Design bearing resistance F b,Rd for each bolt Table 3.4 of EN 1993-1-8 gives the expressions of the design bearing resistance. In these expressions, the coefficients b  and 1 k depend on the orientation of the loading, the position compared with the ends of the component and also the position of the other bolts. EN 1993-1-8 Table 3.4 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 Web component Figure A.7 shows how it is processed for the determination of the coefficients b  and 1 k .
