Title:           Analytical study on reinforced concrete beam column joint wrapped with CFRP
Authors:    Nagumalli Kedar Nath, T. M. Jeyashree
Abstract:   Buildings are collapsed due to brittle failure of reinforced concrete (RC) beam column joint, which faces severe damages by earthquakes of high magnitude. The focus of this study is to evaluate the behavior of beam column joint retrofitted with carbon fiber reinforced polymer wrapping (CFRP). Five beam column joint specimens including one conventional specimen and four retrofitted specimens of different configurations of CFRP sheets were modeled using ANSYS and was analyzed to find the improvement in various parameters of beam column joint. Parametric study is carried out by varying thickness of CFRP wrapping and the thickness considered are 2 mm and 6 mm for both single layer and double layer. From the analysis output, it is observed that CFRP reduces the deflection and improves stiffness, maximum principal stress and minimum principal stress.
