As the authors showed previously, these tubes are characterised by duplicate bifurcation modes (local or distortional) and, for some geometries, local and distortional buckling may occur simultaneously (local-distortional interaction). A particularly efficient Generalised Beam Theory (GBT) non-linear formulation, specialised for RCPS tubes and employed earlier to characterise their bifurcation behaviour, is used to help pinpoint the occurrence of possible coupling phenomena. The post-buckling results presented and discussed concern columns with different ratios between the critical local and distortional buckling loads, and containing critical-mode initial geometrical imperfections. They are obtained through Abaqus shell finite element analyses and make it possible to draw a few conclusions on the post-buckling behaviour of RCPS columns affected by local-distortional interaction.CRC Press/BalkemaDEC - Departamento de Engenharia CivilRUNGonçalves, R.Camotim, D.Martins, André D.2019-04-16T22:07:36Z2018-01-012018-01-01T00:00:00Zconference objectinfo:eu-repo/semantics/publishedVersion9application/pdfhttps://doi.org/10.1201/9781351210843-70eng9780815381341PURE: 11595811http://www.scopus.com/inward/record.url?scp=85060847967&partnerID=8YFLogxKhttps://doi.org/10.1201/9781351210843-70info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:38:49Zoai:run.unl.pt:10362/66805Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:38:49Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
