Steel Buildings in Europe

Part 5: Joint Design 5 - 91 where: k s = 1.0 for fasteners in standard clearance holes (Table 3.6 of EN1993-1-8) [1] n fs is the number of friction surfaces μ is the slip factor (Table 18 of EN1090-2 [12] ) F p,C = ub s 0, 7 f A [EN 1993-1-8 §3.6.1(2)] A s is the tensile stress area of the bolt  M3 is the partial factor for slip resistance at ultimate limit state 5.3 Check for horizontal shear For a bearing type splice, any horizontal shear V Ed is assumed to be resisted by friction across the splice interface [4] . Basic requirement: V Ed ≤ shear resistance of splice interface The coefficient of friction μ f for a steel interface depends upon the surface condition of the steel and on any coatings provided. Conservatively, for steel with no surface treatment, with mill scale, the coefficient of friction, μ f may be taken as 0,2. Shear resistance of splice interface = Vertical load  Coefficient of friction 5.4 Checks for vertical tying tie tie F F If it is necessary to comply with structural integrity requirements, then checks 4.2.1.2 and 4.2.1.3 should be carried out [4] with: F Ed = 2 tie F
