- The spacing of link leg perimeters should not exceed 0,75d
- The first link leg perimeters should be within the interval (0,3d;0,5d)
- The spacing of link legs around a perimeter should not exceed 1,5d for the first control perimeter (2d from loaded area)
- The spacing of link legs around a perimeter should not exceed 2,0d for other control perimeters
where d is the effective height of the cross-section.
