Abstract
Recent large-scale tests have found that Steel Gravity Framing Systems (SGFSs) with conventional connections were inadequate to support the integrity gravity load combinations under column removal scenarios. To address this issue, detailed connection models in ABAQUS were validated against experimental results and then used to investigate alternative gravity connection details to enhance the integrity of SGFSs. A procedure was developed to design new single plate shear connection details with multiple columns of bolts so that they had design shear capacities equal to or greater than corresponding conventional configurations. Analyses of the connections under column removal showed that improvements in both connection strength and deformation capacity can be achieved using the multi-bolt-column configurations.Proceedings Title
