A rational Strategy for Seismic Retrofitting of RC Existing Buildings

The paper addresses the topic of seismic behavior of existing RC structures presenting a general strategy for combining member- and structure-level techniques to achieve a cost-effective retrofitting solution. First of all, two key vulnerability parameters are introduced; then the basic equations describing the retrofitting intervention within the mentioned strategy are presented. Finally, two sample applications point out the key features of the retrofitting solution which can be achieved through such a general strategy for two different buildings.
