Historic arch bridges, a common feature of Turkish infrastructure, represent a significant aspect of the country’s cultural heritage. To ensure their continued existence and preservation, it is essential to conduct a detailed examination of their structural features and behaviours. This study aimed to investigate the performance of the historic Yeşiltepe Bridge under earthquake conditions. To achieve this, the bridge was modelled using the SAP2000 finite element software, enabling a deeper understanding of its structure and the prediction of its behaviour during an earthquake. In order to ascertain the dynamic behaviour of the historical bridge, modal analysis and nonlinear time history analysis were conducted. The results of the modal analysis yielded period values, mass participation rates and mode shapes for the bridge. The time history analysis yielded displacement, base shear force and stress values for the historical structure, which were subsequently presented in graphical form. The data obtained from the study enabled the identification of the critical regions of the structure exhibiting the highest stress concentration values.

Highlights

  • The study employs advanced analytical tools like SAP2000 for finite element analysis, enabling precise modeling of the historic Yeşiltepe Bridge's structural behavior under seismic conditions.
  • The study identifies the upper parts of the arch and edge supports as particularly susceptible to damage, thereby providing vital information for targeted reinforcement.
  • The study proposes the implementation of targeted reinforcement techniques, such as the utilization of carbon fibre-reinforced polymer strips and steel plates, with the objective of enhancing the tensile strength and durability of the bridge.
