The paper presents a parametric analysis of the Istanbul's ring road viaduct that is currently under construction within the Northern Marmara Highway project. The structure, due to its location on seismic prone areas is exposed to seismic loads of different strengths and different return periods. The study is focused on concrete bridge supports that are design to work in nonlinear range. The parametric study, conducted in MATLAB and SOFISTIK environment, aim at detailed verification of the viaduct's supports performance due to three levels of seismic loads intensity. The research and analysis procedures will be used in recommendations' for development of slender bridge supports of variable geometry with stiffness chosen to achieve the best performance to weak and very strong earthquake.
