The scope of this study is to present the results of an experimental investigation of the
behavior of shear deficient exterior beam–column joints retrofitted by carbon-fibre-reinforced
polymers (CFRP's). The joints have no transverse reinforcement so they called non-seismic
(NS) joints. Four NS-grade of beam–column joints were tested under reversed cyclic loading
and compared with one Seismic joint (S-grade specimen). The experimental program was
divided into 3 separated phases including the damaging phase, the repairing phase and the …

The scope of this study is to present results of an experimental investigation on the
behaviour of critical external beam–column joints repaired or/and strengthened with a
combination of epoxy resin injections and carbon‐fibre‐reinforced plastics (C‐FRP) sheets
and to extract useful and practical conclusions. The experimental program comprises 12
external beam–column joint connection subassemblages tested in cyclic loading. From the
observed responses of the examined specimens it can be deduced that the technique of …
