Bracing in loft?

Question

Longitudinal bracing in loft on trusses , does it need to " firmly abut the solid walls " on bothside , help please urgent .

Answer 1

in the uk if we are talking about masonary walls, there would be longitudinal braces, essentially purlins nailed to every 'rafter'

then also diagonal braces on each side

the trusses are attached to the walls, gable walls, by metal strapping every 2 metres. the strapping is bent and built into the inner skin. it gets attached to rafters and is supported horizontally by noggins. also a wood block is put between the last truss rafter and the wall.

difficult to describe

so no the braces dont have to abut the wall

Answer 2

YES it does.  BOTH sides AND both ends.

This is a normal part of the design and will help prevent the trusses from acting independently of the house walls AND help keep the gables from acting independently as well.  The bracing not only has to "abutt" the wall, but must be secured to the wall in a like manner as it is to the trusses.

This, if you used (2) 16d nails at each truss per the design requirements, then must use the same at your exterior walls.
