In the present study, it is aimed at how Fatih Sultan Mehmet suspension bridge behaves under site-specific multi-point earthquake excitations, in accordance with, determining the structural earthquake performance of the bridge. For this aim, based upon recently-proposed 3-D finite element model of the bridge is updated and response parameters of the bridge are determined, and site-specific strong ground motions in x, y and z directions are produced for each support of the bridge considering the Mw=7.5 scenario earthquakes on the main Marmara Fault. Non-linear earthquake time-history analysis of the bridge subjected to multi-point excitation is then carried out using these seismic ground motion time-histories. By means of this analysis, the effect of site-specific multi-point earthquake excitations on the bridge is investigated and earthquake response characteristics of the bridge are compared to those obtained from uniform support excitations
