Determination of earthquake performance of Kı̇razlıyalı Çenesuyu Bridge without and with seismic isolation depending on soil type

The earthquake performance of bridges is crucial for ensuring the safety and resilience of transportation infrastructure during seismic events. The use of seismic isolation in bridges allows for effective absorption of seismic energy during earthquakes. Thus, it minimizes the effects of ground motion on the bridge and reduces the potential risk of damage. This innovative approach not only preserves the structural integrity of bridges but also contributes to the overall seismic resilience of the transportation network, thereby minimizing economic losses resulting from earthquakes. This thesis aims to determine the earthquake performance of the Kirazlıyalı Çenesuyu Bridge. Within this scope, nonlinear analyses in the time history were conducted using the SAP2000 software on both seismic isolated and non-isolated models of the bridge for two different soil types, utilizing real earthquake records. As a result of the analyses, the base shear forces of the bridge, horizontal and vertical displacements in the piles, dynamic characteristics of the bridge, and shear force and bending moment values in the columns were obtained.
