P‐Delta Effect in Elastic Analysis of Sway Frames
Publication: Journal of Structural Engineering
Volume 113, Issue 3
Abstract
A novel method to allow for the P‐Delta effect of steel sway frames analyzed by elastic methods is presented. The method is a variation of an interaction procedure recently developed for plastically analyzed and designed frameworks. Second‐order design forces are established from empirical graphs and are then used in conjunction with the well‐established ultimate strength interaction equations for beam‐columns. In contrast to existing methods the second‐order forces are determined on a rational basis for the framework as a whole. A numerical example is provided to demonstrate the use of the technique.
