The unexpected failure of welded connections observed during the 1994 Northbridge earthquake and the 1995 Kobe earthquake lead to the initiation of research for finding an alternative connection for use in seismic resisting steel moment frames. The Extended End plate connection is considered as a suitable and efficient alternative to welding in seismic regions. The study of end-plates in moment resisting connections for beam to beam splices and beam to column connections dates to the early 1960’s. These connections were primarily used in pre-engineered metal buildings. This study deals with the design and analysis of Extended End Plate Connections. In this current study, 3 configurations of Extended End plate connections are designed using AISC design parameters, for American Steel Sections and Indian Steel Sections. These connections are then modelled and analyzed by Finite Element Analysis using the ANSYS Workbench software. 6 models are prepared in total and analyzed. Using the ANSYS Workbench Software parameters such as Total Deformation, Maximum Principal Stress, Maximum Principal Strain and Hysteresis Curves are evaluated. The results obtained from the Design and Finite Element Analysis is then compared between the American Steel sections and the Indian Steel Sections to understand whether the Indian Steel Sections conform to the American Codal Provisions.
