![]() ![]() These are allowable stress design (ASD) and load and resistance factor design (LRFD), and both are compared with the focus on material/cost saving as cost is the major issue in underdeveloped and overpopulated countries. Two design approaches are popular in steel footbridges designing. ![]() In this paper, complete designing process of steel footbridges is conducted using STAAD Pro: a dedicated steel structure design and analysis software, under unpredictive loading, i.e., dead, live, pedestrian, wind and seismic loading. With the advent of powerful software, the designing process has become more accurate and less time-consuming. In the last century, they were mostly designed using manual calculations. Steel footbridges are common means of connecting two zones separated by any kind of physical obstruction to the pedestrian crossing. ![]()
