NONLINEAR STABILITY ANALYSIS OF STEEL MEMBERS BY FINITE ELEMENT METHOD

This paper presents a verstatile curved-shell finite element method and corresponding analytical models for solving the elastoplastic local, overall, and local-overall interactive instability problems of steel members. Some special techniques are deduced to treat the deflection compatibility of plate intersections, boundary conditions, and initial imperfections of steel members, which are the most serious obstacles for the analysis of plate and shell structures by finite element methods. Some numerical examples are given, and it is noted that compared with the results of other numerical methods and experiments, the accuracy of the present theory has proved quite satisfactory.
