This paper demonstrates the study of a footbridge's design and also the analysis of the dynamic behavior of the structure due to human-induced load. The bridges are located in Surabaya. Firstly, the human loading as a vibration source of the footbridge is presented together with the model force of the loadings. The next section is the design of the bridge subjected to dynamic load from British Standard, AASTHO and Eurocode. Then the dynamic behavior of the structure is studied using three Tunjungan footbridges as examples. Finally SDOF system is used to calculate the footbridge vibration induced by human load and this is presented and applied to the Tunjungan footbridges, which is very helpful to calculate in practice. The conclusion can be drawn from this study is that the dynamic behavior should be considered in the design of the footbridges due to human-induced loads and using SDOF system is accurate enough to calculate the structural responses of the bridge.
