Abstract

Abstract: The companion paper[1] presents a theory to account for the effects of local and/or distortional buckling in a seven degrees of freedom beam finite element analysis. The theory considers the effect of local and/or distortional buckling as a reduction in tangent rigidities, and determines the reduced tangent rigidities by an a priori post-local or post-distortional buckling analysis of a short length of section. In this paper, the presented method is incorporated into the open source software package OpenSees which was previously modified to account for warping effects[2] . The accuracy of the method is validated by comparison with shell element results for beams, columns and frames.
