I'm trying to work out how to provide lateral restraint for the angled wall on the left (if it's required at all). I'm using metal web joists and it's only single storey.
On the TRA site (page 13 at in https://www.tra.org.uk/wp-content/uploads/dlm_uploads/tra_metal_joists__single_final.pdf), it shows a metal strap going into the blocks. However, if I did this then the 90 degree bend would stick out in the cavity and not sit flush against the wall. I don't know whether anybody else has had a similar situation or knows how to do it?
The roof designer pointed me to building control and build control said it's up to the principle designer . Maybe it's a structural engineer question? My gut feeling is that the joists will provide some lateral restraint as they are built into the wall, but would it be enough?
Also, are lateral restraint straps required on the shorter walls too e.g. the 2480 wall that runs parallel to the joists?
