Abstract: The behaviour of joints or connections is very complex due to the various factors which influence them, such as geometric imperfection, lack of fit, residual stresses, connection flexibility, geometric complexity, slipping, and non-linear load deformation characteristics. In bolted joints, a variety of components such as angles cleats, end plates, stiffeners, and bolts are used to transfer and disperse loads from one member to the other. Due to use of bolts continuous load paths are employed to transfer the loads. Connections are often the critical component in a structure, and if they fail, progressive collapse is imminent. Therefore, a test program was aimed at investigating the behavior of a bolted beam-column connection such as unstiffened seated connection, stiffened seated connection, and moment resisting. Non-linear analysis was also performed using ANSYS software to compare the results. The study revealed that stiffened seated connection has got higher load carrying capacity and resilience. The analytical approach by ANSYS method can be adopted using modification factors.
