7.5.3 Multiplanar joints

(1) In each relevant plane of a multiplanar joint, the design criteria given in 7.5.2 should be satisfied using the reduced design resistances obtained from 7.5.3(2).

(2) The design resistances for each relevant plane of a multiplanar joint should be determined by applying the appropriate reduction factor p given in Table 7.19 to the resistance of the corresponding uniplanar joint calculated according to 7.5.2 with the appropriate chord load in the multiplanar situation.

Members 1 and 2 can be either in compression or tension. N2Ed/N1Ed is negative if one member is in tension and one in compression.
