ABSTRACT
Transportation has an important and wide impact on the economy, social and cultural structure of countries. Highways and railways are part of the transportation system network where bridges and viaducts are the most critical structures of this system. Therefore, bridge damages not only result in direct losses, but also have social and economic impacts. Seismic behavior of bridges in curved alignment plane contain additional potential damages due to their complex geometries, although similar damages were observed for curved and straight bridges as examined in past earthquakes. In this study, the damages observed in horizontally curved brid- ges in the past earthquakes were investigated and the lessons to be learned according to the results obtained from past earthquakes on the curved bridges were examined.
