Abstract
This paper presents a mathematical model to generate synthetic narrow band vertical force signals due to individuals walking. The model is fitted to a unique database comprising many directly measured vertical walking force time histories due to diverse population of human test subjects walking on an instrumented treadmill at a range of speeds, yielding a random approach to generating their artificial - yet realistic counterparts. Integrated in computer software, the modelling strategy presented offers a radical departure from traditional hand-based calculations of human-induced vibrations towards more realistic and more reliable assessment of dynamic performance of pedestrian structures that could be adopted in modern design practice.
