Analysis on Efficiency of Frame Joint Retrofitted with Hybridized CFRP for Strong Column and Weak Beam

Abstract:

The calculation for flexural capacity of beam end and column end were carried out, with the strength effect of slab bar being included. The results for traditional joint specified in design code and that for the joint retrofitted with hybridized CFRP were compared. The results presented the efficiency of flexural strength improvement in beam. It is also shown that for the joint retrofitted with hybridized CFRP, the stress in the reinforce bar for column will increase significantly, while the plastic pivot of column appears later, which tend to exhibit a failure type closer to the beam-pivot or ductile mode.
