Evaluation of new CHS strength formulae to design strengths
In recent years, extensive numerical analyses were conducted on axially loaded uniplanar K-gap, T-and X-joints made of Circular Hollow Sections (CHS), considering a wide range of geometric param-eters and different types of chord load. Based on the large amount of numerical data, new joint capacity and chord stress equations were derived for CHS joints. This article presents the statistical evaluation procedure to convert the mean strength equations into design equations. Further, as examples, detailed comparisons are shown between the newly proposed (mean) strength equations and available experimental data for T-and X-joints. Similar comparisons are made for K-gap joints but these will be published in the near future. The new design equations are included in the 3rd edition of the IIW Static Design Procedure for Welded Hollow Section Joints (IIW 2008).
