Stochastic approach in the human-induced vibration serviceability assessment of grandstands

Popis výsledku v původním jazyce

Recent experimental studies on human perception of vibrations in grandstands indicated that the quantity required for assessment of the vibration serviceability limits of the structure is the RMS acceleration and/or displacement value. In stochastic calculus and under certain circumstances, this approach corresponds to the second-order moment properties. To this end, active crowd forces are represented in terms of filtered Gaussian white noise processes with non-stationary mean values and the passive spectators are modeled as single-degree-of-freedom biodynamic systems. In the first case, a passive crowd is neglected and uniform random spatial distribution of an active crowd is adopted. Then, biodynamic models with random masses are added to the structure assuming deterministic spatial distribution, and finally, a random spatial distribution of a passive crowd under the assumption of deterministic distribution of an active crowd is described. In all these cases, the structure is treate
