A probabilistic walking load model that accounts for inter- and intra-subject variabilities has been developed
to generate synthetic vertical load waveforms induced by pedestrians. The mathematical model is based on
a comprehensive database of continuously recorded pedestrian walking forces on an instrumented treadmill,
having a wide range of walking frequencies. The proposed model is able to replicate temporal and spectral
features of real walking forces, which is a significant advantage over conventional Fourier series models. The
load model results in more realistic force time histories than previous models, since it incorporates significant
components of the spectra that are omitted in Fourier series approaches. The proposed mathematical model
can be implemented in vibration serviceability assessment of civil engineering structures, such as building
floors and footbridges, to estimate more realistically dynamic structural responses due to people walking
