Seismic rehabilitation of beam–column joint using GFRP sheets

Techniques for upgrading reinforced concrete beam–column joints are proposed. The test specimens represent a typical joint that was built in accordance to pre-1970s’ codes. The objective of the rehabilitation is to upgrade the shear strength of these joints and reduce the potential for bond-slip of the bottom bars of the beam. Glass fibre-reinforced polymer (GFRP) sheets are wrapped around the joint to prevent the joint shear failure. GFRP …
