A Dynamic Analysis of the Cable-Stayed Footbridge in Čelákovice Town

Original language description

The submitted paper is dealing with a dynamic analysis of a footbridge, which is situated in Čelákovice town (Czech Republic) and which serves for crossing of the Labe River. The investigated footbridge was designed as cable-stayed continuous bridge with spans 43+156+43 m. The horizontal load-bearing structure of this footbridge was constructed as prefabricated with the segments made of Ultra-High Performance Concrete (UHPC). It is the first footbridge in Czech Republic where the UHPC was used. As was found out, some of the natural frequencies appropriate to the global mode shapes of the footbridge belonged to the range, which is typical for the pacing frequency of walking or running. Therefore, it was decided to perform a dynamic analysis in order to estimate a comfort level of pedestrians. The results of a numerical dynamic analysis will be described and presented in the submitted paper. The numerical analysis was performed through the modal decomposition technique for particular load states such as synchronized runners, vandals and ordinary traffic. The pedestrians were mathematically described by DLF (dynamic loading factor) and GRF (ground reaction forces) movable models with constant velocity of motion. Moreover, the DLF models were used for description of an ordinary traffic, which was considered as stochastic motion of random pedestrians. The particular realizations of an ordinary traffic were provided by Monte Carlo simulations. Each of these realizations generates the properties of each pedestrian, such as pacing frequency, mass, arrival time and side of entrance on the footbridge from individual probability distributions. All of these quantities are considered as independent except the velocity and pacing frequency. The velocity of motion is coupled with the pacing frequency by the simple phenomenological relation.
