Summary
The main objective of this paper is to investigate the dynamic behaviour of building steel-concrete composite floors when subjected to human rhythmic activities. The investigated structural model was based on a steel-concrete composite floor spanning 10m by 10m, with a total area of 100m2. This system represents a typical interior floor bay of a commercial building for gym purposes, and designed according to the usual ULS and SLS Eurocode provisions. The peak accelerations found in the present numerical analysis indicated that the investigated floor presented problems related to human comfort. Hence, it was detected that this type of structure can reach high vibration levels that can compromise user comfort. In addition, the use of a tuned mass damper system (TMD) was simulated in order to improve the human comfort.
