From the reference:
Full Truss Design Example – Rectangular Members. For Joint A the loads in the branches differ by more than 20%; therefore, this is not a pure K connection. Branch members transmit part of their load to the other branch (K connection) and part through the chord to be resisted by the point load (cross connection). The strength of the connection is determined by linear interaction of the proportion of the branch load involved in each type of load transfer.
Refer to the figure in the reference for additional details.
