SEISMIC SOURCE-DEPENDENT FRAGILITY CURVES FORA HISTORICAL MASONRY RAILWAY BRIDGE

Bridges are essential structures in the global transportation network. A comprehensive study wascarried out to assess the susceptibility of the Shahbazan masonry arch bridge to earthquakes usingfragility analysis. The objective of this study is to evaluate the seismic safety of the bridge subjected totwo distinct types of seismic sources. In order to this goal, a three-dimensional finite element model ofthe bridge was created, and nonlinear response history analyses were performed utilizing strike-slipand dip-slip strong ground motion records. The results of the investigation indicated that the seismicvulnerability of the Shahbazan historical masonry railway bridge is significantly influenced by thefault rupture mechanism.
