Loft Modification.
 

Some time back we thought WE would convert the loft. That WE was the
wife. Anyway change of plans.


We have a Flink trussed rafters 8 in all. There is a diagonol bracing
going from Bottom Left to Top right across the trusses.

Like here http://www.tra.org.uk/pdf_files/pds4.pdf

Please check Fig 1 Chevron Brace Pinkish in the picture. My brace is
right in the way.

As we dont have the diagonol braces (Green), Only the Chevron type.
Would it be okay to remove part of the Chevron brace and it all still
stay up.



Thanks

Along the inside of the trusses, parallel to the roof?

Of?

I can't see anything pink apart from the timber that is running along
the wall.

Probably.
Remove one, or remove them all?
The point of the chevron braces is to stop the roof top moving in the
line of the ridge.
Without it, under large amounts of wind loading, the roof can in
principle collapse sideways.

Adding diagonal bracing does the same thing as the chevron bracing does.

If you add sufficient diagonal bracing, then you can remove the chevron
bracing.

We'd need some information on roof size and cladding, but I'd expect a
timber about the same size as the chevron brace from one corner of each
side of the roof to the other would do just fine.

They were all left out of our house when it was built around 1970. It's
still up.

I keep meaning to go up and fit 'em.

Well if you need all that I am amazed hundreds of houses I have seen haven't
fallen down by now. It's only the ones that have a roof looking like the
diagram that have had the roof lift or fall off in gales! All a bit OTT and
not required from what I have seen in 25 years.

Yep, roughly same age of house here, has got the "longitudinal binders"
but nothing corresponding to the "diagonal wind brace" or "chevron braces"

To be fair, ours is probably adequately supported by the concrete walls
between houses in the terrace.

In practice.

As long as plenty of nails have been used at each joint, rather than
just one or two allowing each joint to easily pivot, I suspect it'll be
just fine.
