The results are presented for an experimental and analytical study of steel column base plates subject to axial loads and moments. A total of 16 tests were made in which the variables were the anchor bolt size, the base plate thickness, and the ratio of moment to axial load. The results of these tests were used to review the two methods of design presently used, one based on the behavior at working load, and one based on the failure load. Both generally produced reasonable predictions of the capacity for the range of variables in this study. The investigation has demonstrated the need for limits of applicability for the two design methods.
