Turkey is a country that is vulnerable to earthquakes and has experienced
many major earthquakes that completely destroyed or caused significant
damage to numerous historic structures. Today, using computer software, it
is important to numerically model and analyze historic structures that need
significant restoration and strengthening, to evaluate them from a perspective
of seismic resistance, and to reinforce them without altering their originality.
In this study, a finite element model of the historic Tigris Bridge on the Tigris
River was created. First, the stresses and deformation caused by its own
weight were determined. Subsequently, dynamic analyses were performed in
the time domain using past earthquake ground motion records. Displacement
and stress values obtained for each earthquake record in these time domain
analysis were compared to each other to evaluate the seismic behavior of the
bridge comparatively. The seismic performance of the bridge was determined
on the basis of the “Guidelines on the Management of Earthquake Risks for
Historic Structures” published by the Directorate General of Religious Foundations in Turkey
