Title Appendix B Worked Example: Design of a truss node with gusset 40 of 44 5 - 119 3.4.6. Connection N1 – Design of net cross-section Gusset component For a connection in tension, the design of the net cross-sections have to be verified. Verify on the net cross-section marked 1 on the Figure B.32. For this section, we have to satisfy: M0 net1 y b 1,g,Ed b  f A n N n t  EN 1993-1-8 3.4.1 (1) c) and Table 3.2 Where 2 b  n number of bolts relative to the cross-section 4 bt  n total number of the connection With  1 net A 2194 mm 2 We satisfy: 778kN 203, 4 M0 net1 y b 1,g,Ed b     f A n N n t Angle component We have been already verified the net cross-section (see 3.4.2).
