The use of steel in building design is increasingly become more popular. Steel design provides a more ductile and robust structure, together with a more practical way of assembly method. All of these are made possible by the advanced construction technology and research. It is foreseen that the use of structural steel will be more favored in the future. Hence, more study needs to be done to ensure a better steel structure quality for future use. As strong and practical a steel structure is, it has a critical point that requires special attention during design: the joints. There have been a number of studies focusing on the joint behavior during column removal, but none of them focused on the joints adjacent to the one above the removed column. Supported with this fact, this final year project will then discuss about the behavior of flush end plate connections located adjacent to the joint immediately above the removed column. This project focused on the creation of a 3 Dimensional, finite element model of the joint. ABAQUS 6.11 was used as the main modeling software. Although the author has been aided with a modern software, it is required that she defines all of the member properties in the model, including the failure criterion of the joint which was found to be the bolts based on previous studies. During the modeling process, combination of 2 and 3 Dimensional models were applied for practicality of the modeling and calculation process. Expertise in such skills will reduce the calculation time significantly. Parametric study is done to further understand the behavior of flush end connection under a sudden column removal scenario. The parameters used in this study are: plate thickness, plate strength, boundary conditions and the number of bays in the model.
