What constitutes lateral support to prevent lateral torsional buckling in steel I-Section beams?
For example, is it adequate to provide transverse stringers connected to the compression flanges of parallel beams, i.e. to provide a grid structure? If that is acceptable I presume that you would then only need to check the spans between stringers for buckling?
Alternatively if steel plate was placed on the top of parallel beams and welded to the compression flanges would that be adequate? Would it be permissible to then ignore lateral torsional buckling in the analysis of the beams?
