A load bearing wall is one which carries vertical loads from the construction above or lateral loads resulting from the wind.
These loads may act separately or in combination. Both internal and external walls may be load bearing. Elsek Steel Panel
recommends the following for the load bearing walls:
Internal walls which do not support truss loads are considered non-load bearing. Elsek Steel
Panel recommends the following for non-load bearing walls:
Steel framing is fastened to the floor structure through the bottom plate after all panels
have been correctly aligned and plumbed. For concrete floor slabs the frame is fixed in
place by using masonry anchors, which are generally hammer driven nails, expanding shell
anchors or chemical anchors. Exact recommendations for the type and frequency of anchors
would be available from steel suppliers or the engineer. The wall panels are usually connected
together by mechanical fasteners such as self-drilling screws.
External Door and Window Frames: The same door and window frames used in timber-framed construction
are also used in steel-framed construction. If aluminum window frames are fitted into timber, they
can be installed by fastening through the jamb studs into the back of the reveal after positioning.
If it is not possible to secret-fix the frame, as may be the case with a window or door head,
self-drilling screws of appropriate length can be driven through the frame and packing into the
steel framing. The same type of screws may also be used to fasten aluminum window frames direct
to steel frame openings.
Internal Door Frames Timber door frames in internal walls
can be secret-fixed through the back of jamb studs with screws or nails. Alternatively the frame may
be fastened through the jamb into the studs with self-drilling screws.
If required in the external walls, reflective foil sarking may be attached to the external flange of the steel studs with self-drilling screws fitted with 25mm flat fiber washers. Alternatively wafer head screws may be used. Wire brick ties which simply clip on to steel studs are available for brick veneer construction. For single wall construction, fiber cement sheeting can be fixed to steel frames with self-drilling, self-embedding head screws. Timber weatherboards can be fastened to steel studs with extended point countersunk head self-drilling screws. Steel sheet cladding is also fixed with self-drilling screws.
