The paper investigates the methods for predicting floor response
induced by an individual walking. A single degree of freedom
(SDOF) model of a structure is developed considering the action of
walking loads. The model is verified by FE modelling of a simply
supported beam and a simply supported plate where the newly
developed walking loads model is used, confirming a SDOF model is
still a useful tool for predicting structural response under walking
loads. The SDOF model is further applied to predict the response of a
multi-panel concrete floor and a composite floor. Comparison
between prediction of the SDOF model and the FE results and the
available dynamic measurements are also given. It is concluded that
the walking routes do not affect the maximum dynamic response
(amplitude and pattern) of floor. The implication of the conclusion is
that the walking load can be applied arbitrarily on a floor, providing it
passes the centre of the floor. The dynamic responses of the FE model
of the full-scale composite floor match in both amplitude and pattern
with the measured dynamic responses. To predict the dynamic
response of a full-scale floor using a SDOF system requires a correct
representation of the floor stiffness.
