Title Appendix B Worked Example: Design of a truss node with gusset 12 of 44 5 - 91 For each angle: N 3,a,Ed = 304,7 kN M 3,a,Ed = 13,56 kNm 3.3.2. Connection N3 – Checking of angle Resistance of gross cross-section Longitudinal stress Assuming a uniform distribution of the load in the section, the longitudinal stress is: I v M A N 3,a 3,a,Ed 3,a 3,a,Ed i    Where: A 3,a is the section area of the angle A 3,a = 4302 mm 2 I 3,a is the second moment of area of angle I 3,a = 8,981.10 6 mm 4 v position of considered end fibre (see Figure B.12) v 1 = 87 mm v 2 = 63 mm Then the normal stresses are:  1 = 202,18 N/mm 2 (compression)  2 = -24,29 N/mm 2 (tension)  2  1 e N3 N 3,a,Ed Compression Tension M 3,a,Ed = e N3 N 3,a,Ed υ 2 υ 1 Figure B.12 Stresses in the angle N3
