Maximum values for spacings, edge and end distances are unlimited, except in the following cases - for compression members in order to avoid local buckling and to prevent corrosion in exposed members and - for exposed tension members to prevent corrosion. The local buckling resistance of the plate in compression between the fasteners should be calculated according to EN 1993-1-1 using 0,6 pi as buckling length. Local buckling between the fasteners need not to be checked if p lt is smaller than...

Resistance of pins at serviceability limit state NOTE Numerical values for yM may be defined in the National Annex. Recommended values are as follows i gt M2 1,25 yM3 1,25 for hybrid connections or connections under fatigue loading and yM3 1,1 for other design situations jui 1,0 7ms 1,0 yM6,ser 1,0 jui 1,1. 3 Joints subject to fatigue should also satisfy the principles given in EN 1993-1-9. 1 The forces and moments applied to joints at the ultimate limit state shall be determined according to...

2 and 3 are reduction factors dependent on the pitch pi as given in Table 3.8. For intermediate values of pi the value of may be determined by linear interpolation Anet is the net area of the angle. For an unequal-leg angle connected by its smaller leg, Anet should be taken as equal to the net section area of an equivalent equal-leg angle of leg size equal to that of the smaller leg.

6.2.6.7 Beam flange and web in compression 1 The design compression resistance of a beam flange and the adjacent compression zone of the beam web, may be assumed to act at the level of the centre of compression, see 6.2.7. The design compression resistance of the combined beam flange and web is given by the following expression c,flb,Rd Mc,Rd h -f 6.21 h is the depth of the connected beam Mc,Rd is the design moment resistance of the beam cross-section, reduced if necessary to allow for shear,...
