Performance of beam column connections is not satisfactory during the earthquake excitation. In order to understand the complex mechanisms and satisfactory behavior of beam column connections, lots of investigations have been done. The most critical zone in reinforced concrete moment resisting frames would be the beam column connection. The behavior of beam column connection once it is subjected to large forces during earthquakes has a great impact on the response of the structure. The shear failure has a brittle nature which is not a desirable structural performance during earthquakes. New type of shear reinforcements are introduced in this study for the purpose of reaching a higher performance and material capacity for the connection. The first specimen is made according to conventional method of design. The second specimen introduces a continued shear resistance system against discontinued conventional shear resistance system. The third model consists of spiral reinforcement and longitudinal GFRP (Glass Fiber Reinforced Polymer) bars. By investigating the model with GFRP bars and to improve the properties of GFRP reinforced beam column joint, hybridization of GFRP to be done. Two types of hybridization namely GFRP crust with steel core and steel crust with GFRP core were done. The specimen having hybridized bars checked for higher ductility and lower deformation. In this case corner beam column joint were modelled and analysed using ANSYS finite element software.
