- As the population is increasing day by day, need of the pedestrian bridges are also increasing simultaneously. In the last few decades, due to the new technology and improvement in materials, the cross-sections of bridges are decreasing day by day. As a result of this mass and stiffness significantly decreases which leads to smaller natural frequencies, resulting in more vibration due to dynamic loads. For the analysis of pedestrian bridge dynamic excitation also plays a major role. Here, Pratt Truss and Tied Arch bridge of spans 30m, 40m, 50m, 60m are considered. Total 8 models are made and Finite element analysis is done on SAP2000 software. Time History and Modal analysis are used for the analysis purpose. Various responses like time period, frequency, peak acceleration and displacement are compared and conclusion is drawn depending upon the obtained results.
