Sažetak
Seismic vulnerability of a Reinforced Concrete (RC) frame retrofitted with the Carbon Fibre Reinforced Polymer (CFRP) is analysed in this paper. An experimental programme was conducted to determine the way in which concrete strength is affected by CFRP. The improved properties were modelled for different levels of concrete strength using a finite element based software. Using the results obtained during analysis, seismic vulnerability curves were derived for the unstrengthened and strengthened frames. The curves show significant improvement in the performance of unstrengthened RC structure after retrofitting.
