Interaction Analysis of Asymmetric Sway Subassemblages
Publication: Journal of Structural Engineering
Volume 110, Issue 10
Abstract
A simple alternative elastic‐plastic method to account for the P‐Delta effects of asymmetric sway structures is proposed. The method is applied to story subassemblages and represents an extension of a similar procedure previously applied to plane frames. The failure load of a given story is determined on the basis of an interaction principle which incorporates the rigid‐plastic collapse load and the elastic buckling load of the story. In contrast to existing equivalent methods no iterations are required. A numerical example is provided to demonstrate the use of the technique.
