The bottom plate that stopped under a bracing wall
A load path with a gap in it.
In short: A bottom plate recorded discontinuous under a loadbearing and bracing wall in Austral.
What the bottom plate does
It is the timber the wall studs sit on, and it is how the wall transfers load into the floor or slab below. Under a bracing wall it also carries the racking load the bracing collects.
What was recorded
Discontinuous loadbearing and bracing walls, recorded at high severity on an Austral frame inspection.
Why a break matters
The load path assumes continuity. Interrupt the plate under a bracing wall and the racking load has to find another route, usually through fixings that were never sized for it.
How it happens
A plate cut for a service, a doorway set out late, or two lengths that never met. It is easy to do and easy to miss.
Fixing it
At frame stage, splicing or replacing the plate. After lining, it is an investigation and an engineer.
