Energy Dissipation of retrofitted Precast Reinforced Concrete Walls subjected to seismic loading

This paper's purpose is to assess the capacity to dissipate energy of Precast Reinforced Concrete Wall Panels (PRCWP) subjected to seismic cyclic in plane loading. The authors present two specimens with different opening types; one has a door opening cut out from a window opening while the other has a large window opening. The specimens were subjected to in plane reversed cyclic loading, in order to simulate the seismic behaviour. After the specimens were tested, they were retrofitted using Carbon Fibre Reinforced Polymers (CFRP) strips mounted using the Externally Bonded Reinforcement (EBR) technique. The specimens were subjected again to the same loading procedure and the Cumulative Energy Dissipated (CED) for each cycle was computed.
