The following article presents the results of analysis of slender bridge structure to dynamic loads induced by movement of people. Further is emphasized the importance of modal analysis of structures thus the calculation of eigenfrequencies and modes of vibrations such as prediction of behaviour under dynamic load. In considering of large ratio between the weight of structure and pedestrians will not be discussed the type of loading causing adverse response of the structure in terms of first and second limit state. In this case the decisive criteria are on the part of pedestrians. Detailed examination and comparison with the criteria of comfort specified in the standards is not carried out in this paper. Attention is focused on the design of the computational model and method of application load representing the movement of people. Computational model of footbridge is designed to allow for variable load application in space and time. The same procedure can simulate the movement of small group of pedestrians that move in sync walking. The program system ANSYS was used for the analysis
Klíčová slova
