Beams and columns are the back bone of every structure. The principles of detailing and structural behavior are well established for simple structural members such as beams and columns. On the other hand, the detailing, strength and behavior of corner joints, especially those subjected to opening bending moments have not been conclusively investigated. The present work has, therefore, been planned to investigate the behavior of reinforced concrete corner joints with three detailing arrangements subjected to opening bending moment. The objective of this study is to investigate and identify the detailing system promising best structural performance and also to analytically analyze the selected detailing system by using finite element software ANSYS. Concrete is represented by eight nodded element and the reinforcement is represented by two nodded bar element embedded in the concrete elements. Newton-Raphson’s method is employed for the non-linear solution algorithm and a displacement criterion is adopted for checking the convergence of the solution. There is a good agreement between analytical and experimental results.
