Method for improving comfort level of existing pedestrian bridge

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. 本发明公开了种提高既有人行桥舒适度的方法，通过加速度计测量运行过程中的测点加速度来更新有限元模型，在此基础上优化质量调谐阻尼器的数量、参数以及位置，通过阻尼器的优化分析，提高既有人行桥的舒适度。本发明的
