This paper attempts to give designers an insight into the beam-column problem. The important parameters such as (i) the ultimate strength of columns and beams which are special cases of beam-columns and (ii) secondary effects (P-δ and P-Δ), that should be considered in the ultimate strength design of beam-columns, are identified and discussed. Ultimate strength design interaction equations recommended and proposed in the United States for different categories of beam-columns are then presented. Important features of these equations are summarized. Directions of further research are indicated.
