    Human-Induced Loads on Grandstands as Non-Stationary Gaussian Processes

  • Original language description

    In this contribution, we employ non-stationary filtered Gaussian processes as an enrichment of a periodic mean value in order to approximate crowd loads on grandstands. Our work generalizes previous considerations, where the superposition of a mean value and a stationary filtered Gaussian noise was used, and helps therefore to better predict the response of a structure mainly in the transition stages. We specify general theory of stochastic differential equations within the context of grandstands by recalling particular moment equations, and demonstrate its benefits or drawbacks on two simple examples. Overall performance is measured in terms of the second moment evolutions in time and in terms of the total up-crossings of the system's response. Comparison with previously developed stationary approximation and direct Monte Carlo simulation is provided. Throughout, only an active part of a crowd is considered.
