Dynamic design of footbridges
Webfor extending the design process to dynamic loads. In order to take the dynamic behaviour into account at the stage of the design study, it is necessary to model pedestrian loading on the footbridge, which result from rhythmical body motions of persons. Vibrations of footbridges lead mainly to serviceability issues WebFootbridges are amongst the structures that most strongly impact their users. This is consequence of their smaller scale when compared to roadway and railway bridges, as …

WebFeb 18, 2024 · Nakamura’s model is widely used to describe lateral vibrations of a footbridge induced by crowd. The predicted responses of Nakamura’s model were compared with measured data of T-bridge and M-bridge in Japan to demonstrate the validity. However, the predicted responses based on Nakamura’s model almost … WebDec 29, 2024 · Footbridge design has evolved rapidly in recent decades, leading designers to use new and lighter materials ( Firth and Cooper 2002) and structural arrangements …
WebSep 1, 2013 · In this paper, the vertical vibration response of footbridges subjected to dynamic loads induced by walking humans is assessed via a response spectrum approach. The dynamic walking load in the vertical direction is applied on the bridges using two different loading schemes: (1) a stationary load at the mid-span and (2) a moving load … WebDec 16, 2024 · The minimum and maximum crowd load to be applied on bridges irrespective of the span length is therefore 2.5 kN/m 2 and 5 kN/m 2 respectively. To check the effect of span length on the value of the crowd load, equation (1) can be used. For instance, the crowd load on a pedestrian bridge of length 30 m is given by;
