ABSTRACT
The 2nd edition of CIDECT design guide No. 1 (Wardenier et al., 2008a) has assumed that the value of η is close to zero for transverse branch plates.Therefore, further simplifications can be implemented to the partial design strength function as follows;
On the other hand, AISC steel design guide No. 24 (Packer et al., 2010) adopted one common equation for the strength function of both T-and X-types of joints, as follows;
Exploring the development history of the axial capacity of the transverse branch plate-to-CHS joints refers to one common approach that does not differentiate between the loading directions of the branch plate; whether tension or compression.
