the chord while case 14 and 16 are in-plane bending moments and case 15 and 17 are out of plane bending moments on both ends of chord. Boundary conditions for each load case on braces are selected such that, no influence due to secondary bending moments in the chord is present in the SCFs and SNCFs of each line. Fig. 11 demonstrates all the loading cases of this parameter study.
