This paper is a sequel to recent publications in which a novel method to allow for the P-delta effect of steel sway frames designed by ultimate limit state approaches was proposed. In this paper the new P-delta method is examined by way of a wider parametric study covering various sub-assemblages and also a full framework. The method does not require the calculation of the effective column lengths and in principle would remain valid where fully plastic analysis is adopted by design codes. It is concluded that this extremely simple method can lead to savings in materials as well as in design time compared with conventional effective length-based procedures.
