Study on non-linear analysis of arch bridges subjected to ground motion

Thanks to the cantilever launching technique, arch bridge building has once again become popular throughout world. Today, these structures are one of three main types long-span bridges, along with suspension and cable-stayed bridges. Arch have a complex behavior during powerful earthquakes because rib is an element that primarily susceptible large axial compression force brought on by dead loads. The nonlinear dynamic analysis using STAAD Pro V8i software earthquake loading subject this research. Due their easy load bearing qualities, bridges short medium spans currently being constructed frequently for traffic bypass. Therefore, it necessary assess its stability in event earthquake. STAAD-modeled bridge's nonlinear, time history analysis. research study uses pro. For Time History analysis, data from Bhuj Earthquake 2001 used, Rudramata Bridge, which collapsed Earthquake, researched. primary focus displacement, time-velocity, time- acceleration responses lateral And results demonstrate displacement less than Bridge all directions.
