Vibration serviceability assessment of floors has been traditionally based on a scenario of a single person walking along a path
which will generate maximum vibration level. This is due to the difficulty of predicting the real positions and paths of the
walking people. With such a design scenario, it is possible to obtain calculated responses, which could be both over- or underestimated, depending on the specifics. This could be due to considering only one person walking along one walking path in the
simulations. This aspect in the design guidelines could be improved if realistic modelling of people’s movements is utilised.
Hence, this paper examines the performance of the social force model to simulate the behaviour of people’s movements on
floors. This method has been widely used to model a crowd of people in evacuation and panic situations. However, it has been
reported in the literature that this approach could be used to model people’s movements in normal situations as well. The
simulation carried out in this paper focuses on the interaction between walking people themselves and between walking people
and the surrounding boundaries in typical office floors. The results show that reasonable and realistic behaviour of the floor
occupants could be obtained using the social force model. Furthermore, utilising the ‘heatmap’ can help the designers to
visualise and obtain information about the proportion of time spent by walking individuals at various points on the floor. This
approach can be adopted in a more realistic procedure for the vibration serviceability assessment of floors
