Finite element modeling of steel bar buckling in FRP-confined RC columns [PDF]

, 2015
Fiber-reinforced polymer (FRP) confining jackets offer an attractive solution for the seismic retrofit of reinforced concrete (RC) columns. For an accurate prediction of the strength and ductility of FRP-confined RC columns, it is necessary to understand
