Numerical analysis of steel beam–column connection under cyclic loading with dog bone type fuses
This work follows the latest development trend in resilient structures by arresting inelastic damage in a small replaceable link at a predetermined location. Toward this, here innovative beam fuse has been proposed with dog bone shape of parabolic, circular, smooth surface, triangle, and sharp type. These fuses are also provided with a flange of 8 mm thickness and web plate of 4 mm thickness. Comparative analysis has been carried out for five beam–column sub-assemblages in ABAQUS FEM software. In this modeling, the bolted end plate has been omitted as the focus is only on the connection’s pure fuse behavior. SAC loading protocol has been adopted to evaluate the cyclic behavior of the connections. Strength degradation, ductility, and energy dissipation have been studied. All the fuse connections show excellent ductility under the cyclic loading. For all the fuses based on rupture index, cracking may occur between the web plate and the flange plate of the fuse. Here fuse with smooth dog bone shape shows the highest amount of energy dissipation.
