NIST Technical Note 1749 Robustness of Steel Gravity Frame Systems with Single-Plate Shear Connections

This report presents a computational assessment of the performance of steel gravity framing systems with single-plate shear (“shear tab”) connections and composite floor slabs under column loss scenarios. The computational assessment uses a reduced modeling approach, while comparisons with detailed model results and available experimental data are presented to establish confidence in the reduced models. The reduced modeling approach enables large multi-bay systems to be analyzed much more efficiently than the detailed modeling approaches used in previous studies.
