Depending upon the source any joist longer than 2 2 4 or 2 5 meters 6 5 7 9 or 8 2 feet requires strutting.

Strutting in timber floor construction.

Timber herringbone strutting should be at least 38 x 38 mm timber and can only be used where the spacing between the joists is less than three times the depth of the joist. They may be the preferred option if there is a lot of pipework or cabling to accommodate between joists as they reduce the amount of drilling that would be required through solid noggings which would weaken the floor. Strutting in timber floors the construction information service this document is available as part of the construction information service. Reduce local deflections by transferring load to adjacent joists load sharing.

Summarises the findings of recent research and offers guidance on the provision of strutting in domestic and non domestic floors covering deflections vibration types where to use and how to install.

Strutting in timber floors strutting plays a useful role in promoting composite structural behaviour of the components that form a timber floor.
