| description | The invention discloses a method for improving the comfort level of an existing pedestrian bridge. Measuring point acceleration in the running process is simply measured by an accelerometer to updatea finite element model, the number, parameters and positions of tuned mass dampers are optimized on the basis, and the comfort level of the existing pedestrian bridge is improved by optimized analysisof the dampers. The method is simple to apply and good in flexibility, modal parameters can be detected in the running state of the measured pedestrian bridge, measurement of input excitation signalsis omitted, and measuring results are high in precision. On the basis, by optimization design of each TMD (tuned mass damper), damping effects are good, and the comfort level of the pedestrian bridgeis effectively improved. By the method, the comfort level of the existing pedestrian bridge can be more effectively improved.
