Framing components

Framing guidelines for cold formed steel

The FRAMECAD System can produce frames to suit a large range of building designs. This page details the typical framing members which may be needed to produce a building using the FRAMECAD System.

Bottom plates
Bottom plates are horizontal members fixed to the bottom of the studs and should be fully supported below load-bearing studs. Fixings through the bottom plate are used to secure frames to the floor.
Steel K-bracing, formed with FRAMECAD frame sections as bracing in the line of wall frames, may be used to provide bracing resistance to walls. K-braces can be used to provide frame squaring and stiffness to aid construction.
Webbed floor joist
The webbed floor joist is a lightweight steel truss consisting of parallel chords and a triangulated web system. These are designed at various depths to span between support points.
Common studs
Common studs are standard wall studs which are not located beside an opening. These studs must be evenly spaced to accommodate loads, lining and cladding.
Jamb studs
Located either side of openings in the frame, jamb studs provide extra support for lintels above windows, doors and arch ways
Lintels are horizontal structures within a wall spanning between jamb studs over door and window openings
Nogging can either be a continuous length of C section with lip and web notches for the studs to pass through, or short pieces cut between the studs at alternate staggered heights. Typically, short walls will have one line of nogs, for taller walls, their can be 2-3 lines of nogs. Consult your local building code or talk to a FRAMECAD expert.
Top plates
Top plates are horizontal structural members fixed to the top of the studs. On load-bearing walls carrying a light load, top plates can transfer loads from the roof to the studs where the studs are not located directly below the trusses. For walls carrying heavy loads, top plates would need to be strengthened with L-header plates if studs are not located directly below the truss
