Ah great minds think alike, yes, that's what I mean, beefing up the lowest bit, should be straightforward?
Yeah just crack on, I wouldn’t bother calculating.
Nail a bit of 2x4 on the bottom half and you’re good to go biggrin

Was going to watch that but it's making me feel sea-sick! Why do people feel the need to wave the camera around like a drunken sailor? wobblevomit
To help me, is it worth watching or did you post it for entertainment purposes hehe

He seems to have found a reasonable solution - but I do note that calculations were done before the reciprocating saw came out.

He's an engineer who sees things differently and normally has a different opinion to others apparently, he's banged some 6x2's in an X shape and cut the trusses. His own calcs and no building regs needed in his state for that work. He admits on the comments it's weaker and in future he'd change his design and it would be a concern if he ever sold.....tells me all I need to know!

Yes, cheers, he’s an engineer like me, a professional, although scissor trusses will not give me the space at the ends that I’m looking for.

A quick search for raised tie roof truss found this picture

Note the way the lower section of the rafter is expanded with another section of timber.
Also note what it's bearing onto...
It's a point load onto a wall?
It's not a point load, there is some flex in the design as it's not a triangular section below the lowest chord, so there is some load trying to spread the walls and spread the roof.

In that design there is a floor, which you don't have in your plan, the floor is providing restraint between the walls, and stopping the roof from spreading.

Dynamically it will be a point load because of the restraint provided by the floor, remove the floor and there's another load to consider.

My best guess is your plan will be fine, if it's executed properly, but I would get the calculations done rather than guessing at it, particularly as it might cause you issues on sale down the line.

Ok, I'll try to watch it...

I did see that video before in fact - if I was being really honest he’s used American high school trigonometry and ended up with a safety factor of 9 which is utterly ridiculous and over the top.

Anyway cheers everyone, Btw I have some good ideas for other types of roof supports, hit me up if you need me to engineer something for you.
