Parametric study of Unstiffened multi-planar tubular KK-Joints
Multi-planar tubular joints became widely used in steel structures especially in industrial and offshore project. However, the current design procedures are still not accurate enough and depend on studying each plan separately and adjust the joint capacity using some correction factor. The aim of th...

| description | Multi-planar tubular joints became widely used in steel structures especially in industrial and offshore project. However, the current design procedures are still not accurate enough and depend on studying each plan separately and adjust the joint capacity using some correction factor. The aim of this research is to present a mathematical formula to calculate the capacity of symmetrical loaded multi-planar KK joint. A verified ANSYS model was used to generate 172 records for parametric study with different geometry, member sections and material properties. The outputs of the parametric study were analyzed using (GRG) solving technique to develop the final predictive model. The novelty of the developed model is it can predict the actual joint capacity as 3D joint not as approximated 2D joint as previous literatures. The developed model consists of two equations based on failure mode. One for local chord failure where the chord thickness is less than 25 times its diameter and the other for global chord failure if that ratio is more than 25. The results of the developed formula were compared with experimental test results and showed average accuracy of 92.5%. |
