Bolts

Minimum pitch and minimum edge distance are checked according to SP 16, Table 40.

Minimum pitch is 2.5· d for steel with Ryn ≤ 375 MPa and 3 · d otherwise.

Minimum edge distance is 2 · d for steel with Ryn ≤ 375 MPa and 2.5 · d otherwise in the direction of the shear load. Minimum edge distance is 1.35 · d in the direction perpendicular to the shear load. Minimum edge distances may be smaller under some circumstances specified in SP 16, Table 40. If these conditions are met, user can deactivate the detailing check. However, the check of bolts in bearing may not be performed.

Preloaded bolts

Minimum pitch and minimum edge distance are checked according to SP 16, Table 40.

Minimum pitch is 2.5 · d for steel with Ryn ≤ 375 MPa and 3 · d otherwise.

Minimum edge distance is 1.3 · d.

Welds

The detailing of welds is checked according to SP 16, Cl. 14.1.7. The maximum fillet weld size, kf, should be smaller than 1.2 · tmin, where tmin is the thickness of the thinner connected plate. The minimum fillet weld size is checked according to SP 16, Table 38. If the welded plates have a different yield strength Ryn, each plate is obtained separately and the higher weld size is chosen. The weld type may be set in Code setup. Thickness t is the thickest of the plates being welded.
