Abstract—The performance of beam-column joints have long been recognized as a significant factor that affects the overall behavior of Reinforced Concrete (RC) framed structures subjected to large lateral loads. The reversal of forces in beam-column joints during earthquakes may cause distress and often failure, when not designed and detailed properly. In the present study, finite element modeling of four type of exterior beam-column joint specimens is done by using ANSYS11.0. The first specimen conforms to the guide lines of IS 13920: 1993 for seismic resistant design. Second one is detailed with additional diagonal cross bracing bars at joints and beam reinforcements. Third with cross bars in beam region of 6 mm instead of cross bars in joint. Fourth specimen with cross bars of 8 mm instead of 6 mm in beam region.The specimens are subjected to similar reverse cyclic loading to simulate earthquake loading in structures. The experimental resultsfound out by Bindhu and Jaya (2010) is compared with the studies carried out by these finite element models. The comparison shows better performance of the joint when it is provided with cross bars of 8 mm in beam region.
