Strengthen Earthquake Damaged and Seismically Deficient Structures with CFRP

Earthquake damaged and seismically deficient structures require reinforcement to restore structural integrity and resist movement. Carbon fiber reinforced polymer can be used to strengthen architectural components and can improve the overall seismic performance of a structure. The main advantages of carbon fiber reinforced polymer in seismic reinforcement can be summarized as follows:

a) Efficiently prevents sudden failure of concrete under seismic loading and can also be used to increase the inelastic rotational capacity of reinforced concrete members

b) Increases the global displacement and energy dissipation capacity of the structure, thus improving the overall behavior of reinforced concrete members when subjected to seismic actions

c) Has little effect on the stiffness or mass of the structure so a re-evaluation of the seismic demand after strengthening is typically not required
