Title Appendix B Worked Example: Design of a truss node with gusset 35 of 44 5 - 114 Determination of the design slip resistance F s,Rd With n = 2, the number of the friction surfaces relatively to the gusset, we obtain: p,C M3 s S,Rd F k n F    = 197,68 kN EN 1993-1-8 3.9 EN 1993-1-8 3.9.1 (1) Checking bolts – Individual checking Each bolt has to be verified. Table B.18 and Table B.19 summarize only the checks for the bolt b 1 and b 2 .
