Dynamic 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 کاملCrowd dynamics on a moving platform: Mathematical modelling and application to lively footbridges
This paper proposes a mathematical model and a computational approach to study the complex multiphysical non linear coupled system that results from the interaction between a moving platform and the pedestrians who walk on it. The described method is based on the mathematical and numerical decomposition of the coupled system into two subsystems and on the two-way interaction between them. In pa...
متن کاملLively voice: a new model for speaking synthetic characters
Speech is one component of most synthetic characters. It is often assumed that the most important objective for such characters is that they should be ‘life-like’, ‘natural’ and ‘believable’. This paper suggests that this is inappropriate and that a better quality is one which we call liveliness. This concept and many of the ideas behind it derive from the theatre. One of the objectives of this...
متن کاملLively quantum walks on cycles
We introduce a family of quantum walks on cycles parametrized by their liveliness, defined as the ability to execute a long-range move. We investigate the behavior of the probability distribution and time-averaged probability distribution. We show that the liveliness parameter has a direct impact on the periodicity of the limiting distribution. We also show that the introduced model provides a ...
متن کاملFluid Viscous Dampers: an Effective Way to Suppress Pedestrian-induced Motions in Footbridges
In the civil engineering field, fluid viscous dampers, used extensively in military applications, have found commercial applications on buildings and bridges subjected to seismic and/or wind storm inputs. Because fluid damping technology was proven thoroughly reliable and robust, implementation on footbridges to suppress undesirable pedestrian-induced vibrations is taking place. . This presenta...
