different mathematical formulations in order to define the dynamic loadings. The floor numerical modelling was implemented in the finite element program ANSYS, aiming the dynamic structural response analysis. The results indicate important levels for peak accelerations values, resulting in excessive vibrations and discomfort to the building users.
