A mathematical and computational model used to simulate Crowd-Structure Interaction in lively footbridges is presented in this work. The model is based on the mathematical and numerical decomposition of the coupled multiphysical nonlinear system into two interacting subsystems. The model is conceived to simulate the synchronous lateral excitation phenomenon caused by pedestrians walking on footbridges. First, the model is applied to simulate a crowd event on an actual footbridge, the T-bridge in Japan. Then, two sensitivity analysis are performed on the same benchmark to evaluate some properties of the model. The model shows a good agreement with data in literature and could be a useful tool for designers and engineers in the different phases of footbridges design.

Abstract
A mathematical and computational model used to simulate Crowd-Structure Interaction in lively footbridges is presented in this work. The model is based on the mathematical and numerical decomposition of the coupled multiphysical nonlinear system into two interacting subsystems. The model is conceived to simulate the synchronous lateral excitation phenomenon caused by pedestrians walking on footbridges. First, the model is applied to simulate a crowd event on an actual footbridge, the T-bridge in Japan. Then, two sensitivity analysis are performed on the same benchmark to evaluate some properties of the model. The model shows a good agreement with data in literature and could be a useful tool for designers and engineers in the different phases of footbridges design.Pubblicazioni consigliate
