Loft Conversion + Plywood Diaphragm
Loft Conversion + Plywood Diaphragm
(OP)
I am looking at a loft conversion. The new stairs will mean the removal of ceiling joints and a timber purlin spanning about 2.8m. The existing ceiling ties appear to counter act the horizontal trust at eaves level. I wany to fix deeper rafters to the existing and also form a diaphragm fixing a plywood deck to the underside of the rafters. This will be fixed to a ties rafter at each end, would this scheme be adequate to resist the trust at eaves?

Your calculations of forces and existing member and connection capacities will prove whether it is feasible and what needs to be reinforced. What do your calculations indicate?
