Seismic upgrade of RC buildings using CFRP sheets

Abstract

The seismic upgrade of existing reinforced-concrete frame buildings usually calls for evacuation of occupants, and the time available for construction works is often quite limited. These problems usually cause time delays and additional costs on seismic rehabilitation projects. One of the ways of improving seismic resistance of structures is to use CFRP (carbon fibre-reinforced polymer) sheets and steel fuse elements. The cost-effectiveness and practical value of this technical solution is proven in the paper through appropriate analyses.
