Experimental investigation of exterior reinforced concrete beam - column joints strengthened with hybrid FRP laminates

Sumathi Marimuthu, Greeshma Sivasankara Pillai

Abstract

In the present study, an experimental and theoretical investigation is carried out on the reinforced concrete exterior beam-column joints strengthened with the hybrid fibre reinforced polymer (HFRP). The effect of reversible distress that develops in the joint region due to seismic force is determined experimentally by applying reverse cyclic loading on the tip of the beam. In theoretical analysis, the shear strength of strengthened joints was determined, and satisfactory correlations with experimental results were established. Hence, the proposed physical model provides valuable insight into the strength behaviour of the joints.
