<p>In this paper, a computational approach is undertaken to determine the rotational stiffness and moment capacity provided by typical “pinned” column base-plate connections in low-rise metal buildings by analyzing a wide-range of connection parameters. The most influencing details of the connections on the overall behavior were identified. First, development and validation of high-fidelity computational models using experimental data are described. Then, the validated models were used to perform a parametric study to understand the effect of configurational details on the rotational stiffness and moment capacity of the column base-plate connections with anchor rods between the flanges. Anchor rod diameter, by itself, and in combination with base-plate thickness, was found to be the most influential parameter on the moment capacity of connections with smaller web depths. For larger web depths, the number of anchor rods was influential in the moment capacity, particularly, in one of the loading directions.</p>
