. In early 2014, strong earthquakes occurred on the Island of Cephalonia and buildings with significant design errors were heavily damaged. The building that is being studied is a two-storey reinforced concrete building, which was affected by the specific earthquakes. The structural model of the building is regular in plan as it consists of parallel frames arranged in dense grid but it is non regular in elevation as there are no infill walls located in the down floor. In the first part of this paper, the seismic assessment of the structure is presented. It is an attempt to verify the damages which occurred to the building during the earthquakes. In the second part of this paper, strategies for structural intervention are suggested. Firstly, it is intended to reduce the seismic demand of the structure through the implementation of base isolation systems. Specifically the appliance of lead rubber bearings (LRB) and friction pendulum systems (FPS) has been studied. Secondly, it is intended to increase the stiffness of the ground floor by placing metal braces. The study is based on results from nonlinear analyses. The analyses that have been used are the pushover analysis and the nonlinear time history analysis.
