Abstract

The geometric nonlinearities in elastic sway frames are examined. Various approximate methods of second‐order analysis for sway frames are reviewed and the conditions limiting the use of these procedures are stated. A rational method for combining the nonsway and sway moments is developed. A practical method of including the effects of sway deflections due to gravity load moments and out‐of‐plumb construction in the approximate second‐order analysis is derived.
