Theoretical Analysis of Human–Structure Interaction on Steel-Concrete Composite Floors
An accurate determination on the acceleration response of a long-span and lightweight steel-concrete composite floor is essential for assessing the floor’s human-induced vibration serviceability, in which the interaction between human and structure should be considered. In the theoretical analysis, the human and floor subsystem are idealized as the linear oscillator model and anisotropic rectangular plate, respectively. This paper presents an analytical approach to determine the acceleration response induced by the walking activity on a steel-concrete composite floor with two opposite edges simply supported and the other two edges clamped. The proposed approach is based on the combined weighted residual and perturbation method. Implementation of this method is simple and avoids cumbersome mathematical calculations. The theoretical solution is validated with experimental results. A sensitivity study using the analytical solution was also conducted to investigate the effects of walking path, damping ratio, and walking frequency on the peak acceleration.
