| Abstract: | This paper aimed to analyze the dynamic response of a footbridge under pedestrian dynamic loads.First, dynamic structural model and pedestrian loads model were introduced .Then through dynamic anal-ysis and calculation , the maximal dynamic response was obtained .Results show that in the vertical and lateral vibration directions , the maximal perceived accelerations both exceed the limits .Therefore , the device of TMD was proposed in order to reduce the vibration . |
| Keywords: | dynamic model dynamic analysis maximal acceleration damping solution |
