Abstract:

Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of two and four people. A linear regression model is used to statistically characterize the footstep load-time history. Group loads are randomly simulated by using the experimental parameters affecting individual footsteps an coherency among the people in a group.
