Corrugated sheet as a bracing of flat truss chords at their out-plane buckling

Summary/Abstract: Corrugated sheet properly connected with the upper chord of the flat truss can be taken into account in the assessment of the out-plane stability of the upper and bottom chord as well. The term of lateral bracing by the corrugated roof sheeting in purlinless truss chords was discussed. The calculation models for assessment of the lateral supporting of the bottom truss chords a as the flexible restraint in the roof corrugated sheets were given. The procedures of the assessment of resistance due to out-plane buckling of the bottom truss chord braced by roof sheeting were presented.
