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

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

Garry

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.

Thats correct they are Along the inside of the trusses, parallel to the roof.

I just want to remove part of the brace where it crosses two trusees, Stops having to step Over at one side and step under at the other side.

Ill add some diagonal bracing which i currently dont have.

Thanks for the help Garry

The message from "Garry Nutter" contains these words:

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.

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.

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.
