Title APPENDIX A Worked Example: Design of a continuous chord connection using splice plate connections 6 of 24 5 - 59 4. Global checking of the cross-section chord 4.1. Effect of the shear force EN 1993-1-1 6.2.10 Determination of pl,Rd Ed V V With: w v A A h t w   = 3959 mm 2   M0 v y pl,Rd 3  A f V  = 811,3 kN EN 1993-1-1 6.2.6(2) From where pl,Rd Ed V V = 0,002< 0,5 So, no reduction due to the shear force needs to be taken into account. EN 1993-1-1 6.2.10 (2) 4.2. Combination M + N – Effect of the axial force EN 1993-1-1 6.2.9.1 817 , 4kN 1567 , 4 M0 w w y Ed     h t f N Allowance has to be made for the effect of the axial force. EN 1993-1-1 6.2.9.1 (5) 4.3. Combination M + N – Consideration of fastener holes Axial force Under tension axial force, the fastener holes should be considered. Category C connection  the design tension resistance is: M0 net y net,Rd t,Rd  A f N N   EN 1993-1-1 6.2.3(4) For the net cross-section, we consider 7 holes for fastener (2 by flange and 3 for the web). The net area is: net A = 4707 mm 2 Therefore: net,Rd N = 1671 kN Bending moment With f f A b t  and 0,f f f f,net 2 A A d t   For each flange in tension, one checks: 653, 2kN 473 0,9 M0 f y M2 u f,net      A f f A So, the holes for fasteners in the flange should be considered.
