Strengthening of RC Beam and Column Joint by Using CFRP & GFRP

This paper will give the information about strengthening of different parameter by using CFRP & GFRP. Strengthening of existing structures has become a major part of construction activity in our country. Many civil structures are no longer safe due to increased load specifications in the design codes. The beam column joint is the crucial zone in a reinforced concrete moment resisting frame. It is subjected to large forces during severe ground shaking and its behaviour has a significant influence on the response of the structure. The assumption of joint being rigid fails to consider the effects of high shear forces developed within the joint. The shear failure is always brittle in nature which is not an acceptable structural performance especially in seismic conditions. The revisions of Indian code provisions have necessitated strengthening of several existing structure in country.
