Abstrait:

Load models of the ground refraction forces (GRFs) has a great practical importance in dynamic analyses of the structures used by pedestrians, including footbridges. One of the important type of dynamic loading of a susceptible and light-weight structures can be the GRFs generated during rhythmically repeated squats. In the paper the characteristic and mathematical models of the GRFs generated during squats have been presented. The proposed models were elaborated on the basis of laboratory tests of GRFs carried out by author using the force platform and were initially validated during numerical analyses and filed tests of exemplary footbridges. The results of the field tests and numerical analyses have confirmed correctness and effectiveness of the models used to estimate the values of the GRFs and to calculate the dynamic response of the structure.
