Title Appendix B Worked Example: Design of a truss node with gusset 30 of 44 5 - 109 With: 2 1 , , 1 1 , , 2 1,a,net 3588mm ;3588) 3912 min( ) ; min(    net a net a A A A we satisfy: 1317 ,52kN 203, 45 1,a,net,Rd 1,a,Ed    N N 3.4.3. Checking of gusset Resistance of cross-section For the determination of the gross cross-section of gusset, we use an approach based on a diffusion of 45° of the internal force N g,Ed (see Figure B.24). 45° 45° 195 Figure B.24 Connection N1 – Diffusion by 45° of the internal force The following criteria must be satisfied: M0 y 1,g 1,g,Ed 1,g 1,g,Ed x,Ed /   f I v M A N    with: 2 g 1,g 2925mm 195    t A 4 3 3,g mm 9268594 /12 195    g t I 195 / 2mm   v We obtain: 2 M0 y x,Ed 355N/mm 139 ,11 190,51 329 , 62        f 3.4.4. Connection N1 – Checking of bolts with regard to the gusset component Determination of the design ultimate shear load F V,Ed for each bolts Due to the orientation of the normal force N 1,Ed , the load on each bolt is not parallel to the edge of gusset. By consequent the components of the design shear load parallel and normal to the end will be performed. EN 1993-1-8 Table 3.4 3)
