This paper extends the validity of limit load solutions for thin-walled branch junctions, previously proposed by the authors, to thick-walled cases. It is achieved simply by re-normalizing the thin-wall expressions by the limit loads of thick-wall tubes instead of those of thin-wall tubes. Comparison with finite element results shows overall good agreement.
