Title Appendix B Worked Example: Design of a truss node with gusset 14 of 44 5 - 93 Here, the holes are in the tension zone (see Figure B.12). Accounting for 3,a 3,a,eff A A  , the following criterion should be fulfilled: M0 3,a y 3,a,c,Rd 3,a,Ed  A f N N   With 2 3,a 4302 mm  A : 1527 , 2kN 304, 7 3,a,c,Rd 3,a,Ed    N N Buckling resistance A compression member should be verified against buckling. This condition has been verified in the section dealt with the verification of the members (see § 4 of this document). 3.3.3. Connection N3 – Checking of gusset plate Resistance of cross-section For the determination of the gross cross-section of gusset plate, a diffusion of 45° of the axial force N g,Ed is assumed (see Figure B.13). 286,5 45° 45° 112 Figure B.13 Connection N3 – Diffusion by 45° of the axial force The following criteria must be satisfied: M0 y 3,g 3,g,Ed 3,g 3,g,Ed x,Ed /   f I v M A N    with: 2 g 3,g 4297 ,5mm 286,5    t A 4 3 3,g mm 29395706 286,5 /12    g t I 325 / 2mm   v Then: 2 M0 y x,Ed 355N/mm 291, 72 141,80 149,92        f
