A new design equation for side wall buckling of RHS truss X-joints

摘要

The paper presents a new design methodology for equal width RHS X-joints failing by side wallrnbuckling. In the new approach a slenderness parameter is defined based on the elastic local buckling stress ofrnthe side wall, obtained from a Rayleigh-Ritz approximation. When verified against a limited number of tests,rnthe proposed design equation yields excellent results.
