<p>Numerous failures occur in steel moment-resistant frame buildings when the steel beam column connection is subjected to earthquake loading. This study includes experimental verification of the connection as well as an investigation of a new steel dog bone fusion connections. This connection's testing and simulation results have been compared to those of another unique fuse connections. After experiencing earthquake damage, this fuse connection can be changed, saving money on building maintenance and restoration. The experimental findings demonstrate a strong agreement with the simulated data. The PEEQ index of connection has been examined. The displacement out of plane behavior has been analyzed. A component-based fuse assembly model has been created, and its initial stiffness values have been compared to experimental and numerical results. The end-plated connection has a higher energy dissipation characteristic, but there is a risk of bolt failure and stress concentration at the beam column face. Based on the extensive analysis, it is possible to conclude that the parabolic fuse assembly is required to provide substantial energy dissipation without causing any damage to the connection's beam column face.</p>
