| Abstract: | This paper proposes a new computational approach in order to study the complex multi-physical non-linear coupled system resulting from the interaction between a structure and the pedestrians walking on it. The described method is based on the mathematical and numerical decomposition of the coupled system into two subsystems and on the twoway interaction among them. In particular, the dynamics of the crowd is modelled by referring to a macroscopic description in analogy to the one of a compressible flow. The proposed approach is applied to the lateral vibrations of footbridges under human-induced excitation. First, the computational parameters of the model are optimised. Hence, the effects of the crowd initial density and runnability conditions are evaluated on motionless deck. Finally, some results from simulations of the crowd-structure interaction are proposed. |
