Recent proposals to avoid snap-through failure of practical pitched-roof steel frames incorporate the elastic snap-through buckling load of such frames. In this study it Iis shown that the elastic snap-through buckling load used in these proposals is far higher than the snap-through buckling load obtained from a more rigorous elastic analysis.
