TORSIONAL BUCKLING OF RESTRAINED THIN-WALLED BARS OF OPEN BISYMMETRIC CROSS-SECTION

The problem of torsional buckling of restrained thin-walled bars of an open constant bisymmetric cross-section was solved using the minimum total stationary elastic energy condition (J. S. Przemieniecki 1968 Theory of Matrix Structural Analysis McGraw-Hill, New York) and the Newton-Raphson method (...

Description
Summary:The problem of torsional buckling of restrained thin-walled bars of an open constant bisymmetric cross-section was solved using the minimum total stationary elastic energy condition (J. S. Przemieniecki 1968 Theory of Matrix Structural Analysis McGraw-Hill, New York) and the Newton-Raphson method (S. C. Chapra and R. P. Canale 1998 Numerical Methods for Engineers McGraw-Hill Book Company). The consideration was restricted to the elastic structures. The example presented in the paper helps to assess the correctness of the proposed solution. This article is an addition to the author’s considerations contained in M. Kujawa 2012 TASK Quart. 16 (1/2) 5.
