Abstract: This paper describes a methodology for nonlinear dynamic response analysis of framed structures using the mode superposition method. A portal frame example is presented and compared to classical methods for determination of critical buckling loads. Results indicate that the critical buckling load via a dynamic analysis is one-half that of a static analysis due to a dynamic magnification factor of two for long duration dynamic loads of constant magnitude.
