Description
Steel moment connections are used where continuity is required between beam and columns. Research on moments connections has primarily focussed on major-axis connections. An in-depth investigation of I.S. EN 1993-1-8 was completed to identify the design rules of connections. Simple connections such as cleats, fin plates and splices were investigated briefly in order to gain a greater understanding of how they behave and transfer load before researching two types of minor axis moment connections; one where the end plate is connected directly to the column web and one where the end plate is bolted to another plate which is welded to the edges of the column flanges. The study herein concentrates on the former type of connection. Structural tests were carried out on end plate connections in the Heavy Structures Laboratory in Cork Institute of Technology. Load-displacement and moment-rotation curves were plotted and deformation and yield failure patterns were identified and documented. Finite element analysis was carried out on LUSAS to verify the results achieved in the structural testing. The moment capacity and initial stiffness of each connection were obtained from equations taken from I.S. EN 1993-1-8. It was observed that these results presented both conservative and non-conservative results and further investigation is recommended.
