Title Appendix B Worked Example: Design of a truss node with gusset 19 of 44 5 - 98 Horizontal loading The horizontal loading coming from the results of Table 3 is shown on the Figure B.16. On this figure we indicate for each bolt how we are processing for the determination of its coefficients b  and 1 k . So, we can specify for each bolt: the end and edge distances ( e 1 and e 2 ) and the spacing ( p 1 , p 2 and L ) to consider the type; end or inner, or end and inner b 3 b 2 b 1 b 4 b 5 b 6  b  b  b k 1 k 1 k 1 k 1 Figure B.16 Connection N3 – Gusset component – Horizontal loading The general expression for the design bearing resistance is: M2 1 b u b,Rd   f d t k F  EN 1993-1-8 Table 3.4 According to Table 3.4 of the Eurocode 1993-1-8, the coefficients  b and k 1 are determined from: For end bolts        ;1, 0 ; 3 min u ub 0 1 b,end f f d e           min 1, 4 1, 7; 2,8 1, 7; 2,5 0 2 0 2 1,end d e d p k For inner bolts         ;1, 0 ; 4 1 3 min u ub 0 1 b,inner f f d p          min 1, 4 1, 7; 2,5 0 2 1,inner d p k Table B.6 gives the value of the horizontal component of the design bearing resistances F b,bi,h,Rd .
