The course covers theory and case studies on assessment, repair, and strengthening of existing structures (of RC mainly) subjected to seismic actions. After successful accomplishment, students will be able to specify the bearing capacity of existing structures against earthquakes; also to design possible required interventions for the upgrade of the safety level in accordance to regulations’ provisions
