Analysis of Nonconservative Elastic Stability of Framed Structures

In this paper an analytical method of nonconservative elastic stability of framed structures is proposed using the linearized finite displacement method and dynamic analysis method, where the effect of damping is disregarded. The critical loads calculated by the proposed method show good agreement with those obtained by the theory of continuum mechanics for the columns. The proposed method can equally be applied to the analysis of nonconservative problems of various kinds of framed structures.
