ABSTRACT: 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.
