The methodology was applied to 148 reinforced concrete bridges localized at Algiers and represents a part of the strategic bridges. It is a simple and efficient inspection method for the preliminary evaluation of seismic vulnerability of existing bridges. This assessment was conducted based on two earthquake scenarios considering two existing faults that can generate earthquakes with a maximum acceleration of 0.8g. The main findings of this study are summarized in this paper. Keywords: existing reinforced concrete bridges, seismic vulnerability, earthquake scenarios
