Like a beam, truss is also susceptible to Lateral Torsional Buckling. ... As far as a truss and the tension bottom chord being stiff enough to act as a brace for the vertical members, thats another story. ... Oiler buckling is conributed to compression memebers, where tension members do not behave similarly.[PDF]Tension Slenderness Ratio - ICC-ES

When designing the compression chords of a timber truss in a braced roof, South African National Standards. (SANS) 10163:1 (2003) recommends a minimum effective length for out-of- plane buckling of no less than 15 x b, which is 540 mm for a 36 mm-wide member. This effective or out-of-plane buckling length of the top ...Timber Construction Manual

Stress variation at buckling load. Figure 2.1 Flexural buckling. In steel bridges, flexural buckling is usually only of concern for trusses (where chords and diagonals are in compression) and for bracing members that are subject to compression. In composite bridges, flexural buckling is normally only of concern for bracing.Tubular Structures XV: Proceedings of the 15th International ...
