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.

3 The 'column-sway' buckling mode of an unstiffened column web in compression illustrated in Figure 6.7 should normally be prevented by constructional restraints. Figure 6.7 'Column-sway' buckling mode ofan unstiffened web Figure 6.7 'Column-sway' buckling mode ofan unstiffened web 4 Stiffeners or supplementary web plates may be used to increase the design resistance of a column web in transverse compression. 5 Transverse stiffeners or appropriate arrangements of diagonal stiffeners may be...

Figure 3.11 Bending moment in a pin Figure 3.11 Bending moment in a pin 1 The provisions in this section apply to weldable structural steels conforming to EN 1993-1-1 and to material thicknesses of 4 mm and over. The provisions also apply to joints in which the mechanical properties of the weld metal are compatible with those of the parent metal, see 4.2. For welds in thinner material reference should be made to EN 1993 part 1.3 and for welds in structural hollow sections in material...

Welded joints between CHS or RHS brace members and channel section chord members

1 Provided that the geometry of the joints is within the range of validity given in Table 7.23, the design resistances of welded joints between hollow section brace members and channel section chord members may be determined using Table 7.24. 2 The secondary moments in the joints caused by their bending stiffness should be taken into account. 3 In a gap type joint, the design axial resistance of the chord cross-section A o,Rd should be determined allowing for the shear force transferred...
