Part 5: Detailed Design of Trusses 5 - 17 ULS Load combination n°1 (Gravity loading) – Axial force (N) in kN ULS Load combination n°1 (Gravity loading) – Bending moment (M) in kNm ULS Load combination n°2 (Uplift loading) – Axial force (N) in kN ULS Load combination n°2 (Uplift loading) – Bending moment (M) in kNm Figure 3.2 Worked example – Axial forces and bending moments It is interesting to note the form of the moment diagrams in the member:  In the chords and the diagonals, the self weight generates a bending moment with a parabolic shape  In the chords, continuous modelling (members rigidly connected at both ends) leads to moments at the nodes.
