Rigid End Frame (Half Load)
Used where future expansion is not anticipated but where end wall must
be free of vertical obstruction because of glass, masonry, or open space.
A Half Load Rigid End Frame should be specified for buildings having
an end wall that must be free of vertical obstructions because of requirements
for open space or “other” materials (masonry, glass, etc.) This Rigid
End Frame may be any of the 5 clear span, primary frame types (RF, FW,
TB, SS, or LT). However, if interior posts of multi-span frames are
acceptable in the end wall opening, then any one of the 8 primary types
may be used.
Although designed for only half-bay loading, the appearance of these
Rigid End Frames is similar to interior primary frames. Width, eave
height, roof slopes, and geometry (i.e. gable or single slope) of Half
Load Rigid End Frames will therefore be same as primary frames in building.
End walls on bearing frame building have By-pass Girts as standard,
with Inset Girts optional. Inset Girts/flush Wall condition (where
end post depth is limited to 9” to contain these columns entirely within
the girt space) are also optional but may only be used on building whose
peak height does not exceed 35ft.
