herringbone straps instead of noggins
The herringboning is to stop the joists twisting, as long spans will
tend to do so. Noggings are generally applied to stiffen floors and
support overlapping boards.
Properly installed herringbone stutting will also stiffen the floor. It is
effectively a solid nogging, with all the redundant wood removed, and only
the actually stressed bits remaining.
Obviously, supporting boards is another matter!
