Dynamic Action Induced By Walking Pedestrian
نویسندگان
چکیده
The main focus of this paper is on the human induced forces. Almost all existing force models for this type of load (defined either in the time or frequency domain) are developed from the assumption of perfect periodicity of the force and are based on force measurements conducted on rigid (i.e. high frequency) surfaces. To verify the different authors conclusions the vertical pressure measurements invoked during the walking was performed, using pressure gauges in various configurations. The obtained forces are analyzed using Fourier transformation. This load is often decisive in the design of footbridges. Design criteria and load models proposed by widely used standards and other researchers were introduced and a comparison was made. Keywords—Pedestrian action, Experimental analysis, Fourier series, serviceability, cycle loading.

Human Walking Vertical Force and Vertical Vibration of Pedestrian Bridge Induced by Its Higher Components
The purpose of this study is to identify human walking vertical force by using FFT power spectrum density from the experimental acceleration data of the human body. An experiment on human walking is carried out on a stationary floor especially paying attention to higher components of dynamic vertical walking force. Based on measured acceleration data of the human lumbar part, not only in-phase ...

متن کاملInvestigation of Pedestrian Walking Loads on a Cable Stayed Footbridge Using Modal Testing and Fe Model Updating
This paper describes the finite element modelling, dynamic testing and finite element model updating of a newly constructed, 35m span, cable-stayed footbridge. A numerical simulation, using an updated FE model, was conducted to evaluate the accelerations that would be induced by a walking pedestrian. The results from the simulation were compared to corresponding experimental measurements, and w...
متن کاملDynamic Analysis of Suspension Footbridges Using an Actual Pedestrian Load Model Compared with EUR23984 EN Requirements
The suspension footbridges are very flexible due to their geometrical structure; hence they may face severe vibration problems induced mainly by natural forces and pedestrians crossing. By exceeding a certain limit, these vibrations can disturb the serviceability of the bridge as well as health and safety of the structure and pedestrians. Therefore, standard design guidelines are sets of recomm...
متن کاملA dynamic network loading model for anisotropic and congested pedestrian flows
A macroscopic loading model for multi-directional, time-varying and congested pedestrian flows is proposed in this paper. Walkable space is represented by a network of streams that are each associated with an area in which they interact. To describe this interaction, a stream-based pedestrian fundamental diagram is used that relates density and walking speed in multi-directional flow. The propo...
