7.4.1 General

(1) Provided that the geometry of the joints is within the range of validity given in Table 7.1, the design resistances of welded joints between circular hollow section members should be determined using 7.4.2 and 7.4.3.

(2) For joints within the range of validity given in Table 7.1, only chord face failure and punching shear need be considered. The design resistance of a connection should be taken as the minimum value for these two criteria.

(3) For joints outside the range of validity given in Table 7.1, all the criteria given in 7.2.2 should be considered. In addition, the secondary moments in the joints caused by their rotational stiffness should be taken into account.
