ABSTRACTThis paper describes the analytical and experimental investigation of a 50m span pedestrian suspension footbridge in Cenlral Wales, UK. In the analyrical study modelling of the three dimensional slructure determined vibration modes involving deck, towers and cables. The prorotype resting €mployed hammer (impact) testing and excitation by pedest.ians to determine the corresponding measured modes. The testing showed that adequate descriptions of vibration chamcteristic of flexible structures can be obta…
