A numerical study on the static strength of CHS (circular hollow section) joints with the multiplanar double-K configuration is presented. The aim of the work was to establish a valid and accurate finite element model for an extensive parametric study and to investigate the various factors which influence static strength. These factors included modelling the effect of the weld geometry, boundary conditions at chord and brace ends, mode of loading, chord length and material properties. The numerical results were rigorously calibrated against existing experimental data. The study has given an insight into the many aspects of elastic-plastic finite element analysis which is gradually replacing experimental testing as the main tool of research in tubular joint technology.
