ABSTRACT
ABSTRACT: The paper presents the general planning of a physical/numerical testing of two fullscale existing reinforced concrete buildings. The research investigates the efficiency of different advancedmixed techniques for seismic upgrading/retrofitting ofRC structures.The buildings under study were built at the end of 70s, for resisting only vertical loads and according to out-of-date technical codes. They are destined to be demolished. Thus, they are used as full-scale specimens to be tested up to collapse. The research involves several universities, national institutions and industrial companies. One of the building was divided into six separate sub-structures, in order to examine some seismic upgrading/retrofitting systems: 1. base isolation; 2. concentric buckling-restrained steel braces; 3. carbon fiber reinforced polymers; 4. eccentric steel braces; 5. concentric shape memory alloy braces; 6. steel shear panels. The experimental campaign is going to be finalized on the modified sub-structures of the first building and it is still in progress on the second one.
