The Reference Stress/Skeletal Point concept is defined for a beam cross-section and the definition used to reconcile a number of approaches by other workers. Whilst the Limit Load Reference Stress for a constant moment beam is essentially powerful the paper goes on to bring out its limitations for structures (e.g. a uniform cantilever) where a range of Reference Stresses may be more appropriate than a single stress and for structures which are stressed internally. The solutions evolved may assist future development of Best Estimate solutions using Reference Stress/Skeletal Point techniques.
