Structural analysis of human-induced induced vibrations in pedestrian bridges due to the passage of pedestrians is presented. An antecedent of this phenomenon is the Millennium Bridge located in the city of London, which had to close to the public, shortly after its inauguration due to unexpected lateral vibrations produced by the passage of people across the bridge. The present research analyses this effect on a pedestrian bridge in Lima, for transverse, lateral, longitudinal and torsion movements, due to the passage of pedestrians walking with a period similar to the modal periods of the structure corresponding to each direction of movement, finding displacement and acceleration responses. A software Puente.exe was developed to find the response of the peruvian footbridge due the synchronic excitation. |
